AgricuUural Bacteriology. By Joseph E. Greaves, M.S., Ph.D., Professor 

 of Agricultural Bacteriology and Physiological Chemistry in Utah 

 Agricultural College. [Pp. xv + 437.] (Philadelphia and New York : 

 Lea and Febiger, 1922.) 



This work deals not only with agricultural bacteriology in the narrow sense, 

 but includes accounts of such related topics as bacteria in air, water bacterio- 

 logy, water and disease, sewage and sewage disposal, bacteria and food- 

 poisoning, preservation of food and bacteria in the arts and industries. The 

 various parts of the subject are dealt with in different degrees of detail, such 

 questions as the bacteriology of milk, water, and sewage being considered 

 simply in outline because books dealing adequately with these questions are 

 already available. The parts of the subject particularly well treated by the 

 author are the general morphology, classification, and physiology of bacteria 

 which form the subject-matter of the first twelve chapters of the book, and 

 bacteria in relation to the soil, a subject which is dealt with in all its aspects 

 and in considerable detail, chiefly in the next fourteen chapters. The rest 

 of the book deals with a number of miscellaneous questions related to agri- 

 cultural bacteriology, including those noted above. 



The book is well written and well produced and forms a notable addition 

 to the literature of bacteriology in relation to agriculture and allied subjects.

Guide to the University Botanic Garden, Cambridge. By Humphrey 

 Gilbert-Carter. [Pp. xvi + 117, with frontispiece, 23 plates, and 

 a plan of the garden.] (Cambridge : at the University Press, 1922. 

 Price 3s. 6(i. net.) 



This excellently printed and original volume belies the usual conception of 

 a guidebook. It is rather a pot-pourri of interesting information respecting 

 a number of selected types arranged on a taxonomic plan. 



No matter where we casually open its pages, the reader will find informa- 

 tion of interest, whether it be the discontinuous distribution of Arbutus, the 

 insectivorous habits of the Pitcher plant, or the drugs obtained from the 

 Elecampane by the pharmacists of the past, and the source of liquorice at the 

 present day. The freshness of treatment in this guide by the Director of the 

 Gardens augurs well for their future development. 



The book is well illustrated, there is an excellent index, and the price is 

 very moderate. It should find a circle of readers even wider than those who 

 visit the gardens themselves. E. J. S. 



ZOOLOGY 



Foundations o£ Biology. By Lorande Loss Woodruff, Professor of 

 Biology in Yale University. [Pp. viii + 476, with 211 illustrations.] 

 (New York : Macmillan Company, 1922.) 

 Within a short space of time we have noted in England the publication of 

 several new books on Junior Zoology — e.g., those of Meek, Graham Kerr, 

 O'Donoghue, and a new edition of Parker by Bhatia. The fever seems to 

 have started in America, and this book by Woodruff contains, as did mainly 

 those above-mentioned English examples, the results of the author's lectures 

 to junior students of Medicine, Forestry, and General Science. 



All these textbooks are much alike, but the American ones do bring in 

 more of the modern work in cell physiology and heredity. Unless, however. 

 Woodruff's book is read in conjunction with some good practical classes it 

 would be unsuitable for classes of medical students. The book seems to us 

 to be more suitable from the purely educational rather than from the point 

 of view of training as a basis for the anatomy, physiology, embryology, and 

 parasitology of later medical studies. Its interest and charm is undoubted,
