8 A.M.—Animal appeared in normal health, at 5 P.M. symptoms of acute diarrhœa developed,
accompanied with discharges of mucus from mouth and nostrils. The evacuations became exceedingly
watery, and contained some blood and mucus. Numerous dumb-bell shaped crystals soluble in Acetic
Acid without effervescence were discovered on microscopical examination of the evacuation.

8. A.M.—The animal is much weaker, restless, and apparently suffering from abdominal pains. The
extremities are cold. The glairy discharge from the nostrils and mouth has increased in quantity,
and the evacuations are more watery. At 2 P.M. the animal was too weak to stand, it lay down first
flat on its side, and on attempting to stand the hind limbs refused to support its weight and it roll
ed over again. The corneæ became glazed and opaque and at 8 P.M. the animal died.
REMARKS.
The chief point of interest in this case is that the length of the latent period after the primary inoculation
with soiled blood derived from the rat occupied only 62 hours; whereas after re-inoculation with soiled
Horse Surra blood the incubative period was prolonged to 48 days. This points to the fact that probably
the blood of the Bull contained some antitoxic product, the effect of the first inoculation, which deterred the
development of the hæmatozoon of Horse Surra until after the product had been eliminated from the
system of the animal.

The animal was inoculated subcutaneously at the root of the neck on the left side with 1 c. c. of blood
containing very numerous hæmatozoa drawn from the jugular vein of Horse LXVII (the latter having
been inoculated from Horse LXII).
