name of “ quarter-ill 51 —‘'symptomatic anthrax.” The latter being, 
in the meantime, regarded of greater importance, had directed 
to its elucidation the larger share of attention. 
1. As to the claims of the Pasteurian prepared “ vaccine ” to 
serve as a preventive against the attacks of anthrax: Having ob¬ 
tained from the accredited agents in Paris a supply of this mate¬ 
rial, it was first examined microscopically, and tested on small ro¬ 
dents, to prove the existence of organisms and its possession of 
active properties; in both respects it proved true to description. 
On the 13th of October two young bullocks had injected into 
their subcutaneous tissues a dose'of “premier vaccine,” and on 
the 24th each animal was inoculated with the prescribed amount 
of “ deuxieme vaccine.” It is to be remembered that two inoc¬ 
ulations, with an interval of ten days between each, are deemed 
necessary to obtain protection. Neither of these inoculations 
produced appreciable general disturbance. On the 10th of 
December some virulent material obtained from the spleen of an 
ox which had died from an attack of anthrax, after being diluted 
with distilled water, was injected into the subcutaneous tissues of 
one of the oxen “ protected ” with Pasteur’s vaccine, and of an¬ 
other ox which had not been so protected. There was no appre¬ 
ciable general disturbance in either of these animals. 
Thermometric observations, however, showed a very high tem¬ 
perature in the unprotected animal, remaining, with slight varia¬ 
tions, up to near 107° Fahr., till the 16th. That of the protected 
ox became elevated on the day following to 106° Fahr., after 
which it receded almost immediately to normal. A rabbit inoc¬ 
ulated with the same material and at the same time, died of an¬ 
thrax in eighty-five hours after the operation. On January 28th, 
on obtaining virulent material from one of a number of cattle 
which had perished in an outbreak of anthrax at Chelmsford, 
thirty minims of a mixture of this and distilled water was in¬ 
jected into the connective tissues of the remaining ox protected 
with Pasteur’s vaccine. Beyond the fact that the temperature 
rose on the following day to 106° Fahr., and a little swelling ap¬ 
peared at the point of inoculation, there was nothing worthy of 
remark till February 13th, when an abscess formed at the seat of
