thefe threds conftituting each fcale, which run as through 
t\\Q Center^, are on the other fide, the iQiorteft, and ap- 
pear like unto F or G. likewife F andG, on the other 
fide run through th@ center, I have alfo caufed the fore- 
going Figure to be drawn fide- wilejthe better to reprefent 
the thred-like appearance of each fcale, I fuppofe then, 
that the threds , which in fig* 4. are reprefented between 
EandF, are the fame with thofe in Fig* reprefented 
by 10. fo that the ^/;r^^j-, which come from the point I 
("the fame with E in the former figure.) end here, in N 
andLs where they are the fhorteft j and thofe which eX" 
tend to O, through, orclofe to the r^/2^^r M, where they 
are the longeft, end there, or bend again on the other 
fide, as the (aine do here. In fliort thofe which here ap- 
proach the center 1, are pa the other fide furtheft from 
the center. 
In the aforementioned Obfervations, I have for the 
moft part, endeavoured alfo to difcover the nature of the 
Fitreous humour oitho. Eye ; and which furroundeth for 
the mqft part the ta\d Criftallin humor, for that Icon- 
eluded, it was no watry matter, but rather a tranlparent 
Mufcle 5 But notwithftanding all the means I thereto ul- 
ed, I could not make the leaft difcovery thereof, for that 
this matter always changed into a watery fubftance. 
I further examined the Crijiallin body df the Eyes of 
Fijhes^ which are perfect Globes j and found them alfo 
conftituted of like thin fcales, lying one upon the other, 
as in thofe other Animals before noted : and each fcale 
alfo corapofed oi threds, but thefe threds run not in the 
fame manntr, as thofe of other Animals ; yet, notwith- 
ftanding all the induftry by me ufed, I could not difcover 
the true courfe of them, for when the threds approach 
t\iz center, they appear fo thin, and fo clofe joyned toge- 
ther, that the fight cannot trace them, and caufe fuch a 
confufion, that I cannot be certain, whether they end in 
the center, or return again from thence. By jR^.
