the author of this paper has used as a means of determination these products 

 obtained from the dog, rabbit, and guinea pig. The most important results 

 obtained from these investigations may be summed up as follows : 



1. The bactericidal power of the leucocytes of different species of animals, 

 as the dog, rabbit, and guinea pig, is in itself variable, and also varies in action 

 on certain pathogenic bacteria. 



2. In comparing the bactericidal power of sterile pus, and of pleural exudate 

 from the same animal, the pus is shown to have absolutely higher but relatively 

 less bactericidal power than the pleural exudate, and does not lose its effective- 

 ness for some days. 



3. The isolated living as well as dead leucocytes of the dog, which possess a 

 stronger bactericidal power than the plasma, maintain this property after heating 

 at 60 degrees C, with the separation of a neutral sterile fluid which does not 

 produce a pronounced agglutination. 



4. The vital processes in the animal body aid the bactericidal effectiveness 

 of the leucocytes of animals of other species, shown to be active /// vitfo, after 

 the introduction of the latter into an animal of another species. The foreign 

 leucocytes become disintegrated ; those constituting an integral part of the animal 

 do not diminish in power or vital activity. 



5. During the process which renders the dog immune to typhoid fever, no 

 bactericidal products are deposited in the leucocytes. Their bactericidal power 

 remains unchanged.
