The following experiments give additional weight to the previously 

 described results. 



In the one case the anthrax grew with very great rapidity in the 

 culture fluid, and the clear filtrate contained but a very small quantity 

 of proteid matter. Forty cubic centimetres of this fluid was injected 

 into a rabbit, and the rabbit immediately inoculated in the ear with 

 virulent anthrax blood ; in two days there was very marked oedema 

 at the seat of inoculation, which increased to an enormous extent 

 during the next few days, and then gradually subsided. The rabbit 

 is now perfectly well, twenty-four days after the inoculation. 



In the second case the growth of anthrax had been very slight ; 

 20 c.c. of the filtered fluid was injected, and the animal immediately 

 inoculated in the leg with virulent anthrax blood. In three days 

 there was marked oedema at the seat of inoculation. This spread up 

 the leg to the back, so that there was enormous oedema occupying 

 nearly the whole posterior part of the animal ; this persisted for ten 

 days, and then gradually subsided. The animal is quite well, twenty- 

 eight days after inoculation. 



These cases are of interest, since they are obviously instances of 

 partial protection. The animals are stjll affected by anthrax, but it 

 is only as a severe local affection, and does not kill them.
