Friedlander’s diplococcus of fibrinous pneumonia. This, at least, is 
the inference which Pawlowsky draws from the fact that all of the 
eight rabbits suffering with anthrax, which were injected with it, 
recovered. The staphylococcus aurens stands next in efficiency to 
the diplococcus of pneumonia ; as four rabbits, which were treated 
with it by hypodermic injections, recovered. It is somewhat sur- 
prising to learn that non-pathogenic organisms are capable of curing 
local anthrax. This the author declares to be the faet, and places 
the bacillus prodigiosus third in effectiveness. In the case of this 
bacillus a single hypodermic injection was not successful, but a 
second resulted in cure. Of ten rabbits which recovered from 
anthrax after treatment with the bacillus prodigiosus, eight have 
subcutaneous suppuration at the spots into which this bacillus had 
been injected. Finally, the fourth place as a remedial agent against 
the anthrax bacillus is accorded by the author to the streptococcus 
of erysipelas. Of seven rabbits treated with it, only two died. 
Coming now to the treatment of general splenic fever with 
intravenous injections, it was found that proportionately favorable 
results were obtained only when anthrax bacilli were injected 
simultaneously with the diplococci of pneumonia. Of seven rabbits 
treated in this way, two recovered, three died of embolism, and two 
of anthrax. If the injection of anthrax bacilli was followed by that 
of the diplococci, instead of both being given at the same time, the 
results were not as favorable. This is clear from the fact that of five 
rabbits which were so treated not a single one recovered. It is 
important to note, however, that instead of dying as animals unpro- 
tected from anthrax usually do, in from thirty-six to forty hours, 
the rabbits in question survived from seven to fourteen days, showing 
that the injection had enabled the organism to maintain the struggle 
against the disease for a long time. Intravenous injections of 
staphylococcus aurens did not save the animals from anthrax ; while 
injections of streptococcus of erysipelas and the bacillus prodigiosus 
lengthened the struggle of the animal against anthrax to from three 
to five days.
