AB C D. I reprerent the Crtjtalhn body of the Eye of » 
fo^-yf//?, and although the circular lines reprefenting the 
/^/^r^^j- conftituting each fcale, be only drawn by a pair of 
Compafles, from the re;2^^r A» to the ^^fw^^r C, and there- 
fore lye more diftant one from the other, then in the 
foregoing figures yet are the threds compofing each 
fcale, not thicker, except in the middle, as here B andD 
they are fomewhat thicker j and the nearer they ap* 
proach to A and C, they are the thinner. Fig. 7. is the 
true bignefs of the Criflallin body of the Eye of a Cod- 
fijh. 
1 have alfo examined, thcCriJlallin bodies out of the 
Eyes o[ Birds, only to view how tht threds of the fiales^ 
conftituting alio the Crijiallin body, run ; and after ma- 
ny obfervations, I have difcerned, that the threds confti- 
tuting t\\^ Crijiallin body of a Turhy-coch^ are extended^ 
like thofe in i7/E?i but as the Crijiallin body of a Fij^s^ 
Eye is perfedly Globular ^ thofe of Birds are a flattifti 
round : as /7^. g.pofited with its flattifh fide D towards 
Cornea Tunica. And when from without the CriftaU 
linbody of the Eye of a Tur\y^Coch^ I had with a very fharp 
knife, taken off many oith^fcaly parts, to bring it to a 
fmaller Globe^ it changed its Figure, and became an Oval 5 
as i?)^. 9, where E, is the fame point with 'wifig- 8. the 
i^r^^/ being, where they meet, fo thin andfmall, that at 
laft they are not diftinguilhable. From whence we may 
conclude^ that the threds oi the fcales, which lye nearelt 
the center, ZVQ in the midft thin 5 as in Fig 6\ at Band 
D is ftiewed^ and make thus an Oval figure: and that 
when, the Crijiallin increafeth in magnitude, the 
threds become then in the midft thicker ; and thus con- 
ftitute a flat round ; as I have perceived it, for thQ threds 
in the Crijiallin body of a Turky coc\, in their thickeft part, 
were thicker than thofe in an Oxei Hog, Sheep, (Sc. 
Before lieave this dijcourfeyl cannot but mention, that
