OWEN ON RUMINANT QUADRUPEDS. 
domesticated cattle of the Romans, Greeks, and Egyptians, 
bore the nearest affinity to the Brahminy variety of cattle in 
India. As the domestic cattle imported by the Spaniards 
into South America have, in many localities, reverted to a 
wild state, so the speaker believed that the half-wild races of 
white cattle in Chillingham Park, and a few other preserves 
in Britain, were descended from introduced domesticated 
cattle. The size of the dewlap, and an occasional rudiment 
of the hump in these white cattle, as well as the approxima- 
tion to the light grey colour characteristic of the Brahminy 
race, seemed to point to their primitive oriental source. But 
the speaker could not regard the pure white colour as natural 
to a primitive wild stock of oxen. It is now maintained by 
destruction of all piebald calves that are produced by the 
so-preserved half-wild breeds. 
If the blood of any of the aboriginal cattle, contemporary 
with the mammoth and hairy rhinoceros, still flowed in the 
veins of any of our domesticated races, he thought it would 
be that of the Bos longifrons transmitted through the short- 
horned or hornless varieties of the oxen of the mountains of 
Wales and Scotland. 
In conclusion the speaker referred to the subjoined table 
of the classification of recent and extinct hoofed quadrupeds, 
as indicative of the progressive extinction of those forms of 
TJngulata least likely to be of use to man, and of the sub- 
stitution of the ruminant forms, which, from the perfect 
digestion of their food, elaborate from it the most sapid and 
nutritious kinds of flesh.
