Methods of Gas Analysis. By Dr. Walthee Hempel. Maemil- 

 lan & Co. 399 p. $1.90. 

 This standard worlj was translated by Professor L. M. Dennis 

 with the personal co-operation of the author. Part I. discusses 

 general methods, including the collection of samples, the use of 

 gas burettes and pipettes, purification of mercury, and absorption 

 apparatus; Part II. deals with special methods for the several ele- 

 mentary and compound gases; while Part III. presents the prac- 

 tical applications of furnace gases, illuminating gas, the sulphuric 

 acid industry, the atmosphere, elementary analysis, and the heat- 

 ing power of fuel. The reputation of the author is guarantee for 

 the value of this nevv volume to chemists interested in his lines 

 of work. 



AMONG THE PUBLISHERS. 



A NEW eJitio.i of the " N^w Elenentary Algebra," by Charles 

 Davies, LL. U , edited by Profes.^or Van Amringe of Columbia 

 College, has been issued by the American Book Co. This 

 work, it seems unnecessary to say, so well known is it, is designed 

 to supply a connecting-link between arithmetic and algebra, to 

 indicate the unity of the methods, and to conduct the pupil from 

 the arithmetical processes to the more abstract methods of analy- 

 sis by simple and easy gradations, and to serve as an introduction 

 to more advanced works on the subject. The present edition has 

 incorporated in it such emendations as the progress of educational 

 science has suggested. 



— The American Book Company have just published the 

 ■'Standard Arithmetic," embracing a complete course for schools 

 and academies, by William J. Milne, Ph.D., LL.D., president of 

 the Nevv York State Normal College at Albany Recognizing 

 the fact that, aside from the general knowledge of arithmetic 



necessary to all intelligent persons, there are special applications 

 of this branch of mathematics that call for special training oa 

 the part of the student, the author has prepared this work with a 

 view to meeting such requirements. Provision is made to fur- 

 nish ample practice, for instance, for the student who desires 

 merely to become a rapid and accurate accountant, as well as for 

 the one who prefers the training which cultivates the reasoning 

 powers at the expense of practical expertness in the use of num- 

 bers. The scope of the work is sufficiently comprehensive to 

 meet the demands of even the moat advanced school. 



— "Nature Study for the Common Schools" is the title of a 

 neat volume of about 450 pages from the press of Henry Holt & 

 Co. It is the work of Wilbur S. Jackman, A. B., teacher of 

 natural science in the Cook County Normal School, Chicago, and 

 is intended to be a guide for teachers in the common schools, who 

 wish their pupils to pursue an adequate and symmetrical course 

 in natural science. The plan adopted is based upon what the 

 author believes to be the proper interpretation of the charactec 

 of the knowledge that the average child may be readily induced 

 to acquire. Instead of endeavoring to give the pupil a thorough 

 knowledge of a few animals and plants, an effort is made to give 

 him some knowledge of everything with which he comes into 

 contact; this knowledge, of course, once acquired to serve both as 

 foundation for and incentive to further acquisitions in the same 

 general direction. The volume, it maybe well to add, is written 

 for the teacher, not for the pupil. 



— At the October meeting of the Agassiz Club at Corvallis, 

 Oregon, a society recently formed for the discussion of scientifie 

 subjects, Professor H. T. French exhibited some clover growing 

 in a root-cage, and showing nitrot<en nodules on the roots; Pro- 

 fessor Craig, some alfalfa infected with dodder, and Professor 

 Washburn, a nevv insect- breeding cage. Thepaper of the evening 

 was by Mr. Thomas Jeffreys, and was entitled -'What consti- 

 tutes American citizenship ? " 



Dr. T. H. Andrews, Jefferson 

 Medical College, Philadelphia, says of 



Horsford's Acid Phosphate. 



"A wonderful remedy which gave me 

 most gratifying results in the worst 

 forms of dyspepsia." 



It reaches various forms of 

 Dyspepsia that no other medi- 

 cine seems to touch, assisting 

 the weakened stomach, and 

 making the process of diges- 

 tion natural and easy.

RACES AND PEOPLES. 



By DANIEL G. BRIN ION, M.D. 



'The book is good, thoroughly good, and will long 

 nain the best accessible elementary ethnography 

 in our language.'^ — The Christian Union. 



"We strongly recommend Dr. Brinton's 'Races 

 and Peoples' to both beginners and scholars. We 

 are not aware of any other recent work on the 

 science of which it treats in the English language." 

 —■Asiatic Quarterly. 



"His book is an excellent one, and we can heartily 

 recommend it as an introductoiy manual of ethnol- 

 ogy.'"— T/ie Monist. 



"A useful and really interesting work, which de- 

 serves to be widely read and studied both in Europe 

 and America,.''''— Brighton (Eng.) Herald. 



"This volume is most stimulating. It is written 

 with great clearness, so that anybody can under- 

 stand, and while in some ways, perforce, superficial, 

 grasps very well the complete field of humanity. ''■' — 

 The New York Times. 



"Dr. Brinton invests his scientific illustrations and 

 measurements with an indescribable charm of nar- 

 ration, so that 'Races and Peoples,' avowedly a rec- 

 ord of discovered facts, is in reality a strong stim- 

 ulant to the imagination." — Philadelphia Public 

 Ledger. 



" The work is indispensable to the student who re- 

 quires an intelligent guide to a course of ethno- 

 graphic reading." — Philadelphia Times. 



Price, postpaid, $1.75. 



THE AMERICAN RACE. 



By DANIEL G. BRINTON, M.D. 



" The book is one of unusual interest and value." — 

 Inter Ocean. 



" Dr. Daniel G. Brinton writes as the acknowledged 

 authority of the subject.^''— Philadeli^hia Press. 



" The work will be of genuine value to all who 

 wish to know the substance of what has been found 

 out about the indigenous Americans." — Nature. 



"A masterly discussion, and an example of the 

 successful education of the powers of observation." 

 —Philadelphia Ledger.
