Fig 2. A BCD reprefents the oval particles of the 
Blood- of a Salmon that weighed above thirty 
pound. 
A B reprefents the particles that appeared flat and 
broad, but did not face the eye direftly. 
Thofe about C came ftrait upon the eye, and for 
the moft part had a little clear fort of a light in the 
middle, larger in fome than in others, v/hich the En- 
graver has done his utmoft to imitate, 
Thefe particles are heavier than the (fo caird) rfc. 
fous Liquor, in which they fwim 3 and which toge- 
ther with the particles conftitutes the Blood : Upon 
which account I ordered it fo, that the particles of the 
Blood finking downwards very flowly, gave the En- 
graver the opportunity of feeing thoufands of them 
falling gradually to the bottom. 
Had I gone immediately to work, and defign'd 'em 
my felf according to my own fight, I had made them 
twice as big as they are, from whence we may ga- 
ther the difference between the eye of one man and 
that of another. 
I likewife put upon a magnifying Glafs the Blood 
of a very fmall Butt, which was not mix'd with any 
Liquor, only the particles lay in their own juice, which 
is called the Serum or Whey of the blood. 
Thefe laft mention d particles are reprefented fig. 3. 
between E and F. 
Tho thefe laft particles are defigned fmaller than 
the firft, yet it muft be underftood, that I could not 
obferve any difference in their Bulk 5 and I am firmly 
perfwaded there is no difference in the bulk 
of the blood particles, fo that the red making in the 
blood particles in a Whale, are not to be fuppofed 
greater than thofe in a fmall Fifli.
