The animal kingdom, arranged after its organization : forming a natural history of animals, and an introduction to comparative anatomy . which they retain ever afterwards. The mouth is always armed with teeth; their toes, with very few exceptions, are furnishedwith nails; the skin is covered with scales more or less serrated, or at least with little scalygranules; and they engender with either a single or double male organ, according to the genus. All have a tail more or less lengthened, and in nearly every instance very thick at the base:the greater number have four limbs, though some have only two. Linnaeus arranged them into only two genera, the Dragons and the Lizards ; but the latterrequires to be divided into several, which differ in the number of feet, of intromittent organs,in the form of the tongue, of the tail, and of the scales, so that we are obhged to separatethem even into families. The first of these, or that of the Crocodiles, comprises but one genus,— The Crocodiles (Crocodilus, Brongniart),—Animals of large size, which have the tail flattened at its sides, five toes on the fore-limbs, and four on.
