SEXUAL SELECTION: MAMMALS. 
Pab'I' 
It 
a great breeder of clogs, informs me that he has lnioWJJ 
some instances ; he cites the case of one of his ofl'P 
deer-hounds, who would not take any notice of a pa T ' 
ticular female mastiff, so that another deer-hound had 
to be emjjloyed. It would be superfluous to give other 
cases, and I will only add that Mr. Bari', who lias car*-'” 
fully bred many blood-hounds, states that in almo st 
every instance particular individuals of the opposh e 
sex shew a decided preference for each other, hi nail.' 
Mr. Cupples, after attending to this subject for another 
year, has recently written to me, “ I have had full con' 
“ firmation of my former statement, that dogs in breed' 
‘ring form decided preferences for each other, bein? 
“ often influenced by size, bright colour, and individu* 1 ' 
“ character, as well as by the degree of their previo uS 
“ familiarity.” 
In regard to horses, Mr. Blenkiron, the greatest 
breeder of race-horses in the world, informs me th» * 
stallions are so frequently capricious in their choice 
rejecting one mare and. without any apparent ca« s ® 
taking to another, that various artifices have to b 0 
habitually used. The famous Monarque, for instant 
would never consciously look at the dam of Gladiateu 1 '- 
and a trick bad to be practised. We can partly see td 1 1 
reason why valuable race-horse stallions, which are 1° 
such demand, should be so particular in their choice* 
Mr. Blenkiron has never known a mare to reject 
horse; but this has occurred in Mr. Wright’s stably 
so that the mare had to be cheated. Prosper Lucas 4 
quotes various statements from French authorities, and 
remarks, “ On voit des etalons qui seprennent d’u 110 
“jument, et negligent toutes les autres.” He gives, 0,1 
the authority of Baelen, similar facts in regard to bull®*
