The purpose and scope of this hook is best stated by its author. "(I) To give an accurate account of the development of nephelometry; (2) t o present an impartial discussion of the present status of the theory of nephelometry; (3) to give detailed working directions for using a precision nephelometer; (4) to discus nephelometric research; (5) t o give procedures for the determination of a number of inorganic and organic constituents, and (6) t o give an accurate and fairly complete survey of the literature on nephelometry." It is the reviewer's opinion that Dr. Yoe has accomplished his purpose in excellent fashion. The hook is divided into five parts. Part I deals with the theory, instruments, methods, history, etc., of nephelometry. Part II deals with Inorganic Nephelametry. The chapter headiigs are Ammonia, Arsenic. Calcium, Chlorine, Phosphorus, Sulfur. Part III deals with Organic Nephelometry. Analyses for acetone, amylase, mustard gas, fats and oils, lipase, nucleic acids, ,%oxyhutyric acid, pepsin, proteins, purine bases, and trypsin are included. Part I V is a comprehensive hibliography. Part V comprises useful tables such as analyses of glassware, data on the strengths of common acids and ammonia, solubility of several gases in
water, conversion table of liquid capacity units, atomic weights, and logarithms. Every analysis is fully described and discussed, with especial attention t o errors, etc. The original literature references are furnished with each procedure. The hook is abundantly interleaved with moss-section paper, there being a page or so for every procedure. Thus the data for a given analysis may be plotted where they will be most useful. Of added interest are the photograph of T. W. Richards and facsimile letters written by him t o Dr. Kober. A page of errata in Volume I is also included. Nephelometry is a worthy companion volume to Colorimetry. The reviewer is pleased t o congratulate Dr. Yoe on this very useful and painstaking piece of work. Any teacher of advanced quantitative analysis, or any one engaged in work calling for nephelometric estimation, should certainly have a copy of this hook. MALCOLM M. HARING

The primary purpose of the book is t o present practical information about chemical warfare t o the medical officers in our military service. The book is so written, however, that i t should be of interest and value t o others who are interested in national defense. The first chapter gives a brief history of the development of chemical warfare.
Boons The next four chapters deal with the fundamental principles of physics, chemistry, and meterrology which are particularly related to the use of war gases. A classification of the different chemical warfare agents is followed by five chapten in which the specific physiological effects of rhe different gases are discussed. Among the gases included are the following: chlorine, phosgene, chlorpicrin, mustard, lewisite, chloracetaphenone, brombenzylcyanide, diphenylchlorarsine, diphenylaminechlorarsine. The different methods of protecting individuals and armies against gas are outlined in considerable detail. The general plan of organization of the medical department for field treatment and transportation of gassed cases is given. A chapter is devoted to the presentation and discussion of statistics showing the ultimate results of gas poisoning. Very few typographical errors were noticed. There is need of revision in one paragraph, on page 27, in which i t is stated that although alcohols can be prepared synthetically, in practice methyl alcohol is obtained from the dry distillation of wood. The book fulfils its primary purpose admirably, and because of its simple, straightforward presentation it should be of interest t o others than those in the military service. It points out in a couvincing manner that gas warfare is not more brutal or inhumane than other forms of warfare, and t h a t since i t is more efficient, it will probably survive as an instrument of warfare. The book is not intended t o be a text; it is a reference work, and as such it should be of value to students of chemistry, as well as to those studying medicine or military science. ~

This baok opens with the portrayal of the charm physical science had far John Wesley and his conception and survey of this field. It next reveals Wesley as possessing such scientific spirit, methods, and ideas as would further promote science, were the time thoroughly imbued with his viewpoints on these three basic thinrs. With all of this as a background the author clearly shows the philosophy of Wesley in placing religion and science in the same channel, the source of which is a Supreme Authority, and in which religion and science may flaw together with mutual enrichment. The book is rich in citations and deductions by the author to prove that John Wesley, a religionist whom Lecky says, "worked a n epoch in English history," held that physical science was a factor in the proper kind of a cultural basis for his religious ministry and that he was a promoter of physical science on an experimental basis. Wesley is quoted as saying, "Chemistry is what has given the modernists the great advantage they have over the ancients." Dr. Edwin S. Slosson states in the foreword of this baok under the caption, "An Appreciation," that the author "has done a service t o historic t m t h and personal justice in proving that John Wesley was well abreast of the science of his day and showed greater interest in the study of science in its various branches than k common among the preachers of our time and that he showed greater appreciation of its cultural and religious value than is common among scientists."
