Placed aside, however, it soon becomes strongly saccharine. Should 

 the operation of division of the cord be performed, and the 

 temperature of the animal be afterwards maintained at about the 

 ordinary height by exposure to external warmth, then the liver is 

 as strongly saccharine upon ordinary examination after death, as if 

 the animal had been taken and simply sacrificed. 



By oiling the coats of rabbits and exposing them to cold, the 

 temperature of the body falls, and precisely the same phenomena 

 are noticed as after division of the cord. 



"With frogs in a vigorous condition, the presence or absence of 

 sugar in the liver submitted to the ordinary process of examination 

 after death, is dependent upon the temperature of the animal at the 

 time of the destruction of life. This fact was independently noticed 

 by myself about the time that it was mentioned by Bernard in a 

 communication to the Parisian Academy of Sciences. Bernard's 

 interpretation of it is connected with the relative activity of the ab- 

 dominal circulation ; but, for myself, I bring it forward as strongly 

 supporting the views that have been advanced, and consider it to be 

 explained by the influence of temperature on the post mortem pro- 

 duction of sugar. 



The material which occasions the presence of sugar in the dead 

 liver, has been called by Bernard "Glucogenic matter," a term 

 which, being only specially applicable after death, it is suggested 

 should be abandoned, and replaced by Hepatine. 



The amount of hepatine in the liver of the dog is much greater 

 under a vegetable than an animal diet. The amount is also increased 

 by mixing sugar with animal food. From the examples given, it is 

 shown likewise that the relative weight of the liver presents a pro- 

 portionate variation, according to the quantity of hepatine present. 

 In eleven dogs taken indiscriminately, that had been restricted to 

 an animal diet, the weight of the liver was one-thirtieth that of the 

 animal. The average per-centage of hepatine yielded by eight livers, 

 also taken indiscriminately after an animal diet, was 6' 97. Five 

 instances have been collected of dogs restricted to a vegetable diet 

 for some days prior to death. The average weight of the liver was 

 one-fifteenth that of the animal. In only three of the examples 

 was the actual amount of hepatine determined, but in the other two 

 it was noticed to be exceedingly large. The average given by the
