second part deals with the substrates 

 upon which enzymes act. The whole 

 treatise, when completed, promises to be 

 an extremely useful reference work for 

 biologists. 



INVESTIGATIONS ON CHLORO- 

 PHYLL. Methods and Results. 

 By Richard Willstatter and Arthur Stoll. 

 Authorised English Translation from the 

 German by Frank M. Schertz and Albert R. 

 Merz. Frank Schertz

The translators have performed a real 

 public service to American and English 

 biologists in publishing this English 

 translation of the fundamental researches 

 of Willstatter and Stoll on chlorophyll. 

 Since they have published the book at 

 their own expense and risk it is to be 

 hoped that American biologists will 

 indicate their appreciation by buying it 

 for their laboratories and libraries. The 

 translation is very well done.

L'UREE (Recherches de chimie analytique, 

 biologique et agricole). LES FONCTIONS. 

 Dinaphtopyranol, Xanthydrol et Sel de 

 Pyryle (Chimie organique). 

 By Richard Fosse. 



Les Presses Universitaires de France 

 50 francs 6 x 9J; xii + 303 Paris 



This is one of a series of monographs on 

 biologic problems. Fosse is the discov- 

 erer of the xanthydrol reaction for urea. 

 In this volume he summarizes his studies 

 on ureogenesis and the distribution of 

 urea in various animals and plants. As 

 he rarely touches on the work of others, 

 this volume can hardly be compared with 

 the monographs of Werner and Fearom.

Another volume for the benefit of the

 living has it not been overlooked that 

 through countless ages past there is no 

 evidence that man had any more sex prob- 

 lems than a guineapig has? Substantially 

 down until the Puritans saddled the west-
