of blood containing a few hæmatozoa, taken from the right Jugular Vein of horse No. XXIII
during life.
8th.—The animal appears healthy, the appetite is good. The visible mucous mem-
branes are clear and normal in colour and the evacuations natural. There is a small
swelling at the seat of inoculation, the size of a rupee. Temp. A.M. 37.8°C. The hæmatozoon
is absent from the blood. Temp. P.M. 38.1ºC.
9th.— The swelling at the point of inoculation has somewhat increased in size, and now
presents a raised circular tumor one inch and a half in diameter. Temp. A.M. 38ºC.
The hæmatozoon is still absent from the blood. Temp. P.M. 38.l°C.
10th.—The condition of the animal is unchanged. Temp. A.M. 36.7°C. The hæma-
tozoon is absent from the blood. Temp. P.M. 38.3ºC.
11th.—The swelling and oedema at the seat of inoculation has increased and now
measures 2"x2"xl".
Temp. A.M. 36.4°C. The hæmatozoa are absent from the blood.
Temp. P.M. 38.4°C.
12th.— The condition of the animal remains unchanged. The appetite is good and
the evacuations natural. The swelling and oedema at the seat of inoculation have again
increased and now measures 3" x 3" x 1". Temp. A.M. 36.6°C. The hæmatozoon is still
absent from the blood. Temp. P.M. 38.8ºC.
13th.— The swelling and oedema has increased at the lower limit to the extent of: three

from the blood. Temp. P.M. 38.3 o C.
14th. — The lower half of the œdema, at the seat of inoculation, has been absorbed during
the last twenty-four hours, and the tension of the tumour has become less. Temp. A.M.
36.5ºC. The hæmatozoon has appeared in the blood for the first time this morning and
there are now a few visible. Temp. P.M. 38.8°C.

AUTOPSY.
At 11 A.M. July 16th, 1891.
The body is fairly well nourished, and there is no swelling or oedema of the extremities
or of the under-surface of the abdomen.
Thorax. — There are no pleural adhesions or fluid in the pleural cavities.
The lungs fill up the cavity of the chest, the apices and edges of the organs are the seat
of localized emphysema. There are some ecchymoses dotted over the superior surfaces of
the lungs, at some distance apart, varying in size, the largest being as large as a two-anna
piece, the smallest the size of a split pea.
On section the tissues are of a deep red colour, there is no consolidation, but on pres-
sure of the cut surfaces, a little blood and air escape.
The Pericardium contains just a trace of a clear straw-coloured fluid.
Heart — Weighs 5 lbs. 10 ozs., the organ is large, and presents a quantity of yellow
coloured exudation in the position usually occupied by the fatty tissue. Dotted over the
surface of the muscular tissue, and lying under the visceral pericardium are several ecchy-
moses which do not dip into the muscular tissue on section.
The right auricle and ventricle contain some semi-solid dark clot, bathed in fluid
blood. There are numerous sub-endocardial extravasations, dotted over the walls of the
ventricle, but there are only very few in the auricle. The left auricle and ventricle con-
tain some semi-solid clots and in the latter is a large yellow coloured solid clot, which
runs up into the large vessels. The left auricle presents a healthy appearance. The left
ventricular walls are somewhat hypertrophied and there are numerous small sub-endocardial
extravasations dotted over the whole surface of the cavity. The valves are healthy.
Liver small and is rapidly undergoing decomposition.
Spleen.—Weighs 3 lbs. 2 ozs., is somewhat soft. The capsule is dotted over with dark
red coloured ecchymoses.
Stomach.—Presents on section the peculiar yellow colour, well marked at the junction
of the cuticular and villous portions and which spreads for quite three inches on to the
cuticular portion of the organ.
