    THE ARRANGEMENT, &C. food, as are too hard to be readily divided by the incisores. OF THE BICUSPIDES.^ These teeth^ which constitute the class next in order to the cuspidatus, were formerly termed the small grinders ; but as this is not the only use for which they are naturally destined, Mr. Hunter more correctly denominated them bicuspides, from their being furnished with two distinct prominences, or points. There are two of these teeth on each side. The first is often a little smaller than the second, and has rather a larger root, approaching' somewhat nearer the form of the cuspidatus ; but in other re- spects they are so similar, that a general descrip- tion will be sufficient for both. The bicuspides are thicker than any of the teeth before-mentioned, from the external to the internal surface, but considerably flatter at the sides. The body terminates in two points, one external, the other internal, the former being the larger and more prominent; so that, on looking at that part horizontally, one of the points only is visible, and little difference is observed be- tween this tooth and the cuspidatus. In the lower jaw, the internal point is so small as to constitute merely a slight prominence. The thickest part of the tooth, from side to side, is where these conical prominences unite, and from thence it decreases to the extremity of the root; but in the other direction it continues broad to nearly the end of the root, is still more grooved than the cuspidatus, and often > PI. 2., fig. 1, 2,3, 4, d, d, e, c.
