NOTICES OF BOOKS. 



The Soil : an Introduction to the Scientific Study of the Growth of 

 Crops.— Sir A. D. Hall, K.C.B., F.R.S. (London : John Murray, 1920, 

 ys. 6d. net). The third edition of this well-known standard work, 

 recently published, is arranged on similar lines to the second edition, 

 but the author states that after an interval of eleven years considerable 

 revision has become necessary in a book dealing with a subject growing 

 so' rapidly as the science of the soil. During the period in question the 

 chief addition to knowledge has been the extended light upon the 

 organisms of the soil, and their functions gained through the Rothamsted 

 investigations. The current views upon the structure of clay and many 

 of the reactions of the soil in which the clay takes part have been con- 

 siderabl}^ modified through the development of the conception of colloids 

 which has taken place of late years. In many other instances it has 

 been found necessary either to record some additional knowledge or to 

 modify the point of view. The volume ends with a useful biblio 

 graphy.
