[c] Shells deserve a Place in this Survey, upon the Account of their great Variety; the curious and uncouth Make of some, and the beautiful Colours, and pretty Ornaments of others; but it would be endless to descend to Particulars. Omitting others, I shall therefore only take Notice of the Tortoiseshell, by Reason a great deal of Dexterity appears, even in the Simplicity of that Animal’s Skeleton. For, besides that the Shell is a stout Guard to the Body, and affords a safe Retreat to the Head, Legs and Tail, which it withdraws within the Shell upon any Danger; besides this, I say, the Shell supplieth the Place of all the Bones in the Body, except those of the extreme Parts, the Head and Neck, and the four Legs and Tail. So that at first Sight, it is somewhat surprizing to see a compleat Skeleton consisting of so small a Number of Bones, and they abundantly sufficient for the Creature’s Use.
