jo 8 Dr. I*£TTsom*s Account of 
with the return, anus, uterus, and bladder; alfo a part of the 
arch of the ileum with the omentum, and a portion of the, 
ftomach and duodenum* 
The Drawing * (Tab. VII.) was taken by Mr. Pole, Surgeon, 
of the natural fize, and the fmall inteftines added from a 
Iketch I made before the parts were removed from the body. 
I then made a longitudinal incifion through the coats of the 
figmoid flexure of the colon, from the anus to the band at its- 
upper part. Within the cavity* which was lined with mucus, 
appeared a large inteftine, taking on the form of the figmoid 
flexure, which on examination proved to be the great arch of 
the colon and the caecum inverted ; fo that the villous coat was 
external, and in contact with the villous coat of the figmoid 
flexure, through the whole extent of both ; at the extremity of 
which inverted inteftine were two apertures, vizi, the large one 
felt by the finger per anum , and a fmaller one. 
It now plainly appeared, that the band was formed by the up- 
per part of the figmoid flexure being drawn tight by the inver- 
fion of the part of the colon immediately above it, the further 
progrefs of which was prevented by the peritoneal connexions 
at that place not giving way; which caufed it to appear as a 
band tying the inteftine down. 
This inclofed inteftine was very much difeafed, the upper part 
next the band being highly inflamed, and as it approached the 
caput coli in the reXum gradually terminated in mortification, 
fo that for three inches from its extremity it was perfectly black. 
No adhefion whatever appeared between the coats of thefe 
inteftines, as this inverted colon might be lifted out of the 
figmoid flexure to the band. 
* Mr. B as i re very accurately reduced the fcale under my own infpe&ion from 
which the engravings are taken.
