that it was our own little pet that had wandered 
away, and had been lost. This predilection was not 
induced by any sexual instinct, because this dog was 
also a male. This is a remarkable evidence of the 
disposition among animals, when they have become 
divided into races, to form companionship only with 
their own allied breeds, and to propagate with them.

and sometimes in abundance, and exposed to the 
vicissitudes of the seasons, assumes little variety 
which may not easily be traced to the operation* of 
these causes ; the same soil, climate, and subsistence 
continue to produce a similar race.’* Domestication, 
when it has established a peculiar character, main-

preference removes a tendency to new varieties, until 
altered circumstances give rise to other qualities and 
modifications, when a new breed arises, and maintains 
its own uniformity by an adherence to the same pre- 
ferences, and consimilarities. 
Prince’s jealousy and selfishness leads him to eat

his splenetic temper; but if anything be given to the 
other dog first, when he has been waiting or begging
