Some Sociological Considerations 



Arising out of Mr. Robertson's Article on the Heredity of 

 Stamina in the Thoroughbred Horse. 



By GEORGE PERCIVAL MUDGE. 



The investigation of the question of stamina in 

 racehorses by means of exact experiment along 

 Mendelian lines must be preceded by an adequate 

 consideration of the facts which are known to men 

 in every- day contact with the more concrete problems 

 of inheritance in horses. The value of these 

 considerations is very much enhanced when the 

 practical men themselves become interested in the 

 theoretical aspect of the problem and in the Mendelian 

 principles of inheritance. All recent enquiry 

 shows that hidden away as it were in the records 

 kept by practical men, or in the common experiences 

 of life, there are undoubted evidences of segregation, 

 both somatic and gametic. But like many other familiar 

 things they have been passed over and ignored 

 because they were familiar and their place in the 

 scheme of Nature was not adequately recognised 

 in the absence of an unifying and embracing theory. 

 For reasons such as these and for others, the article 

 which is published on " The Heredity of Racing 

 Stamina in the Thoroughbred Horse," by Mr. J. B. 

 Robertson, in this number of the Mendel Journal^ 

 and the article on " Inheritance in Coat Colour," by 

 Mr. Robert Bunsow, which was published in the
