formation being derived from the male parent, 

 the internal organs chiefly from the female, and 

 so on." 



While on this question of speed and breeding, 

 I may draw attention to another point. We often 

 find that a mare has been mated with a thorough- 

 bred horse because she is fast, in order to produce 

 something still faster. She has proved to be good 

 as a hunter, as a hack, or for driving purposes, and 

 has already continuous strains of thoroughbred in her 

 veins, and her dam was perhaps not so big as herself. 

 According to all established principles, the 

 produce from mares answering this description must 

 degenerate in size, as the bulk of the foal must 

 accord with the room through which the foal has tO' 

 pass. 



When the male is much larger than the female,, 

 the offspring is generally of an imperfect form. 

 If the female be proportionately larger than the 

 male, the offspring is of an improved form. 



The improvement depends on this principle, 

 that the power of the female to supply her offspring 

 with nourishment is in proportion to her size, and tO' 

 the power of nourishing herself from the excellence 

 of her constitution. The size of the foetus is generally 

 in proportion to that of the female parent, and, there- 

 fore, when the female parent is disproportionately 

 small, the quantity of nourishment is deficient and 

 her offspring has all the disproportions as a 

 starveling.
