Bergen, J. Y. and O. W. Caldwell. Practical Botany. (Ginn 

 & Co., Boston. 545 pp. ill. 1911.) 

 Material sufficient for a year's course in elementary botany but 

 arranged to be adjusted to a half year course. Those aspects of the 

 subject are presented which have the largest significance to the 

 public in general as well as of interest and educative value to be- 

 ginning students. The book includes the principles of plants nutri- 

 tion, the relation of plants nutrition to soils and climate and to the 

 food of animals and man; it discusses some of the diseases of plants 

 and animals produced by plants; the propagation of plants, plant 

 breeding, forestry and the main uses of plants and plant products. 

 The illustrations are numerous and for the most part new.

 biology, has suffered from the unrestricted use of anthropomorphic,
