HARVEY CARR 



University of Chicago 



This work of Donaldson is a compendium of references and 

 statistical data concerning the development of the Albino and 

 the Norway rat. Its contents can best be described by an 

 enumeration of the topics discussed: — Life History, Biology, 

 Heredity, Anatomy, Physiology, Pathology, Classification, 

 Growth of Body Weight, Growth of various Organs, and Growth 

 in terms of Water, Solids, and Chemical Constituents. As a 

 source of reference, this book will be invaluable to all investi- 

 gators who employ the rat as their laboratory material. The 

 author's name is a sufficient guarantee of the accuracy and com- 

 pleteness of this compilation of data.
