VARIETIES OP MANKIND. 449 



species distinct, from the Asiatic, because the invariable difference 

 of their molar teeth is of a description which naturalists have 

 never found accidental. Now there exist among mankind no 

 differences greater than what happen occasionally in separate 

 species of brutes. 



The colours of the animals around us, horses, cows, dogs, 

 cats, rabbits, fowls, are extremely various, black, white, brown, 

 grey, variegated. 



The hair of the wild Siberian sheep is close in summer, but 

 rough and curled in winter ; * sheep in Thibet are covered with 

 the finest wool, in Ethiopia with coarse stiff hair ; f the bristles 

 of the hog in Normandy are too soft for the manufacture of 

 brushes ; % goats, rabbits, and cats of Angouri, in Anatolia, 

 have very long hair, as white as snow and soft as silk. 



The head of the domestic pig differs as much from that of the 

 wild animal, as the Negro from the European in this respect j || 

 so the head of the Neapolitan horse, denominated ram's head cTn 

 account of its shape, from that of the Hungarian animal, re- 

 markable for its shortness and the extent of its lower jaw ;** the 

 cranium of fowls at Padua is dilated like a shell and perforated 

 by an immense number of small holes ; f f cattle and sheep in 

 some parts of our own country have horns, in others not -, in 

 Sicily sheep have enormous horns ; | $ and in some instances this 

 animal has so many, as to have accjuired the epithet polyceratous. 



The form of other parts is no less various. In Normandy, 

 pigs have hind-legs much longer than the fore ; at the Cape of 

 Good Hope, cows have much shorter legs than in England ; |||| 

 the difference between the Arabian, Syrian, and German, horses
