was found in the kidneys. A microscopical examination was un- 

 fortunately not made. 



Dog 2, — Male, about 40 lbs. weight. Operated March 8th, 1904. 

 He recovered well from the operation, and in three days was placed on a 

 bread and milk diet which was changed to one of flesh (200 gr.) three 

 days later. For six days the dog took this eagerly, but on the seventh 

 refused it. During this day he was somewhat restless. Next morning 

 he was found lying on his side in an unconscious condition, with the head 

 thrown back and the hind limbs drawn up on the abdomen. The head 

 was constantly moved backward and forward on an average of about 70 

 times per minute, but this rhythm was irregular. Each time the head 

 was drawn back the eyelids closed. On pricking the skin with a needle 

 no reflex movement resulted ; on placing the limbs in an unusual position 

 they were not withdrawn (Pawlow's catalepsy). Conjunctival reflex 

 normal; rectal temperature 39° C. ; respirations 12-14 P^r minute; pulse 

 1 10-120 per minute, and irregular both in force and rhythm. 



In an hour or so the clonic contractions of the head disappeared, and 

 after about three hours the dog seemed to have recovered and took some 

 milk. He was kept on a bread and milk diet for some weeks and 

 gained weight. Flesh was then given him again, but no further 

 symptoms were ever noted. He lived several months. An opening, 

 measuring one centimeter across, was found between the veins, and 

 no collateral circulation. 



Dog J. — Male, about 60 lbs. There was a good recovery from 

 the operation. Nothing unusual in the dog's behaviour was noted 

 even although he took large quantities of flesh. Three weeks after 

 the first operation a second operation was performed, when it was found 

 that a large vein entered the portal above the vena pancreatico- 

 duodenalis. A second ligature was therefore applied to the portal vein 

 quite close to the liver. Three days after this second operation the dog 

 was again placed in his metabolism cage, and the urinary analysis 

 proceeded with (see Table H.). This dog did not show any definite 

 symptoms, and died from pneumonia three weeks after the second 

 operation. He rapidly lost in weight, and was usually feverish, some 

 sepsis having probably been developed. 



Dog 4.. — Operated February 27th, 1905. Food was withheld until 

 March 8th, when a diet of milk, bread and butter was given, and
