SPECIES AND BREEDS. 145

domesticated Horses present the same kind of 
irregularities, and do not differ from each other 
in the same way as the wild Species differ from 
one another. Or take the Genus Dog: the differ- 
ences between its wild Species do not correspond 
in the least with the differences observed among 
the domesticated ones. Compare the differences

with those that exist between the Bull-Dog and 
Greyhound, for instance, or between the St.

the Cattle, the Dogs, is true also of the Donkey, 
the Goat, the Sheep, the Pig, the Cat, the Rabbit, 
the different kinds of barn-yard fowl, —in short, 
of all those animals that are in domesticity the 
chosen companions of man. 
In fact, all the variability among domesticated 
Species is due to the fostering care, or, in its 
more extravagant freaks, to the fancies of man; 
and it has never been observed in the wild Species, 
where, on the contrary, everything shows the 
closest adherence to the distinct, well-defined,

fantastic shapes in the Golden Carp, therefore
