SEPTICAEMIA IN RABBITS. 373 



quently, can only present such facts as have been 

 developed by experiments made with a different 

 object. 



Two rabbits injected with full doses of my 

 saliva, in New Orleans, proved to be insuscep- 

 tible to its lethal effects. These rabbits had 

 previously received the following experimental 

 inoculations : 



Rabbit No. 1. Received October 7, 1.35 c. c. of 

 swamp-culture (organisms from swamp mud cultivated 

 in gelatine solution a la Klebs and Tommasi-Crudeli) ; 

 October 28, 1.3 c. c. of spleen-culture (from a rabbit 

 which died from an injection of 0.75 c. c. of swamp- 

 culture in gelatine solution). 



Babbit No. 2. Received October 7, 1.35 c. c. of 

 spleen-culture ; and October 27, 1.26 c. c. of spleen- 

 culture, which injection was repeated the following 

 day. 



On the 12th of November these rabbits both received 

 subcutaneously 1.26 c. c. of my saliva, and. except for a 

 slight febrile reaction, experienced no ill effect from the 

 dose. 



Baltimore, May 24, 1881, injected into a large rabbit 

 1.25 c. c. of virus, not disinfected, from a rabbit recently 

 dead. Result negative. This rabbit had previously 

 (May 13) received an injection of 0.5 c. c. of virus 

 mixed half an hour previously with sodium hyposul- 

 phite in the proportion of one per cent. The virus 

 used in these experiments was bloody serum from a 

 rabbit just dead, which was proved by other experi- 

 ments to be fatal to unprotected rabbits in the smallest 

 quantity. Thus, the needle of a hypodermic syringe 

 (Exp. of June 2, 1881) was dipped into the blood of
