DIGESTION. 



The weight of the animal remained stationary for about four days. On the sixth day 

 (November 20th), the weight began to diminish. He weighed on that day, before feed- 

 ing, eleven and one-quarter pounds. November 22d, he weighed but little over eleven 

 pounds. November 24th, he weighed ten pounds. He maintained this weight until 

 December 1st, when the weight again began to diminish. On December 6th, the weight 

 was nine pounds. On December 7th, the weight was reduced to eight and a half pounds, 

 and the strength began to fail manifestly. December 10th and llth, he gained a little, 

 on those days weighing nine pounds; but, after that, he progressively diminished in 

 strength and in weight until death occurred, thirty-eight days after the operation. The 

 weight was then seven and a half pounds, showing a total loss of four and a half pounds, 

 or 37|- per cent. 



During the first nine days of the observation, the animal ate well but not ravenously, 

 taking about three-quarters of a pound of beef-heart daily. On the tenth day, the appe- 

 tite increased. He ate on that day, at one time a pound, and at another, half a pound of 

 meat. He ate on an average about a pound and a half of beef-heart daily, until the day 

 before his death. During the last five or six days, he seemed very ravenous and was not 

 allowed to eat all that he would at one time. At this time he was ordinarily fed twice a 

 day. He would not eat fat, even when very hungry. During the last day, when too

From a rough sketch made the fourteenth day after the operation. A small glass A'essel is tied aroitnd the body 

 to collect the bile, and a wire muzzle, the lower part of which is covered with oil-silk, is placed over the mouth to 

 prevent the animal from licking the bile. The dog is considerably emaciated. 



weak to stand, he attempted to eat while lying down. During the last twelve days of 

 the observation, he attempted constantly to eat the fa3ces. During the last days of the 

 experiment, when the dog had become much reduced in weight, he became very cross 

 and snapped at every animal that came near him. There was never any icterus, fetor 

 of the breath, or falling off of the hair. 



A careful examination of the animal was made after death. The gall-bladder was 

 somewhat contracted but not obliterated, and the fistula would admit a large-sized 

 male catheter. Both ends of the divided bile-duct were found impervious, and there was 

 no passage of bile into the intestine. The abdominal organs were normal, with the 

 exception of evidences of slight peritoneal inflammation around the wound and over the 

 convex surface of the liver. There was no fat in the omentum or anywhere in the body, 

 except a very small quantity at the bottom of the orbit. 



The above observation is a type of the instances which are not very numerous in
