 demonstration of apparatus : GRAHAM LUSK (with A. R. 

 MANDEL.) 



An experiment on a diabetic dog showed that whether fasting 

 or fed on meat alone, or on meat and fat, no more fat was burned 

 than in the same dog when he was normal and fasting. 



11. " A demonstration of a modified Eck fistula, with a note 

 on adrenalin glycemia " : ALFRED N. RICHARDS. 



A method devised by Vosburgh and Richards for establishing 

 communication between the portal vein and the inferior vena cava 

 of the dog was described and demonstrated. In this method two 

 cannulas were employed. They were constructed on the same prin- 

 ciple as the one used by Vosburgh and Richards in collecting 

 blood from the hepatic and portal veins without interfering with 

 the normal circulation in those vessels. After suitable incision 

 through the abdominal wall a cannula of that type, i cm. long, 

 was inserted into the portal vein about 2 cm. below the entrance 

 of the pancreatico-duodenalis. A second cannula of similar de- 

 sign was introduced into the vena cava at a corresponding point. 

 By connecting the cannulas with a rubber tube, communication 

 was established between the two vessels. On ligating the hepatic 

 arteries and the portal vein at the hilum of the liver, circulation 

 through the liver ceased and the gland was extirpated. 



By the successful use of this method Vosburgh and Richards 

 have found that the application of adrenalin to the surface of the 

 pancreas brings about a slight rise in the sugar content of the 

 blood even after extirpation of the liver. Their experiments thus 

 far have covered periods of from two to three hours, no system- 

 atic attempts having yet been made to get the animals to survive 

 the operation.
