3.Tt is urg'd That according to my Scheme of the fitaatio^ 
of the correfpondent fibres, the Raies of an obje(5i plaa'E 
laterally (fuppofe toward the %^ ) could not fall upoa 
the fellow Fibres in the right Eye ; for if it were piac'c fo 
flantingly toward the left Eye ihtnit^ could not fall upoa 
the internal lateral Fibres of both Eyes in that pofition; 
but upon the internal of one ^ fuppofe the left Eye ^ md ihe 
external lateral of the right , which would caufe a double 
perception. ThisObjedion I forefaw when I hinted ( inp. 
iy6, of theaforeGiid CoileilioD^ ) that Whether the Nerves 
decufatedor not,, it would he no prejudice to my Opinion,, nay pet" 
haps might more fully confirm my opinion where they do. In chat 
paffage I had refpedlalfo I confcfsio the inverfion of the I-* 
mage in the Eye being redified in the Braiai tho that equally 
preffesany other Hypothefis» and the explication of the thing

fituation of therefpedive parts is not diftinguifli'c fo much 
by the means of that end of the ray that terminates in the Eye 
as oft' other end that touches the ObjeU^ from whence tte 
vibration or protrufion comes. 
But to leave this which does not fo particularly con-
