Humerus.—The Humerus of the Tortoise is short and very much curved. This is made so in order that the animal may thrust its extremities out of the shell and reach the ground, which could not be done if the humerus were straight as it is in most of the other vertebrate animals. 216.

Femur.—The Femur is curved in the same animals for the same reason. 217. Phalanges.—Frogs generally have four fingers, with from two to four phalanges in each finger. Tortoises and Lizards generally have five fingers, and from two to five phalanges in each finger. Fig. 111. Skeleton of the Frog. OSTEOLOGY OF FISHES. 218. Bony and Cartilaginous Fishes—The skeletons of Fishes are of two kinds, those made up of bony, and those of cartilaginous matter. (Fig. 112.) The microscopic structure of the scale of a Pike is seen in Fig. 113. Of the former kind 215. Why is the Humerus of the Tortoise curved? 217. How many fingers have Frogs, Lizards, and Tortoises ? 218. What are the two kinds of skeletons in Fishes I Give examples of each.
