" We all know books of science which we ought to read with pleasure, but 

 to which we turn with shrinking. Full, perhaps, of new facts and ideas, they are 

 so expressed as to bore consumedly. ' Heredity ' belongs to another category. 

 He who runs may read, even if he be a beginner, and he who reads will probably 

 not cease to run until he has traversed the last page." Nature. 



" This is certainly the best modern book on heredity to recommend to the 

 student and the intelligently curious." Science Progress. 



" May be regarded as the standard work of reference on this subject. As a 

 judicial summary of an exceedingly difficult and controversial subject it is masterly, 

 while in the matter of clearness of exposition it has no rival." Knowledge.
