an extraordinary Introfufception. 309 
Upon cutting through the coats of this inverted inteftine it 
was obferved, that they were very much thickened and difeafed ; 
the enlargement of the gut, which was fully equal to that of an 
adult, confiding chiefly in a thickening of its various mufcular 
fibres *, The peritoneal coat, now become its internal furface, 
was every where highly inflamed, but not black as on the outfide, 
the inflammation gradually increafing from the band to the extre- 
mity of the caecum. Through the whole length of its cavity was 
included a portion of the ileum uninverted, with its connecting 
mefentery, which communicated with the larger aperture above 
described at the extremity of the caecum, and with the arch of 
the ileum above the band. It was contracted in fize, but was 
nearly free from thickening or inflammation ; fome adhefions 
only connected it with the coats of the colon ; but the portion 
above the band was at leaf!: four times as large, thus refembling 
in magnitude as well as occupying the place of the great arch 
of the colon. Befides this inteftine, this cavity contained a 
portion of the omentum continued from that above, palling 
within the band, and extending half-way to the reCtum; an 
enlarged clufter of mefeuteric glands, of the fize of a pigeon’s 
egg, which juft emerged from under the band, and were connected 
with a portion of the mefentery above ; and, at the lower part, the 
appendix vermiformis larger and longer than natural, but like- 
wife uninverted, the mouth of the cavity of which formed the 
fmaller opening in the cascum before mentioned. It was at 
this point of the diffeCtion that the fame ingenious Surgeon 
drew the figure, tab. VIIL 
* The increafed a&ion of thefe mufcles, neceflarily attendant on their inverted 
ftate, would increafe the fize of their mufcular fibres, as happens in the bladder, 
when it ads frequently.
