The family horse : its stabling, care and feedingA practical manual for horse-keepers . are usually examined to ascertain theage. There are six of these. They are covered by a fine whiteenamel enclosing the dentine or bony substance of the tooth. Ineach permanent incisor, when it first appears, is a large cavity orpouch, extending about one-third of the length from the crown. Thiscavity is lined with enamel, and the lower pait is filled with a darkcement. The incisors or cutting teeth, when new, are oval nearthe summit, and nearly triangular towards the roots. The teethof a horse usually wear down at the rate of about one-twelfth of aninch a year. As this wear goes on, the exposed summits of the teethpresent different aspects from year to year. The accompanyingillustrations, after Thomas Brown, show these changes in the incisorsof the lower jaw. At three years old the two front milk teeth havebeen replaced by permanent ones, with the peculiar hollow in thesummit called the *mark. The canine teeth or tushes, aahorsemen call them, are just showing beneath the gum. At four. -SEVEN TEARS. EIGHT TEAKS. years two more permanent teeth have come, the first two havebecome somewhat worn, and the canine teeth are coming throughthe gums. When the horse attains the age of five years, the per-manent incisors are all in place; the two corner teeth showthe mark very distinctly, while it is entirely worn off from the twomiddle incisors and partly off from the next two. At six years theouter edges of the corner teeth are worn down, and the mark isnearly obliterated from the two next ones. At seven years theedges of the corner teeth are still more worn, the mark is nearlygone from the middle of each, and the four front ones are worndown entirely smooth. At eight years the mark has disappearedfrom all the nippers. The dark spot in the center is a long oval, lined with enamel, which comes near the front of the tooth. At tenyears the marks have worn entirely off the upper incisors, the da
