6th.—Appetite poor. During the twenty-four hours until this morning the animal had
not passed any faeces. The dung balls show in places a trace of blood. Temp.
A.M. 38.5°C. Hæmatozoa few in the blood. Temp. P.M. 38.4°C.
7th.—The animal appears much brighter this morning and is better. The appetite is
good. No faeces have been passed during the last twenty-four hours. Temp.
A.M. 38.3°C. Haematozoa few in the blood. Temp. P.M. 40.1°C.
8th.—The animal had an attack of colic during the night; but it was relieved by opium.
Has passed no fæces. Appetite poor. Temp. A.M. 38 2°C. No hæmatozoa in
the blood. Temp. P.M. 39.5°C. The buccal membrane is dry. The animal
is therefore to get at once 6 eggs in a quart of linseed gruel; and this is to
be repeated every four hours.
9th.—The animal is salivated this morning. The appetite has quite failed. The throat
is sore as evidenced by frequent deglutition. No fæces have been passed.
The eggs and linseed are to be continued every 4 hours. Temp. A.M. 37.2°C.
Numerous hæmatozoa were found in the blood. Temp. P.M. 39.4°C.
10th.— The animal has passed practically no faeces since 6th instant, and absolutely
none since the 7th. The appetite is poor, but the animal looks brighter.
Temp. A.M. 38.5°C. Hæmatozoa numerous in the blood. Temp. P.M. 37°C.
11th.—Death took place at 12 A.M.
AUTOPSY at 9.30 A.M.—There is some fluid in the peritoneal cavity.
Lungs.—A small quantity of bright-yellow fluid is present in the pleural cavities.
The lungs are large and occupy the whole of the pleural cavities. The upper portion of the
left lung is adherent to the costal pleura anteriorly over a space of about six to eight inches.
Right lung.—Vevy dark in colour. There is nothing particular noticeable, except the
presence of 3 small spots, yellow in colour, which are hard and irregular shaped concretions.
On section, the lung substance is very dark in colour, and contains some blood. On pressure
a quantity of fluid containing air exudes from the cut surfaces.
Left lung is in a similar condition to the right; and there is a large concretion on the
upper and superior surface of the lower lobe.
Heart.— The pericardium contains 16 ounces of a dark brown serous fluid; but the
inner surface of the membrane is free from ecchymoses. The right side of the heart con-
tains black clots with a small quantity of blood-stained serum. The valves are healthy.
The left ventricular walls are hypertrophied and contain a large decolourised clot adherent
to the valves and musculi-papillares. Valves healthy. There are several large extravasa-
tions of blood, varying in size, the largest being 1½"x ¾", lying beneath the endocardium.
These are present to a limited extent around the upper part of the right ventricle, but are
much more marked and the extravasated blood is found to penetrate to a greater depth
in the upper portion of the left ventricle.
Stomach. —Large and distended with semi-digested food. On section, the cuticular
portion is extremely white in colour. The villous portion presents some blackening of the
lining membrane, probably post-mortem, due to the generation of Sulphuretted Hydrogen.
Spleen. —Is normal in size and presents some slight mottling over the surface; on sec-
tion, the tissue is firm and normal in colour. In the hilum within the folds of the gastro-
splenic omentum, there are two large glands, one the size of a fowl's egg, and the other
that of a walnut.
Liver.— Much increased in size, weighing 17½lbs., is chocolate brown in colour.
There are no adhesions to the diaphragm; but Glisson's capsule presents some old signs of
inflammation. On the postero-inferior surface of the right lobe, there are several circumscribed
patches of a pearly-white colour, where the capsule has become somewhat thickened. The
anterior convex surface of the liver presents a marked pathological change. This extensive
surface is dotted over with round circumscribed elevated nodules, some yellow in colour,
others white, singly or aggregated together, and varying in size from a pin's head to a
third of an inch in diameter. Some of these aggregations are raised above the surface to the
extent of a quarter of an inch. Localised scars are present on both surfaces of the liver,
giving a puckered appearance to it. On section, the same circumscribed nodules are noticed
in all parts of the gland tissue. These nodules can be readily enucleated from the tissue of
the organ, leaving behind them a well marked tough pearly membrane of appreciable thick-
ness surrounding the cavity occupied by the tumour. These lumps are made up of a hard
calcareous material forming the external shell, whilst the interior is occupied by an inspisa-
ted putty-like material of a light yellow-ochre colour.
Kidneys.— Are pale. There are no petechiæ observable, and they appear healthy.
Remarks.—This was a strong, healthy horse, and he was inoculated with blood contain-
ing the hæmatozoa, on the 19th December. The hæmatozoa were observed in blood taken
from the seat of inoculation on the 22nd, although they were not seen in the general circu-
lation until the 24th instant, when they were few in number. As the horse was a strong
