branes, becaufe they were covered with the Particles 
of Fat, with which thele Membranes or Skins had be- 
fore been filled. 
I caufed a few of thefe Skins of the fat Globules 
to be drawn, as may be leen here at Fig. x. between 
E, F, G, H. During the faid Obfervation, I fix’d my 
Eye with attention upon the fat Particles of the Sheep 
which had been melted, and were again coagulated ; 
and I could not but judge, that thefe fat Particles, 
which were exceeding fmall, were analagous to that 
internal Matter, wherewith fbme of the fmallefl little 
Seeds are furnifhed, and in a great many of thefe ex- 
ceeding fmall Particles, I could in clear Weather dif- 
cover fbme Tranfparency. 
Moreover, I cut as thin Slices as it was pofiible 
of the Fat, yea fb thin, that five or fix of them did 
not weigh a Grain, and put them into a little Water, 
in order to try whether I could make any farther Difi 
coveries thereby, with refped: to the fmall Particles 
of Fat ; but it was in vain : only I faw floating upon 
the Water very fmall Particles of Fat, which were co- 
agulated in a Ipherical Figure, and the very biggeft of 
thofe fat Particles was no bigger than a Grain of Sand. 
I placed thefe Particles upon a Glafs Plate ; and view- 
ing them with a Microfeope, I obferved the Figure, 
which I mention’d above, as plain as before ; and other 
fet Particles feemed to be of a different Figure. I put 
one 'of thefe into the hands of my Painter, or Defigner, 
bidding him to draw what he obferved, it being the 
Figure of one of the faid fat Particles, which was co- 
agulated On the Water, as it is reprelented here by 
^ Fig. 3. ‘‘between I, K? L, M, which was not very con- 
formable with die other melted fat Particles ; for in 
the doing it, all the Particles did not melt, for the 
far Particles are not all extrabtedby the Water, and co- 
agulate
