Chemical Exercises in Qualitative Analysis. For Ordinary Schools. By George W. Rains, M.D., Professor of Chemistry in the University of Georgia, New York: D. Appleton & Co. Pp. 59. Price, 50 cents.
Under this modest title, and within very moderate limits, Professor Rains has made a very considerable contribution to sound scientific education. He has had much experience in introducing boys into chemistry, and the course of exercises here worked out he has long verified in practice. His object is to bring the minds of pupils into immediate contact with Nature, and so he puts them at work, at the outset, to find out by trial the chemical properties of substances. His little book provides for no recitations, but for elementary chemical work. The learner is not told; he finds out the properties and reactions of bodies by testing them and by experiment. His progress consists in solving problems, and making what are to him a course of new discoveries. The book is based upon the idea that mere book-knowledge in chemistry is a sham and an imposture.
To facilitate the mode of study adopted, Professor Rains has devised an ingenious and most convenient portable laboratory, to which his manual is adapted, and which will be a great help to students, whether working alone or in school-classes under a teacher. We will give a drawing next month of this useful contrivance, and describe Professor Rains's method more fully.
Henry's Contribution to the Electro-Magnetic Telegraph. With an Account of the Origin and Development of Professor Morse's Invention. By William B. Taylor. Reprinted from the Smithsonian Report for 1878. Washington: Government Printing-Office. 1879.
The name of Professor Henry is not among those who are associated in the popular mind with the electric telegraph, and yet without his discoveries the electro-magnetic telegraph of to-day could not exist. Though, in making his electric investigations, he was not working with the aim to construct a telegraph, he yet clearly perceived the bearing of his results upon such a system of communication. The telegraph has been a growth to which many minds contributed, and it is desirable that the labors of each of the contributors should be placed in such relations as to show their comparative value. This Professor Taylor has done in the above pamphlet, in which the remarkable investigations of Professor Henry receive a recognition that their importance deserves. Professor Taylor reviews the attempts to operate a telegraph by frictional electricity, then by galvanism, by galvano-magnetism, and finally by means of the electro-magnet. Professor Taylor thus states the contribution of Professor Henry to the solution of the problem: He has, he says, "the preëminent claim to popular gratitude of having first practically worked out the differing functions of two entirely different kinds of electro-magnet: the one surrounded with numerous coils of no great length, designated by him the 'quantity' magnet, the other surrounded with a continuous coil of very great length, designated by him the 'intensity' magnet. The former and more powerful system, least affected by an 'intensity' battery of many pairs, was shown to be most responsive to a single galvanic element: the latter and feebler system, least influenced by a single pair, was shown to be most excited by a battery of numerous elements; but at the same time was shown to have the singular capability (never before suspected nor imagined) of subtile excitation from a distant source. Here for the first time is experimentally established the important principle that there must be a proportion between the aggregate internal resistance of the battery and the whole external resistance of the conjunctive wire or conducting circuit; with the very important practical consequence that, by combining with an 'intensity' magnet of a single extended fine coil an 'intensity' battery of many small pairs, its electro-motive force enables a very long conductor to be employed without sensible diminution of the effect." These investigations of Henry were made from 1829 to 1831. They made the magnetic telegraph, which the English physicist, Barlow, noticing the rapid diminution in the intensity of the cur- rent, had some years before declared im- practicable, possible. All later inventors and investigators in telegraphy have had to build upon these investigations. Professor Taylor, in reviewing the work of Morse, points out that he was greatly delayed in his work and committed many errors from ignorance of the existing state of electrical knowledge, and especially because of his ignorance of the labors of Professor Henry. He further points out that the work for which Morse gets credit is, in all its more important features, the work of another man Alfred Vail, who, with Dr. Gale, was associated with Morse in perfecting the in- vention. Professor Taylor states that the Morse alphabet and the instrument that was found in practice to work it were both the sole invention of Mr. Vail. The pamphlet will be found an interesting review of this important invention, containing much hith- erto unpublished, and giving such recogni- tion of the labors of those contributing to it as their importance deserves. Professor Taylor was for many years connected with the Patent Office, and has therefore had ex- cellent opportunities of informing himself on the subject.
History of Political Economy in Er- rope. By Jerome-Adolphe Blanqui. Translated from the fourth French edi- tion, by Emily J. Leonard. With a Preface bv David A. Wells. New York: G." P. Putnam's Sons. 1880. Pp. 562. Price, $3.50. This is the first appearance in English of the celebrated work of the French econo- mist Blanqui. It is somewhat remarkable that a translation has not before been made, as there is no English work covering the same ground, and as M. Blanqui has suc- ceeded in putting in a moderate compass a large amount of information concerning economic theory and practice, and putting it, moreover, in a way that will prove very attractive to the general reader. Though it is more than forty years since the book was first published, it has lost little or none of its interest for the present, and its trans- lator has conferred a favor upon the public by her excellent rendering of the original. .M. Blanqui was the pupil of J. B. Say, and, on the death of that economist in VOL. xvii J8 1833, he succeeded him in the professor- ship of Political Economy in the Conserva- tory of Arts and Trades. In his discussion of social and economic questions, the hu- manitarian element is predominant, and the great value of political economy to him was that it consisted of a body of most benefi- cent truths which held out the promise and pointed the way to an increasing betterment of the condition of all classes. He had, therefore, a warm interest in all questions concerning the improvement of the indus- trial classes, and regarded with sympathy the various schemes, rife in his time, for
furthering their welfare.
With great ad-
miration for the school of English econo- mists, and according to them the honor of placing the science upon a true foundation, he yet protested that their formulas were too rigid, and that they had not taken ac- count of the grain of truth that, along with many vagaries, was to be found in the doc- trines of various social sects.
In his view, political economy did not begin when men first carefully studied the phenomena of wealth, and endeavored to elaborate a body of doctrine, but it began much earlier. Men became political econo- mists when they began to exchange the products of their labor, and when they com- menced to exercise foresight in providing for their material needs. Since then eco- nomic phenomena, as well as the theories held concerning them, have slowly ad- vanced the one in complexity and varie- ty, the other in a more perfect comprehen- sion of the relations of the facts. M. Blan- qui therefore begins his work with a con- sideration of the political economy of the Greeks and Romans, and traces it onward through the middle ages to the time at which he wrote. In this survey he notices the importance attached by the Greeks to financial matters, the contempt of the Ro- mans for labor and commerce, the influence of Christianity, which he says changed the basis of civilization from slavery to free- dom, the change impressed on European life by the influx of barbarians, the rise of the feudal system, and the influence of the Crusades in giving an impetus to commerce. In considering the rise of credit and the in- stitution of banks, he points out the value of the services of the Jews, to whom finance owes so much. Modern commerce properly begins with the rise of the Italian commercial cities, and thence onward it moves steadily if slowly. Its theory is the mercantile system. Nations only grow rich by despoiling each other, and money is alone riches. This theory, once universal, has not even yet disappeared. It has survived the clearest demonstrations of its falsity, and influences to-day much of the speculation and legis- lation upon economical matters. The first important school to combat it, and to lead the way to a true theory of wealth, was that of the Economists, which arose in France just after the disastrous failure of Law's scheme. Quesnay was one of its founders and most distinguished represen- tatives. It found prepared for it a soil in which it readily took root and flourished. Law's failure had produced an entire re- vulsion in French sentiment. " People," says M. Blanqui, " had for some time deemed money to be wealth in an especial sense; . . . there were henceforth no true riches but land." The Economists came preaching this doctrine. To them agriculture was the only productive occu- pation. " Manufacturers, traders, work- men, were all paid clerks of agriculture, which was the sovereign creator and dis- penser of all wealth." Landed proprie- tors were rightly preeminent over all other classes. They reaped all wealth; they should, therefore, pay all taxes. Hence the Economists would have but one tax that upon land. And the same reasoning led them to entire freedom of trade. Able men rallied to the support of the new views, and there gradually grew up a body of statesmen imbued with them, one of whom, Turgot, was to attempt to carry their for- mulas into practice.
The Economists were mistaken. They failed to see that wealth can be created by labor; they were blinded by their doc- trine of the importance of land, but they have rendered great service. " Their books are forgotten; but their doctrines have germinated like a good seed, and the pre- cepts which they taught have made the cir- cuit of the world, freed the industrial arts, restored agriculture, and prepared the way for commercial liberty." It was reserved for Adam Smith to see clearly what the Economists saw dimly, to correct their errors
by a true analysis of the phenomena of wealth, and to place economics on an en- during foundation. He restored to labor the position of a creator of wealth denied it by the Economists, and he first pointed out clearly the results of the division of labor. He placed commercial liberty upon an impregnable basis, and showed how pri- vate interest freed from restrictions works for the best welfare of the individual and society. Great as was his genius, " Adam Smith did not, however, have the honor of creating political economy at a single stroke "; but he laid the foundation upon which his successors securely built. The Economists had given to land too prominent a place; he gave it to labor. This his fol- lowers corrected: they adjusted the parts, recognized the place of capital, and devel- oped the science symmetrically. But they all failed to recognize sufficiently the wel- fare of the worker. They all regarded him too exclusively in the light of an economic machine for the production of wealth. This error the economists of the French school have corrected. They have insisted that the value of increase of wealth is to be un- ceasingly judged by what it brings to the workers, and they withhold their admiration if the thing it brings be not good: " We are to-day obliged to seek a regulator, and to put a curb on those gigantic instruments of pro- duction which feed and which starve men, which clothe and which despoil them, which relieve and which crush them. The question is no longer, as in the time of Smith, exclu- sively that of accelerating production: the latter must henceforth be governed and re- stricted within wise limits. The question is no longer of absolute wealth, but of rela- tive wealth; humanity demands that masses of men who will not profit thereby be no longer sacrificed to the progress of public opulence. Thus decree the eternal laws of justice and morality, too long disregarded in the social distribution of the profits and the labors; and we will no longer consent to give the name of wealth save to the sum of the national product equitably distributed between all the producers. Such is the French school of political economy to which we profess to belong, and its ideas will make the circuit of the world."
The above will, perhaps, give some idea of the general spirit and drift of M. Blanqui's work in viewing social questions, but no one at all interested in such questions will fail to read one of the most fascinating economic works ever published.
A Practical Treatise on Nervous Ex- haustion; its Symptoms, Nature, Se- quences, Treatment. Bv George M. Beard, A.M., M.D. New. York: Wil- liam Wood & Co. Pp. 198.
Dr. Beard's work deals not only with a very important subject to which he has paid long professional attention, but to a subject of prominent and painful interest in this country. Nervous exhaustion, or, as he names it, Neurasthenia, he declares to be at once the most frequent, the most interest- ing, and most neglected disease of modern times; while the family of disorders that have been hitherto grouped together under the name of "general debility," "nervous prostration," " nervous debility," " spinal weakness," "spinal irritation," etc., are of comparatively recent development and abound especially in the Northern and East- ern parts of the United States. The author thus states his purpose in the preparation of the book: " To describe with thoroughness if not exhaustively the symptoms of neura- sthenia those hitherto assigned to the other affections or regarded as special and dis- tinct diseases themselves; to show their re- lation and interdependence; to distinguish them from the oftentimes closely resembling symptoms of organic disease on the one hand, and the symptoms of hysteria and hypochondria on the other hand; to unify and harmonize the complex developments and manifestations of this malady; to indi- cate its pathology and rationale, and. trace out in detail its prognosis, sequences, treat- ment, and hygiene this is the task I have undertaken in the present volume."
Dr. Beard affirms that there has been a very important progress in the treatment of these affections during the last ten years. " In no department of therapeutics has there been even in this most active age so rapid and successful advance as in the manage- ment of nervous exhaustion, and the diseases that result from and are related to it; and hence a subject, the interest of which was originally scientific and philosophic, is now of direct practical and personal concern not only to specialists in the diseases of the
nervous system, but to practitioners and to sufferers everywhere."
As the work is chiefly practical and de- signed for the use of the medical profes- sion in treating the disease as it is found, the question of the causes which lead to it is not taken up. This is a very important branch of the subject, which requires to be itself separately and fully dealt with. Dr. Beard accordingly has in preparation and nearly completed a work on American ner- vousness, intended to be supplementary to the present treatise, which will discuss both the causes and the consequences of the rise and increase of neurasthenia, and the gen- eral nerve sensitiveness which is a kindred phenomenon in this artificial and excitable age. The author remarks that a philosophic and thorough analysis of American nervous- ness must be a contribution to sociology in- volving many problems of race, climate, in- stitutions, and social customs.
Science Primers: Introductory. Bv Pro- fessor T. II. Huxley. New York: D. Appleton ic Co. 18 SO. Pp. 94. Price, 45 cents.
The appearance of this little volume has been waited for with eager interest aud much impatience, owing to the popularity of the science series, to which it is a step- ping-stone, and to the celebrity of its au- thor. Much was expected, and the general expectations will not be disappointed. In the happy selection of its subjects, in the felicity of its illustrations, in the admirable clearness and simplicity of its style, and in the instructiveness of the lessons it incul- cates, Professor Huxley's Primer is quite unrivaled, and it will be read by thousands with equal pleasure and advantage. It aims to convey a general idea of the nature and importance of scientific knowledge, to ex- plain science as a method of thinking, to show its practical uses, and to exemplify its systematic bearings and various aspects by means of the most familiar objects. The first division of twenty pages, under the head of "Nature and Science," treats of Causes and Effects, the Properties and Powers of Bodies, what is meant by the Order of Na- ture and the Laws of Nature, and how sci- entific knowledge is obtained. The second division is devoted to " Material Objects," and sixty pages are given to Mineral Bodies. Water is chosen as a representative natural object, and its remarkable properties are explained step by step, so as to bring out the fundamental physical principles involved in the three states of matter. Ten pages are then given to the properties of Living Bodies, and the Primer closes with a few observations on immaterial objects.
We refer elsewhere to the series of works to which this book belongs, with a view of guarding against their miseinploy- ment in schools.
Health and Health Resorts. By John Wilson, M. D. Philadelphia: Porter & Coates.
Dr. Wilson is of the opinion that many erroneous notions prevail among the Ameri- cans as to the value of health resorts, espe- cially those of foreign countries, and he has therefore in this work undertaken to state the value of such places and the conditions that must be fulfilled as to diet, treatment, etc., in order to obtain their benefits. After a short consideration of health and disease, he considers the general principles of regi- men for invalids at health-stations, and the therapeutical action of mineral waters, their use and abuse, and the value of baths. He also considers the best winter-stations for consumptives and a number of the foreign mineral springs. Dr. Wilson insists that it is not necessary to go away from this coun- try to get all the advantages of foreign springs, as there is scarcely one of these that has not its counterpart in this country.
Memorandum in regard to Instruction in the Mechanic Arts. By Edward At- kinson. Prepared at the Request of the Committee on Prisons of the Massachu- setts Legislature.
In this memorandum Mr. Atkinson urges the adoption of such a course of instruction with actual practice in workshops, in the reformatory institutions of the State, as has been carried on for some years in the Massa- chusetts Institute of Technology. The suc- cess of this system has been so gratifying at this institute that Mr. Atkinson believes it can not but be of great value in prisons and reformatories. He submits a plan of a workshop to accommodate four hundred
pupils, and arranged to give instruction in carpentry, blacksmithing, foundry-work, vise-work, brazing, wood- and metal-working and finishing. The only objection Mr. At- kinson finds to his plan is in the fact that graduates of such reformatories will be much better qualified to earn a living than most of the graduates of the common, and some of the graduates of the higher, institutions of learning.
The Cotton-Worm. By Charles V. Riley, M. A., Ph. D. Washington: Govern- ment Printing-Office. 1880.
This is the third bulletin issued by the United States Entomological Commission, and is devoted to a summary of the natural history of the cotton-worm, with an account of its enemies and the best means of con- trolling it. Illustrations are given of the worm and its enemies, as well as of the various machines designed to be used in exterminating it. Much valuable informa- tion will be found in it of service to the planter, both as to the peculiarities of the worm, and on the best means of protection. The bulletin is sent to those desiring it, upon application to Washington.
A Subject-Index to the Publications of the United States Natal Observa- tory from 1845 to 1875. By Edward S. Holden. Washington: Government Printing-Office. 1879.
Professor Holden states that the twen- ty-two volumes issued from this observatory from 1845 to 1875 contain, on the average, five hundred pages each of valuable obser- vations and discussions, which it is desirable should be easily accessible. He has, there- fore, undertaken this very excellent index. It is in the form of a quarto, of seventy-two pages, in paper binding.
Report on the Lands of the Arid Re- gions of the United States. With Maps. By J. W. Powell. Second edi- tion. Washington: Government Print- ing-Office. 1879.
In the first three chapters of this volume Major Powell treats of the physical charac- teristics of the arid regions of the United States, and the rainfall of the Western por- tions of the country. Mr. G. R. Gilbert has four chapters on the water-supply, on irrigable lands, and on the physical features of the lands of Utah. There is also a paper by Captain C. E. Dutton on the irrigable lands of the valley of the Frazer River; and one by Professor A. H. Thompson on the irrigable lands of that portion of Utah drained by the Colorado River and its tribu- taries. The concluding chapter of the vol- ume, by Willis Drummond, Jr., discusses the question of land grants as aids to internal improvement. The interest and value of the report are shown by the fact that the first edition was soon exhausted, and a sec- ond one called for.
Studies in Fermentation; the Diseases of Beer; their Causes and the Means of preventing Them. By L. Pasteur, Member of the Institute of France, the Royal Society of London, etc. Trans- lated by Frank Faulkner and D. Con- stable Robbe. Macmillan & Co. Pp. 418. Price, $6.50.
There are but few subjects that would seem less attractive than the scientific in- vestigation of ferments and the processes of fermentation, yet the book before us is alive with interest from beginning to end. This is due to the genius of the author, the scientific importance of his inquiry, the spirited controversies which have recently grown out of the inquiry, and its important practical results. Pasteur is a man re- markably endowed for subtile research. His investigation of the diseases of the silk- worm was one of the most difficult, refined, and successful of modern researches. A delicate experimenter, a sharp observer, and a man of keen insight and careful judg- ment, he has taken the acknowledged lead in investigating the obscure phenomena of microscopic life at the present time. The questions opened are the deepest in modern thought, involving nothing less than the origin of life-forms, and the method of Na- ture regarding vital phenomena. Pasteur has been in the center of the battle of spon- taneous generation, and yet so practical have been his investigations that the brew- ers are of all men most interested in them. The present work deals with the diseases of beer, and those deteriorations of its processes that are involved in the changes of fermen- tation; and its leading translator is an au- thor of the " Art of Brewing." The work
will be of great interest, therefore, to all engaged in this branch of manufacturing in- dustry, not only by throwing light upon the theory of brewing, but by the solutions it gives of serious practical difficulties hither- to encountered in the brewer's art. Pas- teur's elucidations of fermentative action bear also upon the operations of wine-mak- ing and vinegar-making, as well as beer- making.
A Text-Book of Physiology. By M. Fos- ter, M. A., M. D., F. R. S., Pra3lector in Physiology and Fellow of Trinity Col- lege, Cambridge. With Illustrations. Macmillan & Co. Pp. 720. Price, $3.50.
The writing of his " Physiology " by Dr. Foster was far from being a case of book- making in the ordinary sense. He is a man not only devoted to his subject, but espe- cially and assiduously devoted to its prog- ress, so that the preparation of his text- book was but an incident in his studies, and has, moreover, been a continuous work with him for several years. The third edi- tion, revised and enlarged, is now issued; and it represents, perhaps, better than any other book the recent advance and present condition of physiological science. Dr. Fos- ter is at the head of the new physiological laboratory at Cambridge, England, where the experimental method of physiological in- quiry is vigorously pursued; and his text- book is, of course, prepared from that point of view. Under this method, physiological science is slowly acquiring certainty and in- creasing precision in its conclusions, as no one can fail to see who compares Dr. Foster's text-book with the standard treatises of a few years ago. We agree with Professor Burt Wilder that this is " in some respects the best physiology in the English language." We note that a cheap students' edition of the work is to be issued in a short time.
A Forbidden Land; Voyages to the Core a. By Ernest Oppert. With 21 Illustrations and Two Charts. New York: G. P. Putnam's Sons. 1880. Pp. 334. Price, $3.
This is an interesting account of a little known country in Eastern Asia. The pres- ent kingdom of Corea consists of a large peninsula east of the Chinese Empire, ex- tending from 42 north latitude to the Straits of Corea. The country has always been exclusive in its policy, this exclusion extending in later years even to its near neighbors, China and Japan, so that very little has been known of the physical fea- tures of the country or of the habits and character of its people. The country for centuries has been at war with China and Japan, and the scene, of fierce internal feuds, and only latterly has it been able to secure itself against its foreign enemies and unite into one kingdom under one ruler. It has been supposed that the Corean Peninsula was settled from China, but this, Mr. Oppert declares, is an utter mistake. The Coreans differ widely in their customs from the Chi- nese, and do not present the physical ap- pearance to justify such an origin. The upper classes of the Coreans are of a Cau- casian type and the lower of a Mongolian one. The country is destitute of native his- tories, and the people profess to know no- thing of their origin, though some of the aristocratic classes have fabulous accounts of it. The author gives much interesting matter concerning the customs, institutions, and natural features of the country, and feels impatient at its seclusion from the trade of the world, and appears to think a forcible opening of it desirable.
United States Geological and Geographi- cal Survey of Colorado and Adja- cent Territories in 1876. By F. V. Hayden. Washington: Government Printing-Office. 18T8. Tins is the tenth annual report of the survey under the direction of Professor Hayden, and is devoted to the survey com- pleting the work in Colorado and portions of adjacent Territories. The report consists of an account of the work done in the geol- ogy, topography, archaeology and ethnology, and paleontology and zoology of the region. The report has a number of excellent maps, and numerous lithographic plates of the ancient mines examined, and of specimens of the pottery, both ancient and modern, of the natives of the region.
Sunshine and Storm in the East. By Mrs. Brassey. New York: Henry Holt & Co. 1880. Pp. 438. Price, $3.50.
Those who enjoyed Mrs. Brassey's ac- count of her "Voyage in the Sunbeam"
will welcome her present account of her two visits to Cyprus and Constantinople. The book is in the form of a diary, which is not, it seems to us, a very interesting way of presenting the scenes and incidents of travel. The work is profusely illustrated and handsomely printed on heavy calendered paper. The cover strikes us as somewhat flashy, but is designed, we presume to be artistic.
