edge of the sac, towards the abdomen; thence the tegumen proceeded backwards 

 and downwards, and then formed, with the ileum, pretty near their usual convo- 

 lutions, about the middle of the tumour, as they should have done in the abdo- 

 men. The caecum had a very small appendix, but was itself very large; as was 

 the colon through its whole length, while contained in the sac; that part of it 

 which returned into the pelvis again, being much smaller, even only of the dimen- 

 sions of the smaller intestines: the length of the colon too seemed more than 

 usual. The caecum began in the lower part of the bag, and thence the colon 

 kept pretty near the course it should have kept, if the bag had been the abdomen, 

 for a great part of its length ; running up from the caecum along the right side 

 of the bag, to near the pubis, and then crossing over towards the left side, be- 

 fore the duodenum, to the left edge of the hernial aperture; at which place,. 

 slipping behind the lower extremity of the stomach, it appeared in the pelvis, 

 crossing over to its left side: thence to follow the course before described. The 

 pancreas lay in a longitudinal direction, along the concave arch of the stomach, 

 through its whole course: and was placed before the bodies of the vertebra. 

 The ductus choledochus, besides its great length from the liver, to within the 

 hernial bag, was of such a width as easily to admit a middle-sized finger, being 

 about 2-1- inches in circumference: in some parts of its course, it was little infe- 

 rior in width to the gall-bladder, in this same subject. The kidneys were rather 

 small, in general sound, except that some few hydatides were here and there 

 fixed on their outer surface, and that 2 or 3 steatomatous tumours, of about the 

 size of a pea, and white, were in the substance of each : but not rising above 

 their surface: they were each in their proper situation; the left lay behind the 

 stomach, and was less, probably from the pressure it was exposed to. The ure- 

 ters and bladder were in their usual situation; the bladder was no way engaged 

 in the hernia, and a catheter was pretty easily introduced, through the concealed 

 penis, into it. The spleen was small, in its natural situation, and sound. The 

 mesenteric glands were numerous, large, hardened, and surrounded with a fat 

 of a deep yellow, as was the pancreas; no omentum appeared; its place seemed 

 supplied by the fat interspersed among the glands and pancreas. The testes were 

 of a natural size, but loose and flabby, and had many varicose veins on their 

 surface: the right, which was so much out of its proper place, was the least, and 

 laxer of the two: the spennatic vessels belonging to it were large, through the 

 great length they ran. The sac and intestines were adherent, almost at every 

 point of their contact; in sofne places so firmly, that they were with great diffi- 

 culty separated, and often not without danger of tearing: the intestines also ad- 

 hered in the same manner to each other; all, by means of a firm cellular mem- 

 brane. The containing bag was very firm, thick, and strong, as before observed. 

 Its aperture, at the right ring from the abdomen, was so wide, as readily to allow
