Remarks.—This
animal (Bull) was brought to the Laboratory on the 5th March 1891 and
was kept under observation until the 24th of the same month, during which time it appeared
quite healthy and normal in every respect. On the latter date, it was inoculated subcutane-
ously in the right thigh with 1.75 c.c. of blood (containing numerous Surra hæmatozoa)
drawn from the Left Jugular Vein of Horse No. XIX, previously inoculated with the
same disease. On the evening of the 28th March, the temperature rose to 39.7°C. and on
the following morning, one hæmatozoon was discovered on microscopical examination, after
searching through several specimens of blood. On the 30th, no hæmatozoa were found in
the blood, but on the 31st March and April 1st, a few were recognized ; from this date until
the 17th June, no more hæmatozoa or their immature forms were found, although carefully
searched for. On June 17th, 1891, eighty-five days after the inoculation of the Bull, two
Guinea-pigs were inoculated subcutaneously in the right inguinal region with 0.2c.c. of blood
taken from the ear of the animal after carefully washing the part with soap and water and
then with Mercuric Perchloride solution 5 per cent. No. I Guinea-pig developed-hæmatozoa
in the blood on the 27th, ten days after inoculation, whilst No. II Guinea-pig did not develop
any until the 5th July, or 18 days after inoculation. The hæmatozoa were present off and
on in the blood of these Guinea-pigs for a considerable period. No. I Guinea-pig finally
succumbed to the disease on the 8th November 1891, or 144 days after the inoculation:
whilst .No. II died on the 12th October 1891, or 117 days after inoculation.
During the interval which elapsed between the 17th June and 3rd September 1891,
no hæmatozoa were discovered in the blood of the Bull, although several coverglass speci¬
