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 intefline were two apertures, viz. the large one felt by the finger per anumy 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¬ sion 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 intefline down. Th is 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. Basire very accurately reduced the fcale under my own infpett-ion from whkh the engravings are taken.
