staggering in his gait, There is effusion of blood into the anterior chambers of both eyes, a
slight mucous discharge is noticed flowing from both nostrils, snuffling respiration, more marked
than in Case No. I, and a moist cough. The appetite is good. Only one hæmatozoon observed

chambers of both the eyes has increased. The horse is weaker than yesterday. Hæmatozoa
present in the blood but not numerous.
November 1st.—Temp. A.M. 39.6° C., pulse- 68, hard ; patient more emaciated. Numerous
petechiæ have appeared on both membranæ nictitantes. Cough still rather troublesome.
Appetite good. Hæmatozoa few.
November 2nd.—Temp. A.M. 39.3° C., pulse again risen to 78 and hard in character. The
animal gets weaker. Hæmatozoa very numerous in the Mood. Two Guinea-pigs and two
rabbits were inoculated from this horse at 12-30 P.M.
November 3rd.—Temp. 38.9° C., pulse 82, hard and irritable, slight ulceration noticed in.
the near-nostril. The appetite is poor. Urine clear and copious.
November 4th.—Temp. 39.7° C., pulse 99, hard and irritable, respirations hurried. The
animal is now almost blind, he persistently stands, although maintaining the upright position
with difficulty. Hæmatozoa swarming in the blood. At 10 A.M. ;—A male goat was inoculated
with the blood from this horse. At 12 P.M. the horse fell, and after struggling for some
time death took place at 12-45 P.M.
AUTOPSY at 1-30 P.M.—Body emaciated, yellow exudation under the skin in the
sternal region. There were about four ounces of an opaque, amber-colored fluid found in
the pericardial sac and one hæmatozoon was discovered on microscopical examination
of the above fluid. There was pneumonic consolidation of the anterior and outer borders of the
right lung, from which on section a frothy and muco-purulent fluid flowed from the cut ends
of the tubes. There were ecchymoses dotted over the visceral pleuræ, varying from a pink to
a purple colour, the apex of the right lung presented the same pneumonic condition. The
spleen is somewhat enlarged and there are a few petechiæ dotted over the surfaces of the
capsule. The liver is the seat of superficial hepatitis ; on section the tissues are dark in colour,
but appear normal. The kidneys are pale and present no ecchymoses on their surfaces, the
stomach is contracted and contains only fluid ingesta, coats thickened, the cuticular portion
presenting a yellow colour, more especially near the line of demarcation between the cuticular
and villous portions. There are some few petechiæ on the villous coat, there is an effusion of
blood into the anterior chambers of both eyes, and on section the clots present a yellowish
colour.
Remarks.—The disease in this animal as in the case of No. I, was considerably advanced
on its arrival at the Laboratory and it survived only six days after admission. The chief points
of interest in this case are :—
(i). The effusion of blood into the anterior chambers of both eyes observed six days
before death.
(ii). Slight ulceration on the septum of the left nostril.
(iii). The yellow exudation found lying in the subcutaneous tissue of the sternal region
the circumscribed patches of pneumonia, the yellow staining of the tissues in the
stomach especially on the cuticular portion, and lastly the presence of the Surra
hæmatozoon in the pericardial fluid observed post-mortem.
