ON THE EDUCATION OF THE HORSE. I9i 



but if the ratio of improvement can be reduced to matlie- 

 matical calculation, it is evident that the offspring from 

 such an union, although it maybe superior to the worst of 

 the two parents, yet it will be inferior to the best, if, as 

 we are taught to believe, it partakes of the qualities of 

 them both. 



Thus the produce from a blood horse and a cart mare, 

 will be a heterogeneous monster, inferior to either of its 

 progenitors ; and the same result will ensue from all crosses 

 which are very remote from each other in their individual 

 properties. It would seem therefore that the best way of 

 improving the breed, would be to select the likeliest indivi- 

 duals of the same blood, and to propagate from them only.
