without any apparent cause taking to another, that various artifices 

 have to be habitually used. The famous Monarque, for instance, 

 would never consciously look at the dam of Gladiateur, and a 

 trick had to be practised. We can partly see the reason why 

 valuable race-horse stallions, which are in such demand as to be 

 exhausted, should be so particular in their choice. Mr. Blenkiron 

 has never known a mare reject a horse ; but this has occurred 

 in Mr. Wright's stable, so that the mare had to be cheated. 

 Prosper Lucas ■" quotes various statements from French autho- 

 rities, and remarks, " On voit des etalons qui s'eprennent d'une 

 " jument, et negligent toutes les autres." He gives, on the 

 authority of Baelen, similar facts in regard to bulls; and Mr. 

 H. Reeks assures me that a famous short-horn bull belonging to 

 his father " invariably refused to be matched with a black cow." 

 Hoffberg, in describing the domesticated reindeer of Lapland 

 says, " Foeminse majores et fortiores mares prse cseteris admittunt, 

 " ad eos confugiunt, a junioribus agitatse, qui hos in fugam 

 •' conjiciunt."'" A clergyman, who has bred many pigs, asserts 

 that sows often reject one boar and immediately accept another. 

 From these facts there can be no doubt that, with most of our 

 domesticated quadrupeds, strong individual antipathies and pre- 

 ferences are frequently exhibited, and much more commonly by 

 the female than by the male. This being the case, it is impro- 

 bable that the unions of quadrupeds in a state of nature should 

 be left to mere chance. It is much more probable that the 

 females are allured or excited by particular males, who possess 

 certain characters in a higher degree than other males; but 

 what these characters are, we can seldom or never discover with 

 certainty.
