All which considered, severer heads will be apt enough to conceive the opinion of this Animal, not much unlike that of the Astomi, or men without mouths, in _Pliny_; sutable unto the relation of the Mares in _Spain_, and their subventaneous conceptions, from the Western wind; and in some way more unreasonable then the figment of _Rabican_ the famous horse in _Ariosto_, which being conceived by flame and wind, never tasted grass, or fed on any grosser provender then air; for this way of nutrition was answerable unto the principles of his generation. Which being not airy, but gross and seminal in the _Chameleon_; unto its conservation there is required a solid pasture, and a food congenerous unto the principles of its nature. The grounds of this opinion are many; the first observed by _Theophrastus_, was the inflation or swelling of the body, made in this Animal upon inspiration or drawing in its breath; which people observing, have thought it to feed upon air. But this effect is rather occasioned upon the greatness of its lungs, which in this Animal are very large, and by their backward situation, afford a more observable dilation; and though their lungs be less, the like inflation is also observable in Toads, but especially in Sentortoises. A second is the continual hiation or holding open its mouth, which men observing, conceive the intention thereof to receive the aliment of air; but this is also occasioned by the greatness of its lungs; for repletion whereof not having a sufficient or ready supply by its nostrils; it is enforced to dilate and hold open the jaws. The third is the paucity of blood observed in this Animal, scarce at all to be found but in the eye, and about the heart; which defect being observed, inclined some into thoughts, that the air was a sufficient maintenance for these exanguious parts. But this defect or rather paucity of blood, is also agreeable unto many other Animals, whose solid nutriment we do not controvert; as may be observed in other sorts of Lizards, in Frogs and divers Fishes; and therefore an Horse-leech will not readily fasten upon every fish; and we do not read of much blood that was drawn from Frogs by Mice, in that famous battel of _Homer_.
