A second demonstration inserted between anatomy and [the treatise on] the living being.
You will represent here for a comparison, the legs of a frog, which have a great resemblance to the legs of man, both in the bones and in the muscles. Then, in continuation, the hind legs of the hare, which are very muscular, with strong active muscles, because they are not encumbered with fat.

Here I make a note to demonstrate the difference there is between man and the horse and in the same way with other animals.
