ing the rabbits up to a maximum of glycogen accumulation by 

 feeding carrots, was not accompanied by a retardation of the disap- 

 pearance of glycogen from the liver. In the two rabbits examined 

 the liver was glycogen free. It is safe to conclude, therefore, that 

 alcohol when given in large amounts to healthy rabbits neither 

 causes the formation nor retards the disappearance of glycogen 

 from the liver. 



34 (126). " The viscosity of the blood during fever and after 

 injection of phenylhydrazin " : RUSSELL BURTON-OPITZ. 



The author had previously shown that cold water and hot air 

 baths produce an increased viscosity and warm water baths a de- 

 crease of the viscosity. In this communication the question was 

 considered whether similar changes occur when the temperature of 

 the body is raised by bacterial activity. 



The experiments were performed upon three dogs during ex- 

 perimental peritonitis (Staphyl. pyog. aureus). The determinations 

 were made at times when the temperature ranged from 38.7 to 

 39.5 0 C. and gave figures which were slightly above the average 

 value of the viscosity of dog's blood. Its specific gravity, on the 

 other hand, was invariably lower than normal, indicating thereby 

 that, in spite of the loss in solids incurred during the inflammatory 

 processes, the blood had retained a high viscosity. 



In another series of experiments the viscosity was tested after 

 subcutaneous injection of phenylhydrazin. The specific gravity of 

 the blood was very low in all cases, the viscosity, on the other 

 hand, very great. It may be regarded as proved, therefore, that 

 these two factors need not preserve a direct relationship to one 

 another. As in the previous work, the blood of these animals lost 

 a large part of its solid matter but retained, nevertheless, a high 

 viscosity.
