To convince myself how far the assertion might be admitted, that the cameleon can exist upon air, I have placed them in a cage, so constructed, as to exclude any thing else, even the minutest insect; when I have visited my captives, they have opened their mouths and expelled the air towards me so as to be felt and heard. In the first stage of their privation and imprisonment, which has continued for more than a month, I have found them in continual motion around their prison, but afterwards their excursions became more circumscribed, and they have sunk to the bottom, when their powers of distension and contraction became languid and decreased, and were never again capable of performing their accustomed transformation. The one which I brought to England preserved in spirits, after undergoing upwards of two months of famine, when I carried it among the grass, or placed it in the thick foliage of a tree, in little more than a week regained its green colour, and power of expansion; but not contented with my experiment, and determined to ascertain it to the utmost, I redoubled my precautions to exclude every thing but air, and my devoted victim was doomed to another series of trial, and continued to exist upwards of a month, when it fell a sacrifice to my curiosity. The eyes of the cameleon may also be considered a remarkable singularity; they are covered with a thin membrane, which nature has given it to supply the want of eye-lids, and this membrane is sunk in the centre by a lengthened hole, which forms an orifice, bordered by a shining circle. This covering follows all the motions of the eye so perfectly, that they appear to be one and the same; and the aperture, or lengthened hole, is always central to the pupil, the eyes moving in every direction, independant of each other; one eye will be in motion while the other is fixed, one looking behind while the other is looking before, and another directed above while its companion is fixed on the earth, so that its eyes move in every possible direction, independant of each other, without moving the head, which is closely compacted with the shoulders. By these quick evolutions its personal safety is guarded, and it perceives with quickness the insects and flies, which it is always entrapping by its glutinous tongue. Without doubt, this species of lizard possesses peculiarities well worthy the attention of naturalists, who only can define them; what I have said I have observed in my leisure moments, and must be considered as a very imperfect detail of its natural history. SECTION IV. _Of the Interment of the Dead._ The ceremony of burial upon the Windward Coast of Africa is conducted with great singularity, solemnity, and extravagant circumstances of condolence.
