consisting of six on each side of each jaw, making twenty-four in all. At five years of age he sheds the four remaining temporary incisors or front teeth, which are replaced by four permanent incisors, known as the corner teeth. It is important to become familiar with the time at which the colt sheds his different teeth, for sometimes the caps or shells of the teeth do not fall off when they should. These should be watched, for they greatly interfere with feeding and should be removed with forceps. At five years of age the canine or bridle teeth make their appearance; thus at the age of five years the colt has all his teeth or what is known as a full mouth. The following table shows the various changes taking place in the mouth of the horse from the time of birth up to the age of five years: Hence the horse has-- --Incisors-- Canine --Molars-- Age Temporary Permanent Temporary Permanent At or soon after birth 4 0 0 12 0 9 weeks 8 0 0 12 0 1 year 12 0 0 12 4 2 years 12 0 0 12 8 3 years 8 4 0 4 16 4 years 4 8 0 0 24 5 years 0 12 4 0 24=40 The table given below indicates the various changes which occur in the mouths of ruminants, and more particularly in the mouth of the ox: RUMINANTS --Incisors-- --Molars-- Age Temporary Permanent Age Temporary Permanent At or soon after birth 4 0 12 0 2 weeks 6 0 1 year 12 4 3 weeks 8 0 2 years 8 12 2 years 6 2 3 years 4 16 3 years 4 4 4 years 2 6 4 and 5 years 0 24=32 5 years 0 8 A table giving the number and variety of teeth as they occur in the domestic animals and in man may be serviceable as one of handy reference, and is herewith appended: Incisors Molars Canine Bicuspid Total 4 6 2 4 Man -- -- -- -- = 32 4 6 2 4 6 12 2 0 Horse -- -- -- -- = 40 6 12 2 0 0 12 0 0 Ox -- -- -- -- = 32 8 12 0 0 6 12 2 0 Dog -- -- -- -- = 42 6 14 2 0
