with the character of the laboratory-work, 

 and who have not access to the reserve 

 stores. In the various departments of eth- 

 nology and industrial art, for instance, the 

 wealth of the museum is exceedingly great, 

 but, until cases have been built and labels 

 printed, it is impossible properly to display 

 it." But the museum is expected, as this 

 work advances, to improve rapidly in at- 

 tractiveness to the visitor and general stu- 

 dent, and in convenience to the investigator 

 and special student. Besides the general 

 report and review of the year's work in the 

 scientific departments by the assistant di- 

 rector, the special reports of the curators 

 and acting curators of the twenty sections 

 and departments are given: a bibliography 

 of the museum, a list of accessions for the 

 year, and special papers, having much inter- 

 est, on "Throwing Sticks" and "Basket 

 Work of the North American Aborigines," 

 by Professor Otis T. Mason; "Eskimo 

 Bows," by John Murdock ; " A Spotted Dol- 

 phin" and "The Florida Muskrat," by 

 Frederick W. True ; and " The West Indian 

 Seal," by Frederick W. True and F. A. 

 Lucas. 



Analysis of the Urine, with Special REF- 

 ERENCE TO THE DISEASES OF THE GENITO- 

 URINARY Organs. By Professors Hof- 

 mann and Ultzmann. Translated by T. 

 B. Brune, M. D., and U. H. Curtis, M. D. 

 Second edition. New York : D. Apple- 

 ton & Co. Pp. 310. Price, $2. 



The favor with which this work has 

 been received in medical circles is attested 

 by the fact that it appeared in three lan- 

 guages during the year of its publication. 

 The present issue i3 the second edition of 

 the English translation, and contains some 

 additions by the pen of the translators. 

 While the book does not pretend to be an 

 exhaustive, treatise on the diseases of the 

 genito-urinary organs, it brings all that is 

 essential for the student and the practi- 

 tioner. Some of the subjects treated of in 

 the different chapters into which the text is 

 divided, are : the histology of the uninary 

 organs, the urine, rcagent3 and apparatus 

 for the approximative determination of the 

 urine constituents, general diagnosis, diag- 

 nosis of the diseases of the urinary appa- 

 ratus. 



Great attention and care arc of course 



paid to the different chemical methods of 

 testing and analyzing the urine and its con- 

 stituents, and the directions are so clearly 

 given that by attentive study and observance 

 of these the student can speedily become 

 proficient in the execution of analyses and 

 in the interpretation of the results obtained. 

 Eight colored plates, finely finished, arc 

 added to this volume. These are not given 

 in the German edition, but arc taken from 

 another work, by the same author, on the 

 " Sediments of the Urine." These draw- 

 ings are to serve as aids in the microscopic 

 examination of the urine deposits, for the 

 microscope bears a part fully as important 

 as chemical analysis in investigations of 

 this kind. 



Oils and Varnishes. Edited by James 



Cameron, F. I. C. Philadelphia : P. 



Blakiston, Son & Co. Pp. 376. Price, 



$2.50. 



This book, one in a series of techno- 

 logical hand-books, contains essentially the 

 matter given in Cooley's " Cyclopaedia " and 

 supplemented from the latest publications. 

 It'is intended for all interested in and work- 

 ing with varnishes and oils, and contains a 

 great deal of practical information. After 

 an introductory chapter on the chemistry of 

 oils, the animal, vegetable, and mineral oils 

 are successively considered at length and in 

 detail. Under the head of " Testing Oils " 

 the different physical and chemical tests are 

 given that can be advantageously employed ; 

 the latter tests embrace methods for both 

 qualitative and quantitative determinations. 

 Separate chapters are allotted to " Resins 

 and Varnishes," and " Testing Resins." 

 The appendix furnishes some interesting 

 tables of prices in England of oils, tallows, 

 essential oils, resins, and varnishes, and sta- 

 tistics of the quantities and values of oils 

 there imported for some years past.
