Petit# found only half a grain of this fluid within the capsule of the human lens, and could not obtain sufficient for analytical experiment from eighteen eyes ; he also says he found it in one eye and not in the other. On the Membrane of the Aqueous Humour. When we find a fluid contained in such a cavity as that in which the aqueous humour is lodged, the boundaries of which consist of parts so different in function and structure, we must conclude from analogy that this cavity is lined by a membrane capable of secreting and containing this fluid ; at least the knowledge we have as yet acquired of the animal economy justifies us in drawing such a con¬ clusion. The existence of this membrane has, however, rather been admitted from reasoning, than proved by demonstration. It must be ad¬ mitted that a membrane lining the inside of the cornea has been described, and considered as the membrane of the aqueous humour, but this mem¬ brane lining the cornea appears totally different both in structure and function from a membrane capable of performing such an office \ it is in fact Mem. de 1’Acad, Roy. des Sciences, 1730. p. 445.$
