92 . THE VETERINARY SCIENCT^ 
4. The incisors or front teeth, situated in the front part 
of the mouth just inside the lips, are twelve in number, six 
above and six below. 
5. The canine or bridle teeth are often absent in the 
mare. They are four in number, two in the upper and two in 
the lower jaw. one on each side a couple of inches back from 
the front teeth. They are from a quarter to three-quarters 
of an inch above the gum, are round and pointed and of no 
particular use. They resemble the eye teeth of other animals. 
6. The molars or back teeth are twenty-four in number, 
six on each side in the upper and six on each side in the 
lower jaw. With these the food is ground and masticated. 
IV. — WOLF TEETH. 
Wolf teeth are two small, round, pointed, temporary 
teeth which vary in size in different animals, situated one on 
each side in front of the molars or back teeth in the upper 
jaw. They commence to grow soon after birth and if not 
pulled or knocked out usually decay and drop out between 
the ages of five and eight years. These teeth affect the eye, 
causing it to look dull and run water. They should be pulled 
out when first noticed. 
V. — SETS OF TEETH. 
The horse has two sets of teeth. The milk teeth are 
temporary and are those that the colt sheds, while those that 
come in and remain without being shed, are called the 
permanent teeth. The cutting of the teeth of the foal varies, 
but at or within nine days after birth he has four front teeth, 
two in the centre above and two below, and in the back part 
of the mouth twelve molars. At from seven to nine weeks 
four more incisors or front teeth appear, one at each side of 
the two centre teeth in each jaw. At nine months he gets the 
last of his milk or temporary teeth, these being the corner 
teeth, two in the upper side and two in the lower side of the 
jaw. At this time he has his full set of milk or temporary 
teeth, consisting of twelve molars or grinders and twelve 
incisors or front teeth, six above and six below, making 
twenty-four in all. As the colt advances in age he sheds all 
these teeth. He then commences to get his permanent teeth. 
When the age of one year is reached, four permanent molars 
appeir, two in each jaw, one on each side, behind the three
