THE COW. 
The Cow is the female of the ox tribe, and her young 
is called a calf. A young Cow, when under two years 
old, is called a heifer. The Cow is as useful to mankind 
as the ox, except in ploughing and drawing ; but to make 
amends, she supplies us with milk, from which butter and 
cheese are made. The Cow gives from six to twenty 
quarts of milk in a day : and the faculty of giving it in 
such abundance, and with so much ease, is a striking 
peculiarity, for this animal differs in this part of its 
organization from most others, having a large udder, and

of; it has likewise four teats, whilst all other animals of 
the same nature have but two ; it also yields the milk 
freely to the hand, whilst all other animals, at least those 
that do not ruminate in the same manner, refuse it, unless 
their young, or some adopted animal, be allowed to 
partake it. The nge of the Cow is known by her horns ; 
at four a ring is formed at their roots, and every succeed-

years before their appearance, and then reckoning the 
number of rings, the creature's age may be exactly

Calves, when quite young, are helpless creatures, from 
the great length and weakness of their legs. Sometimes 
they are killed when young, and their flesh is then called
