cxxix
that exuded was found to contain numerous hæmatozoa. Subsequently however several
specimens of blood were taken and carefully examined microscopically; but no hæmatozoa
were recognized. It would thus appear that all the organisms had, on the injection of the
Ol: Terebinthinæ, collected in the superficial capillaries. Temp. P.M. 38.6°C.
17th.—The animal appears dull. There is considerable swelling round the larynx and
the upper part of the trachea. The breathing is accelerated and somewhat difficult. Temp.
A.M. 38.7°0. There are very numerous hæmatozoa in the blood, but many appear to be
more torpid than usual. Temp. P.M. 38.8°C.
18th.—Condition unchanged. There is however no sign of any œdema of the extremities.
Temp. A.M. 38.7°C. Hæmatozoa are very numerous in the blood. Temp. P.M. 38.7°C.
19th.—The animal appears very dull this morning; but the appetite continues to be good.
Temp. A.M. 38.6°C, The hæmatozoa are very numerous, large and active. Temp. P.M.
38.5°C.
20th.—The condition of the animal is about the same as yesterday. The appetite is good.
Temp. A.M 39.3°C. Hæmatozoa are numerous in the blood. Temp. P.M. 39.6°C.
21st.—There is slight œdema of the limbs, and the sheath is also swollen. Temp. A.M.
39.4°C. Hæmatozoa are very numerous in the blood. Temp. P.M. 39.6°C.
22nd.—Condition unchanged. Temp. A.M. 39.3°C. The hæniatozoa are very numerous
and active in the blood. Temp. P.M. 39.5°C.
23rd.—The animal is dull. There are numerous petechias on the conjunctival membranes.
There is swelling and œdema of the abdominal walls and sheath : and that of the extremities
has increased in amount. The appetite remains good, and the evacuations are natural in
character . Temp. A.M. 39.2°C. The hæmatozoa are very numerous and active in the blood.
Temp. P.M. 39.4°C.
24th.—The animal is becoming very weak, and the limbs more swollen and œdematous.
The appetite is however good, in fact very good. Temp. A.M. 38.3°C. The hæmatozoa are
very numerous in the blood. Temp. P.M. 38.5°C.
25th.—This morning the animal looks fairly well. The breathing is somewhat shallow,
25 respirations to the minute. The appetite is however voracious. Temp. A.M. 36.5°C. The
hæmatozoa are numerous in the blood. Temp. P.M. 36.1°C. The animal this evening is
weaker. At 8 P.M. it lay down; and death took place after a very short period of struggling
at 11 P.M.
AUTOPSY at 10 A.M., 26th February 1891.—The body is somewhat emaciated,
the limbs are swollen and œdematous, and there is a similar condition of the most dependent
part of the abdomen and sheath. On removal of the skin of the neck and on opening the
thorax, a considerable amount of yellow coloured material, jelly-like in character, is observed
lying on either side of the trachea and passing down into the chest. There is no fluid in
either of the pleural cavities, nor adhesions of the visceral and parietal pleuræ. The apices
of both lungs are the seat of emphysema. The surfaces of the organs are dotted over with
small irregular shaped extravasations of blood which are found to be lying under the visceral
pleurae, but do not appear on section to dip down into the lung tissue. There are also a few
hard nodules about the size of a pea, which lie at varying depths in the tissue and which
on section are found to be caseous nodules undergoing calcification. These are tolerably easy
to enucleate.
Liver.—Large and dark in colour but presents a few lighter coloured patches on its
convex surface with injected vessels running over their surface. On section, these lighter
portions are found to lie superficially. There are some round white bodies about 20 in
number and varying in size from -1/8 th to 1/4 th of an iuch in diameter dotted over the anterior
and posterior surfaces of the organ, and on section, a few of these bodies are found dotted
through the tissue., and are easily enucleable. The tissues present a dull brown colour, and
one can see injected vessels which occupy the central portion of the lobule running towards the
hepatic vein.
Spleen.— Somewhat enlarged. Weight 3 lbs. 1½ oz. There are a few extravasations on
its surface; and on section, the tissue of the organ is fairly firm and healthy.
Kidneys.—The stellate veins are injected at the lower end of both organs. The capsules
strip easily, and reveal the presence of many small round purple spots, nearly all the size of
a pin's head, lying on the external cortical portion. On section these spots are found to dip
into the cortical portion and pervade its whole structure. An orange coloured material
occupied the lumen of some of the pyramidal tubes.
Stomach.—Healthy.
Bladder.—Normal.
Heart.—Presents numerous extravasations under the visceral pericardium anteriorly
and posteriorly. The walls are much hypertrophied, and the right and left ventricles
contain decolourized clots which run up into the large vessels. All the valves are healthy.
