In addition to what is already stated, we will add an account of every part of the body of an animal, taken limb by limb.

All those which have blood, have a head as well. A small number of animals, and those only among the birds, have tufts of various kinds upon the head. The phcenix[1] has a long row of feathers on it, from the middle of which arises another row; peacocks have a hairy tuft, resembling a bushy shrub; the stymphalis[2] has a sort of pointed crest, and the pheasant, again, small horns. Added to these, there is the lark, a little bird, which, from the appearance of its tuft, was formerly called "galerita," but has since received the Gallic name of " alauda,"[3] a name which it has transferred to one of our legions.[4] We have already made mention, also, of one bird[5] to which Nature has given a crest, which it can fold or unfold at pleasure: the birds of the coot kind[6] have also received from her a crest, which takes its rise at the beak, and runs along the middle of the head; while the pie of Mars, and the Balearic crane, are furnished with pointed tufts. But the most remarkable feature of all, is the crest which we see attached to the heads of our domestic fowls, substantial and indented like a saw; we cannot, in fact, strictly call it flesh, nor can we pronounce it to be cartilage or a callosity, but must admit that it is something of a nature peculiar to itself. As to the crests of dragons, there is no one to be found who ever saw one.
