Note mm — BOOK IV.

It is remarkable in the Teeth of Fishes, that in some they are sharp, as also jointed, so as to fall back, the better to catch and hold their Prey, and to facilitate its Passage into the Stomach: So in others they are broad and flat, made to break the Shells of Snails and Shell-Fish devoured by them. These Teeth, or Breakers, are placed, in some, in the Mouth; in some, in the Throat; and in Lobsters, &c. in the Stomach it self; in the bottom of whose Stomachs are three of those Grinders, with peculiar Muscles to move them.
