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 

 appear, two in each jaw, one on each side, behind the three
