larPart the Real Bignefs of whlch^ as it af)pearcd lo 
the naked Ey«, is reprefentcd in Fig. 3. by G H. 
Ac firft 1 did not believe that I fhould have attained 
my end, which was fb to Difcover the Texture of the 
Fi^rey, as to be able to expofe the exaft Circutnvolution 
to my own view, by reafonthat the Scaly Particles were 
dry'd together fo hard that they were as clear as Glafs 5 
but when I had differed the Second Criftalin Humor, 
after the manner as you may fee in Fig. 5* GH. I could 
perceive it very eafily. 
The above- mention d little Particle Fig, q. CDEF 
appear'd no bigger to the naked eye than Fig. 4. I K5 in 
which, by the help of my Microfcope, I could difcover 
the exceeding fine Threads, which I call the Fibrous 
Matter, with a part of the Circumvolution which com- 
pofe a Fifth part or Divtfion of the Hemifphere of the 
faid Griftatlin Humor. 
May we not be amazed with the fight of fuch a Con- 
texture, of which the Painter faid it was impoffible for 
him to Trace the exceeding Fine and Regular Fibres 
with the Red-lead Pencil, but hoped to be a little more 
exaft when he fliould come to defcribe the fame with 
his GravingJron on a Copper Plate. 
Thefe Scaly Particles don't lye thicker on each other 
than the Threads or Fibrous Matter are rcprefented in 
the laft mention d Figure ^ let us but imagine then how 
clofely thefe Particles, lying upon, and near each other, 
muft be united 5 for oiherwifc it would be impoffible 
for the Humor Criftdinus to have fuch a Tranfparency, 
as the nature of that Body requires. 
Now, in order to have a clearer Idea of the Courfe 
of the Fibrous Matter in the Criftaline Humor of a 
Whale s Eye, which Fibres, as I have faid before, lye in 
fo many folds upon each other, I took a common Ball 
(for I could not make the Painter comprehend it any 
other way) and divided it into fuch parts as were ana- 
logous^
