192 JMESSES. BEDDAED AND TEEVES ON THE 



loop, so that when the parts were inspected in situ the precise disposition of this root 

 was not evident (PL XXXIV. fig. 1). The csecum had been displaced forwards, as it 

 were, and to some extent bent upon itself. The bending was of such a character that 

 the base of the csecum concealed from view the root of the loop, while to the inferior 

 aspect of the returning limb of the loop the dorsal wall of the caput coli was adherent. 

 Figs. 1 and 2 show the appearance of parts before and after division of these peritoneal 

 adhesions. 



The csecum [c) was about 2 feet in length, and 20 inches in breadth at its base. It 

 presented three longitudinal muscular bands, between which were enormous sacculi. 

 One band commenced at the ileo-csecal junction and ran to the apex ; a second band 

 ran along the inner or left border of the caput, and was in a line with the attachment 

 of the mesocolon at the base of the csecum ; the third band was continued from the 

 superior of the two bands on the outgoing limb of the colic loop. These three bands 

 all met at the apex of the csecum, and the two first named were proper to the caput 

 coli and were not continued beyond its limits. 



Each limb of the colic loop measured 3 feet. Both limbs became greatly narrowed 

 as the bend of the loop {n) was approached. The width of the outgoing limb at its 

 root was 12 inches, and of the incoming segment at the same point 14 inches. 



At the bend the width of the colon was reduced to 5 inches. Both segments of the 

 loop were deeply sacculated as far as the narrower portion, where the gut became 

 perfectly smooth and presented the appearance of a small intestine (PI. XXXIV. 

 figs. 1, 2, n). 



There were two longitudinal muscular bands upon the colic loop, one at the superior 

 and the other at the inferior aspect of the gut. The superior band was continued on 

 to the loop from the csecum, as already mentioned. The inferior band commenced at 

 the root of the loop, about the base of the caecum. Both the bands were continued 

 from the incoming segment of the loop on to the transverse and descending parts of the 

 colon (fig. 2, PL XXXIV.). 



At the points where the wide segments of the loop passed into the narrow segment — 

 at the point, in fact, where the sacculation ceased — the two bands became joined together 

 at an acute angle, and the single band so formed was almost immediately lost upon 

 the smooth bowel at the bend of the loop. Unless some error has crept into the plate 

 that illustrates Professor Owen's account of the colon of R. indicus, it is evident that 

 the colic bands have a different disposition in the two species. 



The adhesion between the base of the csecum — or, more correctly, the root of the 

 outgoing limb of the loop — and that part of the bowel where the loop passed in to 

 the transverse colon was exceedingly intimate. Indeed, it would be more precise to 

 say that a muscular septum divided the lumina of these two portions of the large 

 intestine. 



At the point where the transverse colon and colic loop joined one another the
