The canines of the Cat are written thus, t'. Following the canines, but sepai-ated from them by a slight inter\al or dwdt'mo, are, iu the u}>pe jaw four, in the lower three teeth, which correspond to our " grinders," or molars and premolars. In the upper jaw the foremost tooth of this set is as small as one of the incisors, and its crowTi is simple, or uearly so. The next two teeth are larger and hare sharp, cutting edges, divided into three points, or cusps. The .second of these two teeth is much the larger, its edge is more blade-like, and the front part of its inner edge sends off a strong blunt pi-ocess, which is supported by a distinct root, so that this tooth has three roots instead of two like its predecessor; it is also of much greater size than any of those iu front, and, biting like a scissor-blade against the corresponding tooth of the lower jaw, is called the sectorial, or carnassial tooth. tooth with a trausvei-selj'-set, almost flat crown. In the lower jaw, the grinding series is represented by only three teeth, all more or less resem- bling the second of the .series iu the upper jaw. Of these the third is the largest, and is called the lower carnassial, biting, as it does, agahist the ui)j)er tooth of that name. In every case the teeth of the lower jaw bite within those of the upper, and, the jaws being so articulated as to allow only of up and down motion, and being incapable of play from side to side, the molars and premolars entirely lose their character of grinders, and become trencliant, cutting uf) the food, in fact, in precisely the same manner as a pair- of scissoi-s. Now comes the question, which of these teeth are premolars, and which molai-s ? This is decided bv fi
