In the last branch of this family, viz., 4.4, it is probable that its 

 unsoundness was introduced through the dams, for 4.4112311 was from 

 a mare by 1.33, and the granddam by 38. Other unsound members of 

 this family cannot be traced through their dams to any horse recorded 

 in these tables. 



4.2111 appears as the sire of a number of mares, which, though 

 mated with sound stallions, threw unsound progeny.
