8 GENERAL PRINCIPLES OF 



reluctant to breed from an unsound sire 

 than from an unsound dam, on the expecta- 

 tion that any hereditary infirmity would 

 be more likely to be transmitted by the 

 latter than by the former. On the vexed 

 question of " roaring " being hereditary, I 

 am strongly of such opinion, for whereas I 

 have frequently seen this infirmity inherited 

 from the dam, I am aware of no case in 

 which it has been derived from the sire. 

 There is in my possession at the present 

 time an animal which, so far as an in- 

 dividual case can, strongly supports this 

 theory. The mare in question is by a son 

 of Governess (an Oaks and One Thousand 

 winner, but a rank roarer, which failing she 

 transmitted to her son) out of a very good- 

 winded mare. The offspring was a decided 

 success, winning some sixteen steeplechases, 

 many of them under heavy weights, and 

 throughout her training never showing the 

 slightest tendency to her sire's family failing.
