The jaws form the basis of all this apparatus : their substance is horny ; pi gt 190. their colour a yellowish brown ; and their form, very extraordinary for an organ of this kind, cannot be better described than by comparing them to the shears used in shearing sheep. They differ, however, in the following par- ticulars : instead of playing upon a common spring, the two blades are found to... work upon a joint, and, instead of being flat, they are slightly curved. These two blades are very sharp, and there is nothing that has life that they cannot cut when the animal causes the cutting edges to glide over each other. For this purpose muscles of great strength are provided, the fibres of which are transverse ; and their office is to approximate the two blades, that are again separated by the natural elasticity of the articulation whereby they are united at one extremity. The aliment, once cut by the jaws, is immediately seized by the papillae of the tongue ; which, being sharp and directed backwards, continually drag, by a kind of peristaltic movement, the alimentary materials into the oesophagus.
