The Zebu {Bos indicus). A number of breeds of these 
cattle exist throughout China, India, and North Africa, 
varying in size from that of a calf to the full adult of our 
ordinary domestic cattle. They differ much in appearance, 
there being breeds without horns, and some almost without 
the characteristic hump on the shoulders, while in others the 
horns are of great size, and some in which the hump weighs 
from forty to fifty pounds. 
The life of the Zebu is held sacred among the Hindoos, 
and it is not uncommon for a particularly fine bull to be con- 
secrated to the worship of Siva, and then turned loose to do 
as he pleases among the natives, whose gardens he destroys 
and whose homes he invades with perfect impunity. 
They are much used as beasts of burden, and are also sad- 
dled and ridden. They can be acclimated in this country 
with a little care and breed readily. The Society now pos- 
sesses a bull and four cows of a small variety, and a magnifi- 
cent bull of the large, lop-eared breed, jet black in color, 
contrary to the rule of his race, which are generally of a 
mouse-gray. 
The Prong-horned Antelope {^Antilocapra americand) is 
remarkable on account of the formation of its horns in a 
manner peculiar to itself alone. The horns of this species 
resemble in appearance those of the hollow-horned ruminants, 
in which the external covering of horny material grows around 
a solid, bony core. These horns are never shed, and are not 
replaced if lost by accident. In this Antelope, however, the 
outside horny part is shed annually, and replaced, as in the 
Deer; but with the important difference, that in the Deer 
the antler is formed directly by a deposit from the blood, 
while in the Antelope in question it is produced by growth 
and hardening of the epidermis or outer layer of the skin. 
The species is now confined to the plains of the temperate 
regions of the West, where they are very common. They 
are easily tamed, but are very delicate, and will not live for 
any length of time under restraint of any character. 
The Domestic Sheep {^Ovis arks'), like the Goat in its 
domesticated forms, is an inhabitant of the whole world. 
In one of these enclosures are several Yemen Sheep, from 
Persia, imported and presented to the Society by George
