The domestic varieties of the Ox have been divided into two races, viz. those which 

 have a hunch on their shoulders, and those which have the back straight. Regarding 

 their derivation from the existing wild races, from theUrus, the Bison, 'or the Yak, all 

 is conjecture. The races with hunches are found in India, the eastern parts of Persia, 

 Arabia, and the African Continent, from the Cape of Good Hope to Madagascar. 

 The great Indian ox of Pennant, or Zebu, equals or surpasses the largest European 

 breeds in size, and the h unch on the shoulders sometimes weighs fifty pounds. A 

 smaller hunched variety has the shape and proportions of an ordinary ox, colour 

 whitish gray, and with the horns bent forwards. A third variety, scarcely larger than 

 the hog, possesses the hunch, but has no horns; and a fourth, with two hunches, is 

 found near Surat. Besides these varieties there is a race reared in Abyssinia, in the 

 Galla country, and northern Central Africa, which is generally white, and provided 

 with immense horns. The straight-backed varieties vary much in form, size, and 

 horns, and are spread over alt Europe. In England the breeds of this valuable ani- 

 mal are much improved, both for the purposes of the dairy and the butcher. The 

 white Urus, a wild variety, formerly inhabited the woods of Scotland and the north 

 of England, and a few of the ancient race are still preserved. The ox is found 

 fossil over nearly the whole of Europe.
