inconvenience, if not of embarrassment. The necessary data 

 were scattered and, at times, inaccessible. That state of affairs 

 was ended with the appearance of the first edition of this book, 

 which therefore suppHed a want and did it in a way considered 

 eminently satisfactory. 



The second edition contains the same chapters under the same 

 titles, and most of the text is unchanged. Additions have been 

 made, however, to increase the number of pages from 164 to 

 186, these being "new matter suggested by further experience 

 in connection with the instruction in sanitary tactics at the 

 Army War College, and with sanitary units of the troops recently 

 mobilized in Texas." The new matter includes both text and 

 illustrations and is all worthy of place. 



Among the more important changes noted are those made in 

 the model field order on page 21 and in the Chief Surgeon's 

 field order on page 25, both showing improvement, the latter 

 particularly so. The chapter on map reading is amplified and 

 improved. The new matter on pages 60 and 61 is interesting 

 and helpful, as is that at the end of the book dealing with Red 

 Cross organizations and functions. The book is altogether 

 worthy of praise and of even more extended use than it has 

 yet had. 



Paper, print, binding, and size are all satisfactory.

The advance of medical education in the past decade has been 

 such that it would appear as if general compilations of this kind 

 for use of medical students were not of so much importance as 

 previously. The medical student should have, during his 

 undergraduate college career, a thorough course in inorganic 

 and organic general chemistry with the resulting knowledge 

 of analytical methods. Therefore when he has finished his 

 medical college course and secured a knowledge of biochemistry, 

 the books which he should make use of are of a broader cha- 

 racter. 



The present third edition is well printed and an effort has 

 been made to introduce modern facts, yet the basis of these 

 facts is of necessity so briefly sketched that the reader obtains 

 empiric knowledge rather than a general foundation. So, for
