Its habits are in a great measure unknown ; but itfeeds on earthworms, beetles, and various insects; it is particularly fond oldevouring ants, which in numberless legions often destroy all before them,leaving every thing desolate as if destroyed by fire. Having the power ofadvancing or withdrawing itself without injury, in consequence of its struc-ture, this serpent is peculiarly fitted for penetrating into the subterraneousretreats of ants, worms, and other insects; and is able to dig deeper thanany other serpent, its skin being very hard, and its muscles very amphisbsena is not venomous. ORDER I V.—B A TR A C HI A . Reptiles of this order have a heart with one auricle; body covered with anaked skin; lungs two when mature, but with bronchiae like fishes in theirearly stage. THE FROG ^. i. If we examine this animal internally, we shall find that it has very littlebrain for its size; a very wide swallow; a stomach seemingly small, butcapable of great distention. The heart in the frog, as in all other animalsthat are truly amphibious, has but one ventricle; so that the blood can cir-culate without the assistance of the lungs, while it keeps under water. Thelungs resemble a number of small bladders joined together, like the cells ofa honey-comb; they are connected to the back by muscles, and can be dis-tended or exhausted at the animals pleasure. Neither male nor female haveany of the external instruments of generation; the anus serving for thatpurpose in both. Such are the most striking peculiarities in the anatomyot a frog; and in these it agrees with the toad, the lizard, and the serpent. 1 The characteristics of the genus liana, or frog,
