252 NA TURE-STUD Y REVIEW [10:6— Sept, 1914 



The Chemistry of Plant and Animal Life, by Harry Snyder, pp. 

 xxii+388; The Macmillan Co., $1.50. 



This is intended as an introductory book in agricultural chemis- 

 try and such a title would be more apt than the one the book 

 possesses, for the purchaser is at first hopeful that he is going to get 

 a clear statement of the latest information regarding the chemical 

 composition of the organic substances. There is no attempt, 

 however, to do more than give the well known reactions and 

 formulas of some of the simpler organic compounds. And then 

 there follows a simple discussion of the organic compounds found 

 in plants, their values as foods, and a couple of chapters on the 

 feeding of animals. The book is clearly written and will serve 

 admirably as a text in elementary agricultural chemistry, espec- 

 ially if the student realizes beforehand that there is a great deal of 

 the chemistry of both animals and plants that is still unknown.
