68 Hæmorrhagic Septicæmia.
1 Control died in 36 hours.
Bulls 1, 2, 3, 4 were re-tested a month after the vaccine
injection and inoculation of virus and were found immune.
The investigation of this vaccine was not carried any fur-
ther, as the difficulty in obtaining the pleural exudate proved
that it was not a practical method of operation.
IMMUNISATION BY MEANS OF TOXIN.
The toxin was obtained by sterilizing and filtering broth
cultures 48 hours old. The toxin was used fresh.
