But we may lay afide probability, having cer- tain and undoubted evidence of the exiftence of fuch a connection ; opiate applications to the cor- nea having produced a palfy of the retina, and one fpecics of the cataraCt being generally produced by an affeCtion of the outward furface of the eye. By what means this may be brought about is not fo certain ; but it is not unlikely that »^he ciliary procefles may be inftrumental in protlucing the efleCt, as they evidently conneCt the cryftalline hu- mour with the cornea.
