    [ *S ] 1 fituation on the retina. Thefe circum* Dances are fo certain, that the feCtators of Kepler aflure us, if there were no paintings of objeCts on the retina, there could be no vifion. The paintings of objeCts are always oppofed to their natural fituation, confe- quentiy uncertain, unlefs, as he obferves, the foul rectifies them, which it does by palFively oppofing their fituation on the retina. I fhall leave every one to make what reflections they pleafe on this matter, and fhall content myfelf with obferving firft, That the judgment of the foul, on the re- prefentation of objeCts on the retina, corre- fponds with, and conforms to the fituations of external reprefentations on the cornea and conjunctive membranes of the eye. If it be neceffary to bring any farther proofs of fo obvious a truth, as the external impref- Dons made on the cornea, being the only one which is conformable to the true fituation of objeCts in nature, the following expert* rnent mult put it beyond a doubt.
