RABBITS
SUBCUTANEOUSLY INJECTED WITH FILTERED BLOOD SERUM.
10th December 1890.—Fresh blood containing numerous Surra hæmatozoa was drawn
from Horse No. III immediately after death, into sterilized glass vessels and set aside for
several hours in order to allow the serum to separate. The serum was then forced through
one of M. Pasteur's porcelain filters.
Three rabbits A, B and C were subcutaneously inoculated during a period of three days'
with varying quantities of serum. A received in all 3 c. c., B 6 c. c. and C 9 c. c.
