Beyond this age the indications of the mouth are based upon the increasing obliquity of the jaws (Fig. 31), giving a more acute angle of incidence of the teeth, the in- creasing changes in the size and shape of all the teeth (Fig. 32), due to their being worn closer to the roots and the narrowing and flat- tening of the lower and upper jaws, respectively, the result of the tissues closing in and crowding the roots of the teeth down so as to keep the worn tables in contact (Figs. 33 and 34). 66. Bishoping is quite commonly practiced on the mouths of second-hand horses that are offered for sale. It consists in burning into the table of the tooth a cup to re- place the one which has been worn out with age. Mouths are usually bishoped to resemble the appearance of the cups at 6 or 7 years of age. The made-over mouth can be detected by the fact that the appearance of the cups is not in accord with the angle or shape of the teeth. Un- less skillfully done the burned cup itself can be recognized, and there will not be the ring of enamel which surrounds the cup of the normal Fig. 34. — Crosa section of an incisor tooth, showing how the shape changes with advanc- ing Digitized by Microsoft®.
