internal Dent, as I had obierved in the Fat of a fmall 
^laife. 
After that the Fat of the Terch had lain an Hour or 
two upon the Glafs, I viewed it again, and obierved 
that the Particles' were leilened, or become imaller, 
and that the Skin of the fat Particles, which as yet 
was beiet with Ibme fat Particles, was, as it were, 
Ihrunk, or wrinkled, and the Fat that was burfl out, 
lay about the fat Particles, and was fb fluid and trail- 
Iparenr, that we could not difcover any Parts in it. 
From this Oblervation I began to think, whether 
each of thele fat Particles was not provided with an 
Orifice, or Hole, out of which the Fat might be pro- 
truded at all times, as often as the Parts of the Fifli 
flood in need of Nourifliment, without an entire lay- 
ing open the Skin of the fat Globules ; for we con-- 
flantly find, that when the Eggs of the Perch, which 
we call the Roe, increafe in Bignefs, its Fat decreales ; 
yea in luch a manner, that when the laid Eggs, or Roe, 
are arrived at their utmofl Bignels, there is leldom or 
never any Fat to be leen upon the Inteftines of the 
Fifli. 
Thus far my Notes go about Fat ; and if my Health 
will allow me, I lhall Ihortly tranfmit to you Ibme 
more of the Obfervations which 1 have fet down in 
writing.
