ill front of the left kidney to the great curvature of the stomach, and 

 bends over to the right side in front of the epiploon, and descending 

 describes a large spiral curve, then a second, third and fourth, pro- 

 gressively diminishing in extent ; the last and innermost is folded 

 upon itself, and repeats two spiral coils in the opposite direction, 

 the extent of these increasing ; and the gut, quitting the mass of 

 closely connected coils, passes backwards, and bends round the root 

 of the mesentery, adhering to that part and to the pancreas above, 

 then descends in front of the duodenum, much diminished in size, 

 and getting to the back of the lumbar region becomes the rectum, 

 and is continued, tightly bound to the sacrum, behind the genital 

 organs and bladder to the vent. The coils of the colon, which are 

 the first viscera that present themselves, and conceal almost all the 

 others in the abdomen, are attached to one another by bands of meso- 

 colon of about an inch in breadth ; and these were laden with lobes 

 of fat. There were many small, dark-coloured glands at the root of 

 the mesocolon, from which straight blood-vessels radiated in gi-oups 

 of from four to eight or ten. The colon, where it forms the first 

 series of coils, is 10 inches in circumference, and is slightly sacculated 

 on two longitudinal bauds. The sacculi subside with a slight dimi- 

 nution of diameter in the returning coils. 



The length of the ' large intestines' was 1 3 feet 6 inches, or nearly 

 four times the length of the entire animal. 



The mucous membrane of the small intestines is produced in the 

 duodenum into four or five narrow longitudinal folds, which in the 

 jejunum are six or seven in number, and are here or there connected 

 together by oblique folds. Towards the middle of the jejunum these 

 folds disappear, and then reappear at intervals progressively increa- 

 sing ; and in the ilium the mucous lining is even and simply villous. 

 In the partial or interrupted extents of the plicated structure, the 

 rugae are more reticulate in their arrangement. The lining membrane 

 of the colon was smooth and even, but gorged with blood, and varied 

 in many parts from a deep i-inous to an almost black colour. The 

 lining membrane of the rectum was disposed in numerous fine longi- 

 tudinal rugse. The small intestines contained only mucus ; the large 

 intestines a dark fluid matter of the usual fsecal odour, with one or 

 two masses of hard faeces, about the size and shape of a pullet's egg. 



The liver weighed 2 lbs. 4 oz. ; it consisted of three principal lobes, 

 viz. a right, middle and left ; the right is the largest, and is partially 

 subdivided at its free extremity, which is closely connected with the 

 right supra-renal body and the summit of the right kidney. The 

 middle lobe is bifid, a gall-bladder 4 inches long by 1| inch broad 

 being lodged in the cleft ; a small ' lobulus Spigelii' projects near 

 the neck of the gall-bladder. The left lobe of the liver terminates 

 on the left side, about 3 inches from the cardiac end of the stomach. 

 The hepatic duct joins the cystic after a course of an inch ; the 

 • ductus communis' is about the same length, and has a width of 

 3 Unes at its termination, which is at the upper part of the beginning 

 of the duodenum. 



The pancreas is a long flattened band, from an inch to an inch
