 by Prof. Jacques Loeb, of the Rockefeller Institute, and his title was

Persons who wish to bring themselves down to date on anj' subject 

 whatsoever will be able to spend many hours with the Brittanica Year- 

 Book for 1913 (The Encyclopedia Brittanica Compan}-, ' New York). 

 The activities of the past three years are most thoroughly recorded 

 not onl}^ in the fields of politics, military operations, sport and the 

 technical industries but in the pure sciences as well. The eight pages 

 devoted to botany are contributed by Prof. J. Bretland Farmer, and 

 they arc well worth reading.
