Berlin, 1914 (Wilhelm Engelmann). — To reflect properly the 

 advances of any rapidly growing branch of science in the form 

 of a textbook requires an adequate appreciation of the progress 

 initiated and a frequent revision to keep it up to date. The fact 

 that Hober's book has attained sufficient popularity to encourage 

 four editions, each an improvement on its predecessor, since 1902, 

 is of itself evidence that this presentation of the interrelations of 

 physical chemistry and physiology is helpful. During this period 

 the physico-chemical viewpoint has indeed become essential for 

 any broad consideration of biological problems. Each successive 

 edition of Hober has maintained its leadership as an authoritative 

 guide in the new field which it covers. A book which has become 

 an almost indispensable work of reference in every laboratory 

 where biological problems are dealt with requires no further 

 review here. l. b. m. 



5. Infection and Resistance, by Hans Zinsser. Pp. xiii, 

 546. New York, 1914 (The Macmillan Co.).— In this book an 

 American student of the phenomena of infection, i. e. "the reac- 

 tion which takes place betw T een invading micro-organisms and 

 their products, on the one hand, and the cells and fluids of the 

 animal's body on the other," has summarized the current knowl- 

 edge of the subject. The volume gives evidence of familiar 

 laboratory acquaintance with the biological features involved 

 along with an extensive study of the literature of infectious 

 disease. Professor S. W. Young has appended a chapter dealing 

 w T ith colloids and the colloidal reactions lately drawn into account 

 in the interpretation of the reactions of immunochemistry. It is 

 gratifying to find in the volume appreciation everywhere of the 

 contributions of American workers in this field. As may be 

 expected in the case of a comparatively new and rapidly growing 

 subject, Dr. Zinsser's chapters deal with much that is problemat- 

 ical and debated ; but there is no serious difficulty in distin- 

 guishing between fact and fancy in his presentation of such 

 topics as antitoxins, opsonins, agglutination, phagocytosis, com- 

 plement fixation, anaphylaxis, and the numerous others which 

 belong to the young science of immunity. l. b. m.

 and Memoirs have been recently issued by the British Museum: 



Catalogue of the Ungulate Mammals in the British Museum 

 (Natural History). Vol. III. Artiodactyla, Families Bovidse, 

 Subfamilies iEpycerotinse to Tragelaphina? (Pala, Saiga, Gazelles,
