In the faid DifTertations I obferved three di/Hntt 
Draughts of the Figure and form of the laid Gut, and 
taken by the help of a Microfeope ^ and forafmiich as 
thefe Figures did not agree with my Obfervations, I have 
Mken the Liberty to delineate fomc fmall Particles of the 
faid Gut, )aft as they appeared to me thro* feveral Mi- 
crofeopes, hoping that it will not be taken ill of me. 
I then placed a fmall Particle of the faid Gut with the 
Ourfide thereof before a Microfcope> to (hew how the 
Blood lay coagulated upon the extream Membrane of the 
faid Cut which was unfpeakably thin. 
Fig, i. A, B, C, D, E, F, (hews the Blood as it lay 
fpread within a fmall Compafs upon the outmoft Mem- 
brane of the Gut. 
By G, G, G, G, we reprefented the Oblong fort of 
Drops, where the Blood had been protruded in an extra- 
ordinary thieknefs, and vvas coagulated like that Blood 
that lay upon thofe Parts which are deferibed by B, Q 
D, E, and F. 
Now as we fee how this Blood was protruded thro’ the 
VefTels of the Gut, we may very well fuppofe that the 
fame happens in other Parts of the Body. 
After this I feparated the Membranes of the Girt, (b 
Carefully from one another, that I imagined 1 was come 
to the innermoft Membrane 5 but after that I had obfer- 
ved it with greatet Curiohty, I difeovered that that Mem- 
brane which is here deferibed by Fig. 2, H, I, K, L . M, 
N, O, P, Q, which is the Circumference of it as it ap" 
peared to the Painter, was a double Membrane. 
In this fmall Particle, which was drawn thro’ a larger 
Microfeope than that of Fig. i. there were fuch a vafe 
number of fmall Vefiels and Fibres, that it is almoft in- 
conceivable, as it was impoffible for the Painter to de- 
feribe all thofe that he faw of them, efpecially by rea- 
fon of thofe two thin Membranes lying one upon the 
other ^ for how thin a Membrane foever one places be-
