If, as has been insisted, the sire and dam had 

 each a set share in contributing to the inheri-

 a business of rule of thumb which it is not. 

 We do not know how these respective shares are

 and this supplies the reason for the selection of 

 high-class parents as the foundation for the 

 further work of development by suitable envi- 

 ronment. In this discussion I have not taken 

 into consideration the transmission of equine 

 speed, as that is an elusive spark, is not trans- 

 mitted as conformation is and has no bearing 

 on the breeding of animals other than the race 

 horse, though subject in all ways to the influ-
