The Common Sense of the Exact Sciences. By William Kingdon Clifford. With One Hundred Illustrations. New York: D. Appleton & Co. Pp. 271. Price, $1.50.
Professor Clifford was applied to in 1871 to prepare a volume for the "International Scientific Series." He was asked if he would undertake a book to be entitled "Mathematics for the Non-Mathematical," the object of which should be to find out how far it is possible to go in explaining mathematical ideas to persons of intelligence who have had none of the higher mathematical training. This idea had been before proposed to several mathematicians, who agreed that nothing could be made of it; but it was suggested that if anything could be done with it Clifford's was the genius to do it. Professor Clifford was struck with the idea as novel and interesting, and said he would make a study of it and see what it promised. The result was so favorable that he decided to undertake the book and give such attention to it as his slender health and various pre-engagements would allow. There was but little doubt that the project was eminently suited to the peculiar characteristics of Clifford's mind; and that the subject was certain to be handled by him with originality and result in a valuable contribution to mathematical literature. But it soon became apparent that there was a serious question about the possibility of his accomplishing the task at all, on account of his declining health. He, however, did considerable work on it, but left it in an unfinished and fragmentary condition at his death in 1879.
In arranging the plan of the work it was Professor Clifford's intention to treat the fundamental conceptions of mathematics in six parts or chapters under the heads of Number, Space, Quantity, Position, Motion, and Mass. Of these six subjects he dealt with but four, dictating the chapters on Number and Space completely, the first portion of the chapter on Quantity, and nearly the entire chapter on Motion. Shortly before his death he expressed a wish that the book should only be published after very careful revision; that the title, The First Principles of the Mathematical Sciences explained to the Non-Mathematical, should be abandoned, and that the volume should be entitled The Common Sense of the Exact Sciences.
It was not easy to find a mathematician who would undertake to finish Professor Clifford's work. Upon his death, Professor Rowe, of University College, engaged to do it; but he also died before accomplishing the task, so that the final revision had to be made by still another hand. There are parts of this work contributed by Professor Clifford which answer finely to the original idea of it, and show what might have been done if he had lived and adhered to the first conception. A mistake was made by the subsequent editors in seeking to finish the work as they thought Clifford would have done it, rather than as in their judgment it might seem best. As it is, the work will probably be found more attractive to mathematicians than to non-mathematicians.
Annals of the Astronomical Observatory of Harvard College. Vol. XIV. Parts I and II. Observations with the Meridian Photometer during the Years 1879-'82. By Edward C. Pickering, Director, aided by Arthur Searle and Oliver C. Wendell. Cambridge: John Wilson & Son, University Press. 1885.
Almost the earliest record we have of astronomical observation is the catalogue of 1 ,028 fixed stars in the "Almagest" of Ptolemy, the epoch of which is a. d. 138. The chief value of this catalogue consists in its classification of the stars into six magnitudes, which classification, so far as those stars which are visible to the naked eye are concerned, has been continued to the present day. Since that time many other astronomers have made systematic observations on the relative brightness of the stars, the comparisons up to the present century having been made either by the naked eye, or with the assistance of an opera-glass only. About the middle of this century photometers specially adapted for comparing the light of the stars were first used by German astronomers. Zollner invented a photometer, consisting of a telescope in which the light from a kerosene-lamp, admitted through a very small hole and presenting the appearance of a star, is compared with the real star under observation. C. S. Pierce, of the United States Coast Survey, used such a one in the construction of a photometric catalogue of 494 stars, published in Vol. IX of the "Annals of Harvard College Observatory." His description of his difficulties with this very imperfectly contrived and still more imperfectly constructed instrument would be amusing, if it did not excite regret that so accurate an observer and excellent a mathematician should have been weighted with an instrument so poorly adapted to the work.
Up to within a few years, only about 500 stars had been the subject of photometric observation, and for some time it has been regarded as highly desirable that systematic comparisons should be made of the light of all stars visible to the naked eye.
In Vol. XIV of the "Annals of the Observatory of Harvard College" we have the records of the most extensive and complete photometric observations ever undertaken. The great attention which Professor Pickering, the director of the observatory, has given to astro-photometry, and the large experience he has had with photometers, both of his own and others' construction, peculiarly fitted him for such a task.
Part I of the "Annals" opens with a description of the meridian photometer devised by Professor Pickering. Having ascertained by experiment that any change of position on the part of the observer had an injurious effect upon the observations, he constructed his instrument in the form of a broken transit, in which, the line of sight being always horizontal, stars at all altitudes could be observed without moving the head. Experience with other photometers had also satisfied him that no artificial light could be a proper standard of comparison for the light of a star. A real star was therefore chosen, and the fact that the pole-star is always visible, and its light, on account of its very slight changes of altitude, a constant quantity, directed him in his choice of it as the standard of comparison for all stars. To make sure that it was otherwise suitable, a large number of observations were made of the pole-star, to ascertain if its light was subject to any periodical variation.
A reliable instrument and perfect standard having been thus obtained, and many preliminaries settled which it is impossible to touch upon here, observations were begun in October, 1879 and continued till September, 1882. During this period seven hundred series of observations were made, including 94,476 separate comparisons, the result being that every star not fainter than the sixth magnitude, between the north pole and thirty degrees of south declination, was compared from three to fourteen times with the pole-star. The whole number of stars thus compared is 4,260.
The space to which this review is necessarily restricted renders it impossible to give even a passing notice to the immense amount of work expended upon the subject of astro-photometry as recorded in these "Annals." An idea can be formed from the statement that there are in all ninety-one tables, some of which occupy several pages. The "General Catalogue," constituting Table XXVII, alone occupies 211 pages, each line having twenty-six columns, one of which has fourteen sub-headings.
Part II of the "Annals," the publication of which has been delayed till the present year, is largely devoted to a discussion of the work of those astronomers, from Ptolemy to the present day, whose estimates of the relative magnitudes of the stars Professor Pickering has chosen for comparison with his own. A very complete list of all known or suspected variable stars is also given, with copious notes as to dates and observers. There is also a chapter on the distribution of the stars.
Professor Pickering does not close his work with the advancement of any theories of his own. But, for whatever purpose an exact determination of the relative magnitudes of the stars may be desired, either for the discovery of variable stars, or to Template:HWS ascertain the position of the sun in the Galactic Cluster, this volume of the "Annals" fills a place which no other work yet published can make any pretense to. Whether we consider the perfection of the instrument employed, the plan of observation pursued, the accuracy and care with which the observations were made, the large number of stars observed, the completeness of the records, or the exhaustive comparisons that have been made of the observations with those of other astronomers, we are equally satisfied that, so far as the photometric observation of all stars visible to the naked eye in northern latitudes is concerned, the work of Professor Pickering and his able assistants leaves nothing to be desired.
The Chemistry of Cookery. By W. Mattieu Williams. New York: D. Appleton & Co. Pp. 328. Price, $1.50.
Since the publication of Johnston's "Chemistry of Common Life," thirty years ago, no book so important has appeared in this line of inquiry as the volume before us. Johnston's work was of broader scope, and, in fact, contributed little to the science of the culinary preparation of foods, to which Williams's work is devoted. Much has been done in this direction in the last generation, and a work was needed embodying the most important practical results. This Professor Williams has now given us in a very satisfactory form. Of the extent and importance of the information conveyed in his pages nothing need be said to the readers of "The Popular Science Monthly," in which the successive articles have appeared; but, now that they are collected together and offered as a treatise on the science of cookery, it is proper to state that the work has been ably done, and is entitled to rank as a standard upon its subject. Mr. Williams has given us "the present state of knowledge" on the chemical changes to which alimentary substances are subjected by customary kitchen operations. His facts and his chemistry are to be relied upon, and his conclusions are generally made with judgment, but some of his speculations may be extreme, and will be received with caution. His work has been criticised as if he had made too much of the test-tube and analytical operations, and built unwarrantably upon their results. There are, of course, many things about organic substances and their subtile changes which chemistry can not explain, and it certainly can not give us a complete science of foods. But the author of the present work is quite aware of this, and we do not think he has unduly strained the resources of his science in his efforts to elucidate the subject. His book will prove invaluable to read, for practical instruction, for reference in using common cook-books, and as a text-book for classes wishing to study the science of cooking in a careful and thorough manner.
A Text-Book of Hygiene. By George H. Rohé, M. D., Professor of Hygiene, College of Physicians and Surgeons, Baltimore. Baltimore: Thomas & Evans. Pp. 324.
Every important division of the subject receives some attention in this treatise. It is intended to present the essential facts upon which the art of preventive medicine is based, in such manner as to form a guide for the American student, practitioner, and sanitary officer. Beginning with general considerations in regard to air, water, food, and soil, the author goes on to the special hygiene of dwellings, hospitals, and schools, and takes up also industrial, military, marine, and prison hygiene. Several chapters are devoted to personal hygiene. Histories of the epidemic diseases are given, and the subjects of disinfectants, quarantine, and vital statistics are also included. A list of special works is given with each chapter. The author makes little claim to originality; the qualities which he has especially sought are comprehensiveness and reliability.
The Microtomist's Vade-Mecum. By Arthur Bolles Lee. Philadelphia: P. Blakiston, Son & Co. Pp. 424. Price, $3.
This work—"a hand-book of the methods of microscopic anatomy"—has been prepared chiefly with the design of furnishing a complete but concise account of all the methods of preparation that have been recommended as useful for the purposes of microscopic anatomy. In order to make it also a suitable guide for beginners, a general introduction has been added, and introductory paragraphs have been prefixed, when needful, to the different chapters, which, taken all together, go far to make up a formal treatise on the art. To furnish to instructed anatomists, for whom the book is primarily designed, information on points of detail as to which their knowledge or memory may be at fault, a collection of formulae is given and a number of special methods are described. For beginners, again, a collection is furnished of examples, which are not intended for imitation, but as hints suggestive of the most fitting processes.
The Diamond Lens, with other Stories. By Fitz-James O'Brien. New York: Charles Scribner's Sons. Pp. 337. Price, paper, 50 cents.
Mr. O'Brien was of Irish birth, a poet and story-writer of bright genius, whose contributions to the newspapers and magazines attracted much attention when they were published, and were generally popular and widely read, showing distinct originality and strong powers of penetration and description; they deserve to be remembered. The present series, including a baker's dozen of the stories, was published in 1881, with a biography of the author, by Mr. William Winter, and now appears again in a second edition.
The Life of Society. By Edmund Woodward Brown. New York: G. P. Putnam's Sons. Pp. 270. Price, $2.
This work is intended to present a general view of the various factors, in nature and man, that work upon the structure and methods of society, and of the influence, in turn, of society upon man. The author's object has been, in a systematic study, to obtain as deep and adequate a general conception of society as possible, "the society of any township or any country of the world to-day, or the whole world of society in the past. . . . I wish," he says, "to find an explanation of society that will suit wherever society is in any country, or has been in any country or age. I want to get a general view of the constant part of every society. I want to evidence and illustrate this by social and historic facts, drawn from the wide range of society in the past or the present." In general, he adds, "I hope, then, I have shown the real foundation of social science, though, doubtless, there are deficiencies." The subject is considered under the head of the effective causes acting upon society, among which arc the influences of the body, man's intellect, man's will, habit and usage, disposition and feeling, etc.; then are considered various features of society, the influence of the parts of society upon one another, and of the whole upon the parts; the growth and progress of society; its incompleteness, imperfection, and deterioration; rhythm and epochs in the life of society; its laws, restraints, liberties, forms, and institutions; and, finally, a general view of the spheres of society. The work bears the marks of laborious thought.
The Limits of Stability of Nebulous Planets, and the Consequences resulting from their Mutual Relations. By Professor Daniel Kirkwood. Pp. 110.
This monograph is an inquiry respecting the extreme limits within which a planet's atmosphere may exist, as measured by the distance from the planet's center, at which gravity and the centrifugal force will be in equilibrium; and further into the original or maximum values of the corresponding distances, which were much greater before the members of the system had contracted to their present dimensions. These found, the author applies the bearing of the answers to the discussion of the question, "Were the planets formed from nebulous rings?"
Third Annual Report of the Ohio Agricultural Experiment Station, for 1884. By William R. Lazenby, Director. Columbus, 0.: Myers Brothers, State Printers. Pp. 240.
The theory of the station, it is stated in the introductory part of the report, "is to tell the farmers of Ohio what they most need to know"; and much of the matter in the volume appears to answer to that description. Field experiments were conducted during the year with grasses, fruit, and garden vegetables. The primary object of the tests is to improve upon the best-known methods of cultivation and management. Among practical questions, earnest attention was given to ascertaining the comparative value of the best varieties; the effects of thick and of thin seeding; the effects of sowing or planting at different dates, different distances, and different depths; the value of different methods of manuring and applying fertilizers; and the comparative merits of different systems of culture. In connection with this work chemical analyses were made; experiments were carried on in self-and cross-fertilization; investigations were made in regard to the best treatment of certain insect enemies and plant-diseases; the climatic conditions were carefully noted; and the work begun in practical forest-tree culture was extended. The results of the investigations are intelligently and intelligibly described. We regard the document as a good specimen of what such a report should be.
An Introduction to the Study of the Compounds of Carbon; or, Organic Chemistry. By Ira Remsen, Professor of Chemistry in the Johns Hopkins University. Boston: Ginn, Heath & Co. Pp. 364. Price, $1.30.
The arrangement of this book is somewhat different from that commonly adopted by teachers of organic chemistry. The lowest two members of the paraffin series are first considered, then, in order, their halogen, oxygen, sulphur, and nitrogen derivatives, and after these any peculiarities of higher paraffins and of their derivatives. Fifty pages are devoted to compounds which are at the same time alcohols and acids or aldehydes, etc. Next some account is given of the series of hydrocarbons homologous with the paraffins, and of their derivatives. The benzene series follows, and the various modifications and combinations of the ring molecule are described. Only the more important compounds in each group, and the more important reactions, receive attention. General directions are given for eighty-two experiments, a fair proportion of which the author advises each student to perform; for details in regard to analysis, etc., larger works are to be consulted. The author has taken pains to make the student see for himself the reasons for adopting the prevalent views in regard to the structure of the compounds of carbon, and has aimed to give a general view of the whole field, leaving minute descriptions to the chemical dictionaries. The book is a welcome addition to the unsatisfactory list of text-books in organic chemistry.
A Reprint of Annual Reports and other Papers, on the Geology of the Virginias. By the late William Barton Rogers. New York: D. Appleton & Co. Pp. 832. With Maps.
This republication is made in answer to requests by geologists and others for the reports, which have been several years out of print, or very rare. "Of the value of the scientific discoveries, the generalizations, and the descriptions of the geological formations contained in these reports," says the editor, "there can be no better evidence than the frequency with which they are referred to and quoted by all who are engaged in exploring the geology of the Virginias, and the aid they have given to the development of the industrial resources of these States, which they foreshadowed, and in fact often clearly pointed out, at a time when the geology of the State was unexplored." The reports are arranged substantially in the order in which they were made, with the preliminary correspondence and the arguments addressed to the Legislature for the continuance of the appropriations, so that they have an historical as well as scientific value. The author himself desired to condense and codify the reports, and present them with his special map and sections, as a single whole, but time and opportunity never came for doing so. Thus, the editor's work has been simply to revise the reproduction of the original reports and maps. But a number of papers additional to the reports, relating to the geology of the Virginias, have 'been embodied in the volume.
An Introduction to Practical Chemistry, including Analysis. By John E. Bowman, F. C. S. Edited by Charles L. Bloxam, F. C. S. Eighth edition. Philadelphia: P. Blakiston, Son & Co. Pp. 248. Price, $2.
In this manual is laid out a short course of laboratory work, beginning with general chemistry, and including something of both qualitative and quantitative analysis. The book has been made especially for college students who have not studied chemistry, and have time only to gain some familiarity with chemical operations, without devoting much attention to chemical philosophy. The author has avoided the use of complicated or expensive apparatus, and has aimed to give clear and full explanatory details of the several processes. Quantities are given in English measures, followed by metric equivalents. In the part devoted to analysis are included blow-pipe tests and determinations of specific gravity. Several new examples of quantitative separation have been added in this edition, and volumetric analysis has been given a separate chapter. Ninety cuts illustrate the operations described. A dozen pages of technical information in regard to reagents are given, also tables of weights and measures, reactions, and solubilities, lists of salts for blow-pipe examination, etc. The uncut edges of the volume are rather inconsistent with the title, "Practical Chemistry."
The Fallacy of the Present Theory of Sound. By Henry A. Mott, Ph. D, New York (printed for the author): John Wiley & Sons. Pp. 103. Price, 50 cents.
We are informed on page 7 of this book that "in 1877 Dr. H. Wilford Hall published a work on the 'Evolution of Sound,' in which he carefully considered, step by step, the present undulatory theory of sound, as elucidated by the distinguished authorities." It is furthermore said that Dr. Hall has shown that the current acoustical theory contains numerous fallacies, and, from the language adopted throughout the book, we should infer that it is shown to be childish, absurd, and wholly unworthy of credence. Dr. Mott avows his agreement with Dr. Hall, and he gave a lecture before the New York Academy of Sciences, December 8, 1884, stating Dr. Hall's objections to the present theory of sound, and this lecture constitutes the volume before us. Dr. Mott says that the work of exploding this theory has already been pretty well accomplished, and in his preface he gives the names of divers presidents of colleges, and professors thereof, from California to New Hampshire and South America, who have accepted "Dr. Hall's discovery," and abandoned as baseless and worthless the hitherto accepted wave theory of sound.
We can not here state Dr. Hall's case as re-expounded by Dr. Mott, but discharge our duty by informing all who are concerned about it where they can get instruction upon the subject. Nor have we formed any opinion, from having examined the arguments, whether the wave theory of sound has been exploded or not. There is getting to be such a free use of dynamite in these latter days among the supposed fundamentals and essentials of science, and long-established opinions seem so liable to sudden overthrow, that we are losing our interest in the operations. Perhaps the safest rule to follow in these revolutionary circumstances is to abide by long-tested principles until given up by those longest and most profoundly trained in the work of scientific investigation.
School Bulletin Year-Book of the State of New York, for 1885. By C. W. Bardeen. Syracuse, N. Y.: C. W. Bardecn. Pp. 160.
The "Year-Book" is intended to serve as a convenient educational directory for the State of New York. It contains sketches of the county superintendents and county commissioners, and a list of the principals of village schools and academies arranged by counties. Every alternate leaf is left blank, for the insertion of notes, additions, and corrections.
Obiter Dicta. New York: Charles Scribner's Sons. Pp. 232.
This is a collection of essays, which may be called critical or discursive, according to the mood of the reader, on "Carlyle," "Mr. Browning's Poetry," "Truth-Hunting," "Actors," "A Rogue's Memoirs," "The Via Media," and "Falstaff." They embody the "gratuitous opinions" of one who seems to be an independent thinker, forcibly and often very pungently expressed. Each essay has its own quality; that on "Falstaff" is a fund of humor; and they are all pleasant reading.
The Sun and his Phenomena. By the Rev. T. W. Webb. New York: industrial Publication Company. Pp. 80. Price, 40 cents.
Notwithstanding the multiplicity of popular treatises on astronomy, the author has thought there might still be room for a description of the sun, which, confining itself to a brief but careful enumeration of its phenomena, may be found serviceable in elementary instruction. The most recent discoveries are taken notice of.
A Catalogue of Chemical Periodicals. By H. Carrington Bolton, Ph. D., Professor of Chemistry, Trinity College, Hartford, Conn. Reprint from Annals New York Academy of Sciences. 1885. Pp. 58, 8vo.
This bibliography contains the titles of the chief chemical periodicals of all countries, from the rise of this literature to the end of 1884. The titles number 182, and eight languages occur; the arrangement is strictly alphabetical by the first word; cross references are freely introduced, from the editors' names to the journals published by them, and from the chemical societies to their publications. Bibliographical details are quite full; the different titles borne by a periodical at different periods are arranged in chronological order under the first or earliest title. At the end of the paper is a geographical index, arranged by countries and cities.
The material for this bibliography has been drawn for the most part from a larger "Catalogue of Scientific and Technical Periodicals—1665-1882," by the same author. The larger comprises, we understand, over 5,000 titles, and forms a volume of nearly 800 pages; it will be published by the Smithsonian Institution in a few weeks.
The present catalogue will be useful to chemists, and especially to librarians.
Bulletin of the Philosophical Society of Washington. Vol. VII. 1884. Washington, D. C.: Judd & Detweiler. Pp. 135.
This volume contains the minutes of the society and of its mathematical section for 1884. The society continues to show a vigorous growth. The total number of members enrolled, from the beginning in 1871, is 292. Thirty-five new members were added during the year, and the present number of active members is 173. The annual address of the president, James C. Welling, delivered December 6, 1884, was on "The Atomic Philosophy, Physical and Metaphysical." The "Minutes" include, besides this address in full, abstracts of the papers read at the stated meetings of the society, among which we notice, as of current general interest, Mr. Russell's on "The Existing Glaciers of the High Sierra of California," Mr. Kerr's on "The Mica-Mines of North Carolina," Mr. Russell's on the "Volcanic Dust of the Great Basin," Mr. Dall's on the "Volcanic Sand that fell at Unalaska in 1883," with Mr. Diller's on the composition of that dust; and Mr. Dutton's on "The Volcanoes and Lava-Fields of New Mexico."
How should I pronounce? Or, the Art of Correct Pronunciation. By William Henry P. Phyfe. New York: G. P. Putnam's Sons. Pp. 305. Price, $1.25.
The author assumes that the subject of English pronunciation has not, as yet, had its main facts and principles clearly and concisely presented; and that, among existing books, none consider the question embraced in the title of the present one in its broadest sense, and endeavor to give it an intelligent and satisfactory answer. His effort has been to supply this lack; to furnish the reasons for the directions given, and to indicate the means of becoming proficient in the very important art. After an introductory chapter presenting general views and principles, the topics are considered of the physical nature of sound, the nature and use of the vocal organs, articulate sounds, the sounds of the English language, alphabets, and the English alphabet. The last topic is followed by complete lists of the various sounds for which each letter in the English alphabet stands, and of the various symbols used for each elementary sound, which are claimed to be the fullest that have ever appeared. Then come rules and suggestions for becoming proficient in English pronunciation and the indication of the correct pronunciations, according to both Webster and Worcester, of more than one thousand words that are frequently mispronounced. Proper names are considered in another chapter, and a bibliography of the subject is given in an appendix.
The Lenapé Stone: or, the Indian and the Mammoth. By H. C. Mercer. New York: G. P. Putnam's Sons. Pp. 95. Price, $1.25.
In 1872 a young farmer in Bucks County, Pennsylvania, turned up in plowing a "queer" stone, which he took home and threw into a box with his other "Indian curiosities." It was a piece of a broken "gorget-stone," on which could be discerned carved lines, describing the outline of a mammoth. In 1881 he sold it in a lump with his other specimens to Mr. James Paxon, for the round sum of $2.50. Shortly afterward, a smaller fragment was found, which, joined to the former one, completed the gorget, and also the design of a party of Indians hunting a mammoth. The question necessarily arises, Is the stone with its tracings a genuine aboriginal relic? It is a very important one in American archaeology. There appears no reason to doubt the entire honesty of all the persons who arc known to have handled the specimen. Unfortunately, the stone itself is not capable of giving evidence; for it was not seen, scientifically, till it had been cleaned two or three times, and its possessors had scratched over the lines to make them plainer. Its occurrence where it was discovered is unaccountable if it is not genuine. It has been submitted to experts in aboriginal relics, and they have expressed different opinions respecting it. Three other carved stones have very recently been found on the same farm, the examination of which and their comparison with this one may throw some light on the subject. Mr. Mercer presents the evidence on both sides with seeming impartiality, but evidently believes in the genuineness of the stone.
