7th day of the disease when it registered 37.5° C. It again rose to 40.5° C. on the 9th and remained at
that point until the evening of the 10th day, when it fell to 37.4° C. The pyrexia since March 11th
has been characterized by morning remissions and evening exacerbations especially on the 42nd, 49th,
58th, 102nd, 116th, and 125th day of the disease. During the months of May, June and July this animal
became greatly emaciated but by during August commenced to put on flesh and fill out again.
The following Table shows the length of the paroxysms and intermissions registered during the case,
together with variation in numbers of hæmatozoa recorded in the paroxysms and temperature during each
period.:—

Buffalo I, aged 2½ years, was kept under observation for a period of 44 days previous to inocula-
tion (16th November 1897) on the muffle with a trace of blood containing swarms of Surra hæmatozoa
The material was taken from a young cat, which had previously been inoculated from a Surra horse in
the plains. No change was observed at the seat of the small incision, between the edges of which the
soiled blood was placed. The latent period occupied five days. The time which elapsed between the
first appearance of hæmatozoon and death, viz. 120 days, was made up of 12 paroxysms lasting 39, and
11 intermissions lasting 81 days. During the course of the disease the animal lost flesh, and towards
the last became somewhat emaciated, notwithstanding the voracious appetite which was maintained until
two days before death.
The following Table shows the paroxysms and intermissions registered during the case, together
with the variation in numbers of hæmatozoa recorded in the paroxysms and temperatures during each
period:—

Autopsy.—At 1 P.M , 2 hours after death. Body weight 267 lbs. The body is somewhat emaciated,
and on section no subcutaneous adipose tissue is seen. The lymphatic glands in the neck are some-
what increased in size. The pleural cavities are free from fluid and there are no pleuritic adhesions.
The lungs are fully distended with air, the left organ being the seat of hypostatic congestion. On section
the tissues present a healthy appearance. There are 15 cubic centimetres of a clear straw-coloured
fluid in the pericardial sac.
