Chemical pathology. Being a discussion of general pathology from the 

 Standpoint of the chemical processes involved. By H. Gideon Wells, prot. 

 of pathology, Univ. of Chicago and Rush Med. Coli., and Director of the Otho 

 S. A. Sprague Memorial Inst., Chicago. 2d ed. Pp. 616 — 4%X7; $3-25 net. 

 W. B. Saunders Co., Phila., 1914. The second edition of this invaluable text 

 book fully meets the expectations of those of us who have constantly used the 

 first edition (issued in 1907). It is impossible to suggest the merits of this 

 splendid volume in notes as brief as these without the use of Superlative terms in 

 every line of comment. Written by one who has been thoroughly trained in 

 pathology and biological chemistry, and whose experience as a teacher and 

 investigator of the chemical aspects of pathology has been exceptional, this 

 volume by Wells presents in masterly manner the essentials of chemical pathology 

 from every standpoint of importance. Practitioners of medicine, expert pathol- 

 ogists, laboratory workers in every medical school and Institute, biological chem- 

 ists everywhere, and biologists in general, will find this book of exceptional 

 Utility. A biochemical laboratory cannot be up to date without it. 



Chimie pathologique tropicale de la region Atiantique. By G. Delgado 



Palacios, prof., Univ. of Caracas, Venezuela. Pp. 318 — 4% X 6^- Published by 

 the author, 1914. A special treatise on feces, intoxications of intestinal origin, 

 nutritional disturbances due to intestinal influences, and intestinal disinfection, 

 especially from the Standpoint of nutrition in the tropics. The author describes 

 the calcareous product from feces of inhabitants of the tropics, called " carcoma 

 fecale," which occurs in the form of granules 0.1-0.3 mm. in diameter, and con- 

 tains unrobilinogen and another chromogen termed cholerythrogene — a name 

 intended to suggest the origin of the new chromogen and the color of its pig- 

 ment derivative. The origin, significance and properties of " carcoma fecale " 

 and cholerythrogene, and their relation to yellow fever and tropical pathology, 

 are discussed in detail. The book concludes with a section on biochemical 

 methods of general value. The author is now in this country and may be 

 addressed " in care of the Biochemical Bulletin." 



The nature of enzyme action. By W. M. Bayliss, prof. of general physiol- 

 ogy, Univ. Coli., London. 3d ed. Pp. 180 — 4^X7/^; $i-5o net. Longmans, 

 Green and Co., London, 1914. (One of the Monographs on hio chemistry.') 

 The most valuable book in English on enzymes. The author has incorporated 

 the gist of the many recent discoveries on reversibility, on combination between 

 enzyme and Substrate, and on anti-enzymes. The chapters on these subjects have 

 been rewritten, for the most part, and the whole book brought up to date.
