to dip into the structures of the right organ. Mesenteric glands considerably
enlarged and very dark in colour. Intestines healthy in appearance.
No. X.—A country-bred mare, aged, the property of a Gádivála, brought
from Bombay fifteen days previously to its admission to the Laboratory Hospital.
Disease advanced. No authentic information as to the date of attack. Fever
of the continued type with remissions. The animal lived two days under
observation. The hæmatozoa were numerous in the blood.
Autopsy.—Body emaciated, absolutely free from subcutaneous oedema.
Lungs, localized areas of emphysema in the right, together with a thickened
condition of the pleurae and a wedge-shaped portion, semi-solid in structure.
A small quantity of fluid in the cavity of the pericardium. Heart.—No sub-peri-
cardial or sub-endocardial extravasations present. Stomach, healthy. Liver,
calcareous bodies present. Spleen, enlarged, sub-capsular petechiæ present.
Kidneys, normal in appearance, as also the other organs. The chief points of
interest in this case were the presence of a horse suffering from naturally contract-
ed Surra on the Deccan plateau, and the discovery of its previous Bombay his-
tory. The rapidity with which the disease advanced, owing to the animal's hav-
ing been worked in a vehicle plying for hire, and lastly the slight pathological
lesions found after death.
No. LVI.—A grey Arab entire, aged; admitted 23rd December 1891 in
Bombay Veterinary College Hospital with a history of fever of one month's
duration. Lived under observation at the Laboratory for four days. Hæmatozoa
swarming in the blood. The fever was of the continued type with remissions,
but the temperature gradually fell and became subnormal in the morning, but
rose 3.5°C at night.
Autopsy.—Body emaciated, membranes yellow. Lungs, the seat of localized
emphysema, extravasations under the pleurae. Heart, extensive sub-pericardial
extravasations, also numerous sub-endocardial extravasations in the left ventri-
cle, chiefly involving the musculi-papillares. Stomach, cuticular portion healthy,
villous portion presented a Spircptera Megastoma tumor. Liver, signs of old
perihepatitis. Spleen enlarged. Kidneys, right capsule adherent in places, con-
gested. Small intestines, few ecchymoses dotted over the mucous membrane,
no ulceration. Large intestines healthy. Bladder healthy.
No. LXV.—Australian Roan mare, aged; admitted 12th June 1892, with
a history of having drunk water from polluted wells between 17 th March and
14th April 1892. The first symptom noted, consisted of a general eruption of
Urticaria on the 23rd of May 1892. Fever.—The animal was under observation
for a period of sixty-eight days, during which time the fever was of the continued
type, with slight daily remissions interrupted on one occasion only, the fifty-fifth
day, by a short intermission. Treatment.—This animal was submitted to a treat-
ment consisting of mixed Cinchona Alkaloids, and Arsenic. The hæmatozoon
which had previously been present in the blood from the twenty-first to the
twenty-eighth day of the disease, disappeared from the blood under treatment
and remained absent until the fifty-sixth day ; the treatment having been
relinquished on the evening of the forty-eighth day in consequence of the condi-
tion of the animal. On the re-appearance of the organism in the blood the
treatment was re-established, and the blood four days later, for the second time,
became free from the hæmatozoon for a period of nine days, between the fifty-
ninth and sixty-eighth day of the disease; on which latter date the mare
succumbed.
Autopsy.—The body was somewhat emaciated, no oedema of the extremities.
Thorax, no fluid in the pleural cavities and no pleuritic adhesions. Lungs, no
sub-pleural extravasations ; both apices were the seat of atelectasis. The tissues
presented a healthy appearance. Pericardial sac contained 60 c.c. of an orange
coloured fluid. Heart fairly healthy ; no sub-endocardial extravasations. Liver,
localized thickening and opacity of Glisson's capsule ; tissue appeared healthy.
Spleen healthy. Kidneys healthy. Stomach presented a patch, pink in colour,
involving the cuticular portion ; no ulceration. Small and large intestines.—The
former was the seat of a few petechiated patches, no ulceration ; the latter
presented a healthy appearance. Brain, increased amount of cerebro-spinal
fluid—75 c.c.
