Another interesting difference was noted between the nursing 

 kittens and the maturer animals. In some instances the red dye 

 Sudan III was dissolved in the fat (butter) administered. In the 

 nursing kitten the liver showed a slight pink color and when a 

 portion of the liver was dried and extracted with ether a dis- 

 tinct pink color was shown in the extract. The same treatment 

 applied to the liver of the more mature animal failed to give 

 the pink color in every instance in which it was tried. 



Two possible theories may be suggested to account for the 

 diminution of the chylonucrons in the portal vein of the more 

 mature animals: (1) that a certain proportion of them are 

 eliminated in the intestinal capillaries and excreted into the con- 

 tents of the intestine; (2) that some of them may be converted 

 into a soluble form — through the absorption of bile salts — 

 and can not therefore be observed under the microscope. 



In the nursing kitten it would appear, from the chylomicron 

 count and the Sudan III experiments, that the liver is utilized 

 for the storage of fat, but in the more mature animals this 

 function has apparently been diminished. The storage of fat 

 in the liver of young animals was noted by Koelliker in 1856.

1. The radiation of the individual components of a hemolytic 

 system does not increase the rate of hemolysis of that system. 



2. Radiation of the whole hemolytic system increases the 

 rate of hemolysis of that system. 



3. X-rays influence the rate at which the equilibrium of a 

 reaction is reached. Further studies are in progress to determine 

 the effect of X-rays on the velocity of chemical reactions.
