Figure 6 shows the omnivorous teeth of theswine, the canines having an extraordinary 2 6 TEETH OF MA N. development, and being used as instrumentsof attack and Fig. 6.—Teeth op the Swine (Omnivorous). The Teeth of Man.—Let us now consider thehuman teeth. Their most striking peculiarityis their perfect articulation: the opposing teethof each jaw meeting uniformly, and leavingno interval in the under jaw, opposite thecanines, as is the case with the their perfect and complete state, there arethirty-two teeth, sixteen in each jaw; viz.,four incisors, two cuspids or canine teeth,four bicuspids, and six molars. The incisorshave a broad, chisel-shaped body, with aslightly serrated, cutting edge. The cuspidsare round and strong, with a long, taperingroot. The bicuspids, or false molars, have arounded body, terminating on its grindingedge in two points, with a rough groove TEETH OF VARIOUS AXIMALS. 27 between them. The molars are placed be-hind all the other teeth. The crown has asquared or cuboid form, with four points onthe masticating surface, separated by channeleddepressions.
