    / - OBSERVATIONS, &c: « nr X HE natural Frog of the Horfe is placed in the centre of the foie, externally convex, and of a wedge-like form, pointed towards the toe, but expanded as it advances to the heels. In the centre of the broad part there is a fiffure, or feparation. The frog is con- nected internally, with another frog, of a fimilar figure, but different in ftruCture. The external frog is compofed of foft elaftic horn, and totally infenfible. The internal frog has fenfation and is much more elaftic than the horny frog; and at the extremity of the heels is connected with two elaftic fub- ftances called cartilages. The toe of the fenfible frog is united to the coffin bone ; but more than tiine tenths of both frogs are behind the coffin b bone.
