Christian Theism: Its Claims and Sanctions. By D. B. Purinton, LL. D. New York and London: G. P. Putnam's Sons. Pp. 303. Price, $1.75.

The author of this book, who is Professor of Metaphysics in West Virginia University, in presenting his thesis, has had three objects in view, viz. — to construct a progressive argument logical in its method and correct in its general conclusions, and likewise defensible in each individual part and item of it; to free the subject from ordinary obscurities and difScultics; and to present it, "without dodging any of its profound problems," in such a clear and simple manner as to commend it to the general reader who is willing to think as he reads. Christian theism being presented as a fact, making positive, bold, radical, uncompromising, and universal claims, the author presents as arguments in support of it: Intelligence in nature, the eutaxiological argument; volition in nature, the teleological argument; the personality of God, or the intuitive argument; the goodness of God, or the historical argument; the unity of God, or the monistic argument; and the infinity of God, or the causal argument. As "antitheistic errors" are combated materialism, pantheism, positivism, and agnosticism. The last system is regarded as "an ingenious combination and modification" of the other three systems, which in its present phase has taken shape and name from Herbert Spencer, "the great agnostic of modern times," a study of whose works" produces a profound conviction of his depth and patience of thought, his breadth and profundity of scholarship, his fertility of imagination, and his frankness and earnestness of purpose." This system is reviewed in an attempt to show it to be logically self-destructive. A comparison of "Evolution and Christian Theism" leads to the conclusion that most of the objections to the former scheme lie not so much against evolution as against the mechanical form of it. "Nature is not a machine, for it is plastic, progressive, improvable, while a machine is neither of these. Matter can reveal higher and still higher forms of organism, but can never create them. Matter, motion, and force, without a directive idea, can do nothing toward explaining a rationally developed universe. But why exclude a creative and directive idea? Let that idea be God. There is not a single fact in nature against the existence of a personal God or the occurrence of an act of creation. There are many facts in favor of both. Why not admit that God made the world and sustains it in being? That admission would not blot out evolution, but would view it as a possible or it may be probable method of God's creative and providential work." The question would then be not "evolution versus creation," but "evolution the method of creation." The question of immortality is also considered.

The Land and the Community. By S. W. Thackeray. New York: D. Appleton & Co. Pp. 223. Price, $1.

This work bears the indorsement of Henry George, who supplies it with a preface. In its original form it was presented as a thesis to the University of Cambridge for the degree of Doctor of Laws. The essay has been expanded and arranged for reference. It is commended for the fullness and clearness with which the historical and legal aspects of the question have been dwelt upon, the attention given in it to the matter of compensation, and the religious feeling and conservative disposition manifested in it throughout. It serves the office, according to Mr. George, of a clear and simple exposition of essential principles and important facts, which shall give force and definiteness to the ideas growing out of the doctrine of equality of right to the use of the land, make manifest their conformity with historical experience and religious truth, put them in such a relation that the rec- ognition of common rights in land may strengthen, not weaken, the recognition of individual rights in the products of labor; and supply answers to the arguments urged upon the other side. Mr. Thackeray begins his thesis with a history of land tenure in England, divided into the pre-feudal, feudal, and post-feudal periods, in which the subject is treated with special reference to the rights and interests of the community as distinct from the individual interests involved. The origin of the present system is traced to the acts of 1656 and 1660, "which turned mili- tary tenures into free and common socage." Community rights were trampled upon or ignored under these acts, the custom of making settlements grew up and was recog- nized, and lands before common were in- closed without effective resistance till about half a century ago, when laws were passed restricting the right. The key to the future of land tenure may be found in the exercise of the right of eminent domain, which the author regards as an assertion of the state's ownership and its right to change tenants on condition of the new tenant indemnifying the old one for the damage he may suffer. The right of the community to resume its possession of the land being, as the author believes, shown, a second part of the work is occupied with the questions relating to compensation. The rights of the community may be reasserted and secured by requiring those who occupy or cultivate the land to pay to the community a full equivalent for the special privileges which they thus enjoy that is, through the appropriation of ground-rents by taxation, and applying the proceeds for the benefit of the whole com- munity. A plan is outlined for effecting the change with the least harshness; and the beneficial effects anticipated from it are enumerated. As to those who may be supposed to be injured by the change re- duced to landlords the conclusion is reached that most landlords would lose nothing with- out receiving advantages nearly if not fully

��compensating them ; while the others, if not relatively as great gainers as other classes of the community, would not be absolute losers. The landlords' claims for compensation are examined and found not good, either in law or equity in fact, the claim of the commu- nity against them is assumed to be the bet- ter one ; and, finally, they are invited man- fully to accept the situation, and themselves lead in recognizing the justice of the new dispensation.

Studies in Pedagogy. By Thomas J. Mor- gan. Boston : Silver, Burdett & Co. Pp. 355. Price, $1.15.

The author, Principal of the Rhode Island State Normal School, and before that of normal schools at Potsdam, N. Y., and Peru, Neb., has embodied in this volume the fruits of many years of observation, reading, think- ing, and experience in the exercise of his profession, and makes in offering them " an earnest effort to contribute toward the pro- motion of higher ideals of education and bet- ter methods of teaching." His view of edu- cation in the general sense is a broad one, and embraces all that marks the difference between what a child is by nature at birth and that which he becomes by growth, training, and experience. In this sense, na- ture is embraced as one of the greatest forces of education. In the narrower sense, to the consideration of which this book is chiefly devoted, education is restricted to the effect produced upon the young mind by those who seek purposely to influence it, or the direct influence of teachers and schools. Its most important factor is training, which here signifies such a control exercised by the teacher over the pupil as will lead him so to use his faculties as to secure their completest development ; and which has for its imme- diate end the evolution of power. These faculties may be grouped under the heads of acquiring, understanding, reproducing, using, and expressing knowledge, each of which, again, includes its own several topics and means. More nearly than any other work of the teacher it meets the ideal of educa- tion ; it is an essential preliminary to a suc- cessful work of instruction ; and is the pro- cess that best prepares the student for the active duties of life. The special applica- tions of training discussed are those to the LITERARY NOTICES.

��senses, the imagination, thinking, the sensi- bilities, language, the will, learning music, the use of books, and "training for free- dom." There must be method in the per- formance of the teacher's work ; hence we have a series of chapters on "Methodology." In " Man and his Method " the principle is enforced that, important as the method may be, the man behind it, who should inspire it, is more so. Method in questioning and in teaching arithmetic is treated with some full- ness. The value and purpose of examina- tions are estimated. "The Ideal School- master " holds up the objective toward which every teacher should strive. " The True Function of a Normal School " is a paper which was awarded the prize of the Ameri- can Institute of Instruction in 1885. "Ad- vice to Young Teachers " embodies the sub- stance of several addresses to graduating classes of the normal school. In them " Independent Thinking " and " Training for Citizenship " are prominent topics.

Geology of the Quicksilver Deposits of the Pacific Slope, with an Atlas. By George F. Becker. Washington : Gov- ernment Printing-Office (United States Geological Survey). Pp. 486, with seven Plates. Atlas, 14 sheets. Price, $2.

The field work of the investigations re- corded in this volume occupied the most of three seasons, beginning in 1883. There remained to complete the examinations sat- isfactorily the investigation of some impor- tant general problems affecting the whole region. Among these were indications af- forded by the paleontology and structure of a previously undetermined non-conformity existing in the Coast Ranges, These were confirmed. Another investigation related to a possible connection between the forma- tion of ore deposits and the metamorphism of the Mesozoic rocks. A third special in- quiry was directed to determining whether the deposition of cinnabar is still taking place at Sulphur Bank and Steamboat Springs, and, if so, under what conditions the solution and precipitation of cinnabar and the accompanying mineral occur. The author finds that the quicksilver deposits lie along the great axes of disturbance of the world. One of these is on the line of the principal mountain systems of Europe and Asia, and the other coincides with the west- vol. xxxvi. 36

��era ranges of the Cordilleran system of America. The principal mines are at Al- maden in Spain, Idria in Austria, Huan- cavelica in Peru, and those in California. From 1850 to 1886 California supplied nearly half the product of the world, but is not probably destined to maintain the same rank in the future. Quicksilver was first recognized as occurring at the croppings of the new Almaden mine in 1845. But few other minerals occur in considerable quanti- ties with the ore. Among them are pyrite or marcasitc, arsenic and antimony, and sometimes copper ores, while other metal- liferous minerals arc comparatively rare. The principal gangue seems to be silica or carbonates. The cinnabar appears to have been deposited solely in pre-existing open- ings, and never by substitution for rock. The fissure systems, which are always pres- ent, are very irregular, and deposits can not conveniently be classified according to exist- ing systems. All of them seem to have proba- bly been deposited in the same way from hot sulphur springs. At Sulphur Bank cinnabar is now being precipitated from heated waters largely by the action of ammonia ; at Steam- boat Springs it is being deposited without complications from the presence of ammonia. In dealing with the processes by which the ore has been dissolved and precipitated in nature, it has been shown by experiment and analysis that cinnabar unites with sodi- um sulphide in various proportions, forming soluble double sulphides, and that these compounds can exist in such waters as flow from Sulphur Bank and Steamboat Springs, either at ordinary temperatures or above the boiling-point. The quicksilver is probably derived from granitic rocks by the action of heated sulphur waters, which rise through the granite from the foci of volcanic activity below that rock.

Coal and the Coal Mines. By Homer Greene. Boston and New York : Houghton, Mifflin & Co. Pp. 246. Price, 75 cents.

This is a volume of the attractive " Riv- erside Library for Young People," and is intended to tell readers, in a style free from minute details and technicalities, all that re- lates to coal and to procuring it from the earth. The information has been gained for the most part, the author says, from per-

��sonal experience in the mines ; but little of it comes from books, for the literature of the special subject is meager. Beginning at the beginning, we have a brief reference to the geological record previous to coal. Then the composition of coal is elucidated, the time when it was formed is defined, and the situation of the coal-beds is described. The history as it relates to our own period be- gins with the discovery of coal and its intro- duction into use. The account of the mines includes the way into them, the plan of a typical mine, " the miner at work," the ob- stacles and dangers he has to encounter, and the anthracite breakers. A chapter is given to the bituminous coal mines. The account of " The Boy Workers at the Mines " is of particular interest to the young peo- ple, and the chapter on " Miners and their Wages " to searchers for facts.

A Handbook of Obstetrical Nursing. By Anna M. Fcjllerton, M. D. Philadel- phia: P. Blakiston, Son & Co. Pp. 214. Price, $1.25.

The great number and variety of the things to be attended to in a case of child- birth, many of which are not so familiar as the matters concerned in the treatment of disease, together with their importance as affecting two lives, make a special manual on this subject highly desirable for the nurse. It would be well, also, for every mother to have read a book of this sort be- fore her confinement, in order that she may understand and co-operate in the efforts of the physician and nurse for her wel- fare, and be protected from the antiquated wisdom and dismal tales of injudicious friends. It would be difficult to make a more comprehensive and practical book than Dr. Fullerton's. It is an outgrowth of the extensive practice of the hospital and the systematic instruction of the nurses' train- ing-school. The teachings which it embodies are chiefly the substance of a series of lect- ures delivered yearly by Dr. Anna E. Broo- mall to the nurse-pupils of the Woman's Hospital of Philadelphia, and they are fol- lowed in the Maternity connected with that hospital. The whole ground from the man- agement of pregnancy to the ailments of early infancy is covered. Directions, suffi- ciently detailed for the use of a trained nurse, are given for the care of the patient

��immediately before and during labor, for the care of the new-born infant, and the man- agement of the lying-in. The appliances which the nurse will need to use, and the articles of clothing for mother and child, are described, and many of them are figured. The Jenness-Miller reformed garments are indorsed. A short chapter is devoted to the appearance of infants in health and disease. In the chapter on ailments of infancy the couvcuse, or brooder, for keeping premature infants warm, is described and figured. Throughout the volume reference is made easy by printing the subject of each para- graph in the margin.

Fossil Fishes and Fossil Plants of the Triassic Rocks of New Jersey and the Connecticut Valley. By John S. New- berry. Washington : Government Print- ing-Office (United States Geological Sur- vey). Pp. 152, with 26 Plates. Price, 1.

The Triassic rocks, according to Prof. Newberry, probably furnished the first fos- sils collected on this continent : fishes at Durham and Sunderland, Conn. ; plants at Richmond, Va. ; and the so-called bird-tracks at Turner's Falls, Mass. While the forma- tion has received considerable attention in detail, no systematic collection or thorough study of its fauna or flora as a whole was attempted till about 1880, when Prof. Fon- taine took it up for the fossil plants of the Virginia and North Carolina Mesozoic coal basins. His publication established the parallelism of our new red sandstone with the keuper of Europe. The animal remains were left to be studied, and that work was taken up by Prof. Newberry, with results that are presented in this volume. The special studies are preceded by a geological sketch of the new red sandstone regions of New Jersey and Connecticut, concerning the relations of which to one another there ap- pear to be different opinions. The Triassic rocks are about five thousand feet thick and present some singularities of structure. The materials were probably derived from the adjacent highlands. The rocks are charac- terized by their red color, derived from the oxide of iron, the presence of which proves that they contained but little organic matter when deposited. Their relations to the Triassic beds of the interior and the western

��margin of the continent can hardly be es- tablished without larger collections of fossils from Western localities. The fishes, though so far as yet known representing only six genera and about twenty -five species, are locally very numerous, and are found in many places. The principal sites represented in the volume are Boonton, N. J. ; Durham, Conn. ; and Turner's Falls, Mass. ; while they have also been obtained at Plainfield, Mil- ford, Newark, and near Hoboken, N. J., aud at Middletown, Sudbury, Chicopee, Amherst, and Hadley's Falls, in the Connecticut Val- ley. The several species are described in detail and illustrated by figures apparently of the size of nature. We are glad to learn that the author's collection, which is the largest yet made, is safely deposited in the fire-proof Geological Museum of Columbia College.

Ligeros Apuntes sobre el Clima de la Republica Argentina. (Notes on the Climate of the Argentine Republic.) By Gualterio G. Davis, Director of the Argentine Meteorological Office, Buenos Ayres. Pp. 254, with 27 Plates and Charts.

The Argentine Meteorological Office was established in 1872, and was organized un- der the direction of Dr. B. A. Gould, whom Mr. Davis succeeded on his retirement after twelve years of service. It has gradually extended its sphere of operations to the most remote parts of the country, and now receives observations of the more important weather phenomena from sixty-six stations, and of rainfall from ninety more. The six volumes of the publications of the office embody the results of observations taken at twenty -six points, with analytical discussions of the data, and deductions of the general laws of atmospheric changes ; and the an- nual reports contain a large part of the re- sults reached in the corresponding years. But a more compact work was needed to embody a summary of these results adapted to practical use ; and the attempt is made to supply this need in the present volume, which is intended to put within reach of the colonist, the farmer, and the doctor such meteorological facts as bear upon their in- dustrial enterprises and hygienic studies. Twenty-one stations are selected as typical of the various climatological conditions that

��prevail in all parts of the republic. The lines extend from the Atlantic coast to the western points of the country, and from lati- tude 54 53' in Tierra del Fuego to Salta in latitude 26 46' 20" ; the altitudes range from 8 metres to 2,845 metres above the level of the sea. To each of these stations is allotted its given space for general de- scription, with tables representing the vari- ous meteorological facts in detail and a graphic chart. The publication thus fur- nishes a summary of the local climates, de- duced from several years' observations of the various districts of which the particular stations are the centers.

Monopolies and the People. By Charles W. Baker, C. E. New York : G. P. Putnam's Sons. Pp. 263. Price, $1.25. There is abundant reason for including monopoly among the " Questions of the Day," as is done in this volume. Trusts and monopolies exist, as the author shows at length in a series of chapters, in manufactur- ing, mining, transportation, trade, and labor. There are monopolies constructed directly by those who profit from them, monopolies created by municipal enactments, and mo- nopolies supported by governmental policy. The author next examines the theory of uni- versal competition, after which he states the laws of modern competition. He denies that " the prevalence of monopolies evidences the decay of the nobler aspirations of humanity." He regards them as an outgrowth of the modern conditions of industry, and, while they involve evils, he affirms that "the remedy for the evils of monopoly is not abolition, but control." He then specifies some of these evils, and names also some ameliorating influences. The remedies that have been proposed are based on one or the other of the opposite principles, individu- alism and societism, or communism. Mr. Baker maintains that neither should be adopted wholly, and in his concluding chap- ter advocates the owning of all railroads by the Government, and their operation by cor- porations which should pay a rental for the privilege ; the owning of mines by the States, which should lease them to private parties for operation. Water-works, gas and elec- tric lighting plants, street railways, and simi- lar local enterprises should be owned by the cities in which they are located, and also

��operated by private companies. Mr. Baker does not favor the same procedure in the case of monopolies in trade and manufactur- ing. But he would legalize them, and then force them to let daylight in upon their op- erations and agreements, and apply to them the principle of non-discrimination.

Aryan Sun- My f lis the Origin of Religions (Nims & Knight) is the title of a book de- signed to show that the mythology of this great primitive race is the parent of the chief modern religions, just as the race itself is the parent of the peoples who hold these religions. In the Aryan mythology we have the immaculate conception, from which the son of heaven, the sun, is born, at the time of the December solstice. We have the twelve signs of the zodiac as his disciples ; his temptation, persecution, and execution. There is a descent of the sun into hades, when he enters the sign Capricornus and appears to remain three days at his lowest point. The Aryans observed baptism, sac- rifice, and the eucharist, and the doctrines of original sin and the fallen condition of man were not unknown to them. When we come down to the Hindus, who have written religious records, we find the same features and more. So also among the Persians, the Egyptians, the Chinese, the Greeks, the Scandinavians, and the ancient Mexicans. Some of the same ideas are found among other ancient nations of the Old World, and among the American Indians. " Ancestral and other systems of worship," says Mr. Charles Morris, in the introduction which he contributes to the volume, "have influ- enced religious practice and ceremony to a marked extent, but have had much less to do with the growth of dogma than the in- tricate details of the history of the gods, to which the numerous phenomena of nature gave rise. Over religious belief the sun has exercised a dominant influence, and still faintly yet distinguishably shines through the most opaquely obscure of modern theo- logical dogmas."

��In a paper on Teaching School Children to Think (D. Appleton & Co.), Prof. George B. Newcomb discusses first the question, " What is the capacity and exercise of the mind which is indicated by the terms ' thought '

��and ' thinking ' ? " He shows that in the reaction from the old mechanical drill we should avoid going to the opposite extreme of taxing the child's mind beyond its pow- ers. The faculty of thinking is a growth, and needs to be dealt with according to the stage of development it has reached. Ca- pacity to form abstract ideas and reason con- secutively does not come at once ; " yet long before reasoning, strictly so called, is devel- oped, there is rationality, the exercise of in- telligence in unifying the scattered particu- lars of sense ; in correlating facts and light- ing up one fact by another " ; and it is all alive in the child's mind, in the curiosity that asks the reason why. While children dislike remote abstractions, they are capable of general thought and rational connecting, and make crude attempts at rational synthe- sis. The manifestations of these faculties may be watched for and taken advantage of and directed as they appear, and the child thus be led gradually up to the habit of ra- tional thought on every subject. This pre- cept partly furnishes the answer to the au- thor's second question, "In what sense or within what limits, if any, should the devel- opment of thought be a prominent aim in the training of school children ? " A third question, involving the consideration of ways and means for developing rational intelli- gence in the pupil, is too large for treatment in a single paper ; and upon it the author aims only to enunciate broad principles or make helpful suggestions without going into details.

In A Ramblei-'s Lease, Mr. Bradford Torrey, one of the most pleasant of our rural essayists, assumes the position of a leasehold tenant of other people's fields and woods to the extent of the aesthetic enjoy- ment and opportunities for the study of life and nature that they afford. He there- fore makes himself at home in them, and keeps company with the trees and flowers and insects and birds ; with some of which he has enjoyed privileges of rarely close association. The present volume contains some of the fruits which he has gathered in these possessions ; seemly and agreeable fruits in every way, and flavored with occa- sional choice grains of wit. In it he intro- duces us to the wild birds which he has be- come so intimate with as to feed them by

The Anatomy of Astrangia Dana, pub- lished in quarto form by the Smithsonian Institution, comprises six lithographs from drawings made by A. Sonrel, under the di- rection of Prof. Agassiz in 1S49, illustrating the structure of that madrepore, the only representative of the family in shallow New England waters, with text explaining the plates by J. Walter Fcwkes. Although there has been a great advance in histological methods since the figures were drawn, it has hardly extended to the minute anatomy of these creatures ; so that the representations are nearly as fresh as if they had been drawn to-day. Whatever may be lacking to bring them up to the present state of knowledge is supplied in Mr. Fewkes's descriptions, which are based on studies of living speci- mens.

Studies of the Macrochires, Morphological and otherwise, with the View of indicating their Relationships and defining their Several Positions in the System, by R. W. Shufeldt, M. D., bear upon the comparative anatomy and place of the swifts, whip-poor-wills, and humming-birds. The author had already proposed a separate order for the Trochili, or humming-birds, and is more than ever convinced of the correctness of his scheme. In the present essay he proposes a new group or order that of Cypseli for the swifts. This order, were it represented by a circle, would be found just outside the passerine circle, " but tangent to a point in its periphery opposite the swallows.

In a monograph on The World's Supply of Fuel, Prof. W J Me Gee describes rock gas and its occurrence ; accounts for its for- mation by the decomposition of the organic matter contained in sediments ; answers in the affirmative the question whether it is still forming, and adds that it will probably continue to form indefinitely, though at a

��decreasing rate; and predicts that it is destined to be, after the coal has been ex- hausted, the world's unfailing supply of fuel and light.

The address of Prof. Charles A. White, aa Vice-President of the Geological Section of the American Association, is devoted to the survey and definition of Tlie North American Mesozoic, particularly of the formation called Triassic. There are doubts about the corre- spondence of this with European forma- tions ; and this and certain other facts give occasion for the expression, with some full- ness, of the opinion that we must not expect to discover a precise correspondence, either in time or character, in the geological history of our own and other continents, or an ex- act identity of formations in them. Hence, with all respect to European classification and names, which may still be used tenta- tively in each of the great divisions of the earth, and with reference to the ultimate establishment of a universal system, it is for North American geologists to elaborate a scheme for the formations of our own con- tinent.

In a pair of papers on Meteorites and what they teach us, Dr. H. Hensoldt sum- marizes what has been learned about me- teorites, and declares his own theory as to their origin. This theory is based on the presence of liquid carbonic acid in the cavi- ties of these bodies. The fluid is ascer- tained to be carbonic acid by the instanta- neous change of form which it undergoes between 30 and 31 C, which is character- istic of that substance. Now, carbonic acid can not be liquefied except under a pressure which exists in nature only deep in the earth. Hence the meteorites must have been at some time subjected to such a press- ure. It is therefore concluded that they have come from the interior of some plane- tary body which has been rent by an explo- sion.

Proceedings of the Boston Society of Natu- ral History, Vol. XXIV, contains the reports of the society and its proceedings, with the papers read, from May, 1888, to May, 1889. Prof. Hyatt's report as curator of the muse- um shows that that institution is growing at a healthy rate, and the arrangement of its collections is going forward. The papers relate to various topics of biology, geology,

��and archaeology. Among thern are those of Prof. Hyatt on the "Evolution of the Fauna of the Lower Lias " ; of Mr. S. H. Scudder on a Palaeozoic " Cockroach Fauna " at Richmond, Ohio; of Prof. Marcou on " Canadian Geological Classification for the Province of Quebec " ; of Mr. Alfred C. Lane on the " Geology of Nahant " ; of Mr. War- ren Upham on " Marine Shells and Frag- ments of Shells in the Till near Boston " ; of Mr. Samuel Garman on the " Evolution of the Rattlesnake " ; and of Prof. Goodall on the " Life and Work of Dr. Asa Gray."

Several archaeological papers, which ap- pear in this volume of the " Proceedings," are also published separately by the Peabody Museum of American Archaeology and Eth- nology, under the title of Palceolilhic Man in Eastern and Central America. They are "Early Man in the Delaware Valley," in- cluding an account of the lately discovered " Rock Shelter " at Naaman's Creek, and descriptions of Palaeolithic implements ; and an account of an implement from the In- diana gravel, by Hilborne T. Cresson ; Prof. G. F. Wright's paper on the " Age of the Philadelphia Red Gravel " ; " Water-worn Implements from the Delaware River," by Dr. C. C. Abbott ; and remarks on the whole subject by President F. W. Putnam. Prof. Wright's paper bears upon the age of the rock shelter and of the implements in the Delaware Valley described by Mr. Cresson, which the author decides are older (perhaps by a thousand years) than the deposits at Trenton, N. J., Loveland and Madisonville, Ohio, Little Falls, Minn., and Medora, Ind. (Cresson).

An Obsidian Implement from Pleistocene Deposits in Nevada, by WJ Mc Gee, discusses the age of a handsome neolithic work found on Walker River, to which the author has already made reference in the " Monthly " (November, 1888, p. 25). The solution of the question is partly dependent upon the char- acter of the occurrence of the implement whether it be adventitious or normally in situ. The deposit being unconsolidated, this can not be determined certainly without the help of other human relics found in the same place to keep it company ; and such have not been found. But, since the implement was ob- served, the discovery of other extremely an- cient relics in various parts of the country

��has given color to the hypothesis that this was an original deposit ; and the author now inclines to that view.

The Aborigines of the District of Colum- bia and the Lower Potomac a symposium in the Anthropological Society of Washing- ton besides an address by Otis T. Mason, introducing the subject, contains papers on " The Geological Antecedents of Man in the Potomac Valley," by W J McGee ; " The Palaeolithic Period in the District, of Colum- bia," by Thomas Wilson ; " Ancient Village Sites and Aboriginal Workshops," by S. V. Proudfitt ; " The Pottery and Textiles of the Tide- Water Region," by W. H. Holmes; "The Shell Mounds of the Potomac and Micomico," by Elmer R. Reynolds ; " Indian Tribes of the District," by James Mooney ; and a discussion by Prof. F. W. Putnam.

Of six additional " Bulletins " of the United States Geological Survey, No. 48 is On the Form and Position of the Sea-Level, with special reference to its dependence on superficial masses symmetrically disposed about a normal to the earth's surface, by Robert Simpson Woodward. The treatise is mathematical, and relates to a problem of peculiar difficulty, the solution of which has been as yet only approached. The same author's Latitudes and Longitudes of Certain Points in Missouri, Kansas, and Neiv Mex- ico, constituting " Bulletin No. 49," relates to the processes of determination at Oswego, Elk Falls, and Fort Scott, Kan. ; Springfield and Bolivar, Mo. ; and Albuquerque, N. M. The author has endeavored to collect, arrange, and discuss the observations in such a man- ner as to render their results most useful for the purposes of geography and geodesy. Bulletin No. 50, also by Mr. Woodward, con- sists of Formulas and Tables to facilitate the Construction of Maps. The tables were pre- pared for the Division of Geography in 1885-86. Constant use since then has demonstrated their utility. They have been revised and extended, and are accompanied by an explanatory text. Dr. Charles A. Wldte gives, in Bulletin No. 51, descriptions of some Invertebrate Fossils from the Pacific Coast. They fall under five headings : " New Mollusca from the Chico-Tejon Series of Cali- fornia," representing nineteen new species and one new genus ; " The Occurrence of Equiv- alents of the Chico-Tejon Series in Oregon

��and Washington Territory " ; " Cretaceous Fossils from Vancouver Island Region," in which an intimate relation is shown with the fauna of the Chico group ; " The Molluscan Fauna of the Puget Group," unique and indi- cating deposition in a large estuary; and " Mesozoic Mollusca from the Southern Coast of the Alaskan Peninsula," which are re- garded as new. No. 52, Subaerial Decay of Bocks and Origin of the Red Color of Cer- tain Formations, relates studies of the sub- ject by Israel Clark Russell, chiefly among the Appalachian Mountains in Virginia and North Carolina. The author believes that changes by decay have' a wider geological bearing than has generally been assigned to them ; and that the red color of certain sandstones is due to a coating of their par- ticles with ferric oxide received during the process of subaerial decay of the rocks of the debris of which they are composed. The last of the present series of Bulletins No. 53 is a study of The Geology of Nantucket, by Prof. N. S. Shaler. The island is re- garded, together with the accompanying southern Massachusetts coast, Martha's Vine- yard, Long Island, etc., as " the dissevered remains of a great shelf formed of the debris brought to its present position by the glacial ice and by the streams of water which flowed beneath it."

The United States Department of Agri- culture, Division of Entomology, publishes an investigation of The Root-knot Disease of the Peach, Orange, and other Plants in Florida, due to the Work of Anguilhda, made under its direction, in 1888, by Dr. ./. C. Neal. A large number of species of plants are attacked by the worms, whose depredations are marked by the appearance of swellings or " knots " on the roots, and threaten to be damaging. The author has made studies of the nature of the insect and its ravages, and has experi- mented with reference to the remedies. His report is illustrated with plates representing attacked roots and the life-history of the enemy.

The June number of the Journal of Mor- phology, Vol. Ill, No. 1 (Prof. C. 0. Whit- man and Edward Phelps Allis, Jr., editors ; Ginn & Co.), contains articles on " The Acti- niaria of the Bahama Islands," by Dr. J. Play- fair McMurrich ; " Contributions to the Com- parative Osteology of the Families of North

��American Passeres," and " Notes on the Anatomy of Spcotyto cunicularia hypogea^ by Dr. R. W. Shufeldt ; and " Variation of the Spinal Nerves in the Caudal Region of the Domestic Pigeon," by James I. Peck. The September number, Vol. Ill, No. 2, has "The Mechanical Causes of the Develop- ment of the Hard Parts of the Mammalia," by E. D. Cope ; and " The Embryology of Blatta germanica and Doryphora decem- lincata " the cockroach and the Colorado potato beetle by William M. Wheeler.

A Bibliography of Geodesy was compiled by Prof. J. Howard Gore to supply a need which he felt while preparing a work on the " History of Geodesy." Before proceeding far in that work he found it very difficult at any time to make sure that the literature re- garding the operations of a given period had been exhausted, and he sought to collect titles as well as the works themselves. His purpose extended to making the enterprise useful to others. He went abroad and searched through European libraries, exam- ined minor libraries by proxy, and corre- sponded with authors to find if they had any other works than those of which he had the titles. The outcome of this persevering la- bor is a list filling four hundred columns of references, with short remarks where the title alone is not explanatory enough. Sev- eral institutions, among them the Interna- tional Geodetic Congress of Berlin, offered to publish the book ; but the author thought our Coast and Geodetic Survey was entitled to the preference, and the work is therefore issued under its auspices.

Part I of the nineteenth volume of the " Annals of the Observatory of Harvard Col- lege" contains Meteorological Observations made during the Years 1S40 to 1888 inclu- sive, under the direction of the several di- rectors of the observatory, Profs. W. C. and G. P. Bond, Joseph Winlock, and F. C. Pick- ering. Partial publications of these observa- tions could already be found in the " Mem- oirs " of the American Academy of Arts and Sciences, the " American Almanac," and the Patent-Office Reports, but it has seemed desirable to make a collection of the monthly means. The volume begins with a history of the meteorological work of the observa- tory ; the " monthly and annual results " come next ; after which follow " Observa-

��tions of Aurora Borealis," " Thunder and Lightning," and " Miscellaneous Phenome- na," embracing " temperatures of wells," of " river, rain, and cellar," " Extremes of At- mospheric Pressure or Temperature," " So- lar Ilalos and Parhelia," lunar halos, and " General Remarks." Vol. XX, Part II, of the same series records the Observations made at. the Blue Hill Meteorological Observ- atory, Massachusetts, in 1888, with a state- ment of the local weather predictions, under the direction of A. Lawrence Rotch.

A paper on Domestic Economy in Public Education, by Mrs. Ellen H. Richards, of the Massachusetts Institute of Technology, is published in the series of " Educational Monographs " of the New York College for the Training of Teachers. The success of the manual training system that has been developed out of the carpentry classes for boys has prompted the author to look for a kindred course adapted to the life of girls. She finds it in domestic economy, in which the purposes of sanitary science and hygiene should play an important part. A schedule for a four years' course is introduced. In it cooking "kitchen science" is promi- nent, and this, the author insists, can be placed on a level with the use of workshop tools as a means of mental and physical training. Having mentioned the scientific principles involved in the processes of pre- paring a meal, the author maintains that " the school-girl who has had the elements of chemistry and physics, which are often taught as abstract sciences, summed up and applied to the making of a simple dish, has had her mind awakened to the relations and interdependence of things as no other train- ing now given can awaken it." In an ap- pendix are given summaries of the provis- ions made for teaching domestic economy in several public schools and colleges in the United States and in the girls' schools of the city of Paris. Another number of the same series is an essay on Graphic Methods in Teaching, by diaries Barnard, with an in- troduction by Prof. John F. Woodhull, set- ting forth " Training in Natural Science as an Essential Factor in the Education of the Citizen." Mr. Barnard's essay embodies the relation of experiences in training children to the observation of natural facts and phe- nomena, and to keeping regular records of

��them by means of the graphic system, with specimens of the actual work of certain children in that line. Of the value to the child of thus recording weather observa- tions the author says : " The making of the diagram (printed forms should never be used) is something in the way of mechanical drawing that is a good training for the hand and eye. Secondly, the diagram, being fast- ened upon the wall in some convenient place, becomes a reminder of stated work to be done at a fixed hour a capital training in punctuality, promptness, and precision." Then the thermometer is a tool which the child learns to use. He is induced to go out of doors. Pride is taken in the work as it goes on, developing a regular course. It is instructive and a useful exercise in neat- ness and accuracy, and when it is done " the child has two graphic statements of real phenomena in nature observed by himself and so recorded that at the end the entire work of the month is plainly seen."

The Globe, a New Quarterly Review of World-Literature, Society, Religion, Art, and Politics, of which we have the first number, October to December, 1889, is projected by William Henry Thome, in Chicago, to be a " first-class literary review," which he be- lieves we have not ; and he aspires " to edit and publish something better, broader, stronger, and more cosmopolitan " than any existing American periodical. After a care- ful inspection of his work we are forced to say with regret that he has not reached the object of his aspiration, and that the want he describes, if it existed before, is still un- supplied. The initial number of The Globe contains articles on " The Fuss about Bruno," " The English, French, and American Stage," " The Heroic and Commonplace in Art," " Emerson and his Biographers," " Socialism and Poetic Retribution," " Dr. McCosh and Modern Philosophy," etc.

Edenic Diet, the Philosophy of Eating for the Physical and Mental Man (Isaac B. Rumford, Santa Cruz, Cal., 25 cents), is in- tended primarily to exalt an exclusive vege- table diet and furnish recipes involving its principles. To this are added a mass of rhapsodical matter and a scheme for " an Edenic home " which those may enjoy to whose mode of thought they are adapted.

Mr. J. Madison Cutts, of Washington,

�� � has published, as especially pertinent to the times, an address by the late Stephen A. Douglas on An American Continental Commercial Union or Alliance. It is, he says, the last paper written by the distinguished statesman, and has not been published before. It was prepared after seven of the Southern States had gone through the form of seceding, and was intended to serve as one of Mr. Douglas's immediate plans to promote the future welfare of the country in case a reconciliation and restoration were effected. Besides its interest as the last thought of one of the most distinguished statesmen of the period before the war, the address is pertinent on account of its direct bearing on a scheme of national policy which is now under discussion.

In an essay on God and the Universe, Mr. James W. Stillman proposes to consider "the alleged existence of a Supreme Being and the theistic hypothesis of creation." lie is brought to the conclusion that "the whole problem of the existence of God and the origin of the universe is entirely beyond and above the scope of the human intellect"; and there he is content to leave the matter.

In a pamphlet on The Disposal of the Dead, Dr. John M. Peacocke, of Brooklyn, after considering other methods, suggests desiccation, which was practiced by the ancient Peruvians, as in many respects the preferable one.

Questions for Debate in politics and economics is the latest publication (No. XXVIII) of the Society for Political Education, 330 Pearl Street, New York.
