Art. XIV.—A new Theory of Vision; by Samuen Row ey, 
M.A. 
My purpose in the following communication is to offer a 
theory of vision which I believe has not been heretofore 
advanced, and which I venture also to believe to be the true 
one. But before entering upon its consideration it may be 
Proper briefly to state, with reasons for rejecting them, the the- 
ories hitherto advanced 
s ra direct his optic axes to the former, he will not see the 
= ted images of the latter as one, though their object is situa- 
be i the. plane mentioned, but as two distinct images, the 
_beriments to the same effect might easily be multiplied.
