COLLECTED STUDIES IN IMMUNITY. 



was developed which acted only on goat blood-cells of a few individuals 

 and which therefore possessed only a few individual special groups 

 in its immune bodies. Against this isolysin, which represented a 

 relatively small portion of the types of immune bodies found in the 

 goat, our anti-immune body also proved entirely ineffective, as is 

 seen in Table IX. 



TABLE VIII. 



In this experiment the method was exactly similar to that of the 

 previous ones. The blood was from goat No. Ill, 1 cc. of a 5% 

 suspension being used.

We see from this that by treating a goat with ox blood- cells, immune 

 bodies have been formed the main portion of which differs from those 

 obtained by immunizing rabbits with ox blood or goat blood. 



A second species of animal in which we have been able to demon- 

 strate a difference in the immune bodies is the goose. The immune 

 bodies obtained by injecting a goose with ox blood-cells are also not in
