15th.—The animal has developed a cough during the night, but the skin does not feel
hot. The pulse is 60 and the respirations 16. Nothing is to be heard over the chest by
auscultation. Temp. A.M. 39°C. The hæmatozoon is absent from the blood. Temp. 1 P.M.
39.7°C. No urine was collected. Twelve grains of Arsenic were given during the twenty-
four hours. Temp. 5 P.M. 40.3°C. P. 60. R. 16.
16th.—The cough has still further developed and troubles the animal when it holds its
head in the dependent position. The visible mucous membranes appear slightly injected,
as also the conjunctivae, but there are no petechiæ visible. The pulse is frequent; the vessel
feels hard under the finger, but it is easily compressible. The breathing is tranquil, but
the breath smells exceedingly offensive. There is a muco-purulent discharge from the
nostrils, especially the right. The appetite has somewhat fallen off. Temp. A.M. 39.5°C.
P. 64. E. 20. The hæmatozoon is absent from the blood. Temp. 1 P.M. 39.5°C. P. 84.
No urine was collected. Twelve grains of Arsenic were administered during the twenty-four
hours. Temp. 5 P.M. 39.7°C. P. 72. R. 24.
17th.—The animal presents a somewhat dull appearance and the cough continues to be
troublesome; but although the temperature is 39.6°C, the skin does not feel hot. The
visible mucous membranes appear the same as yesterday, but this morning there are two
petechiæ on the membrana nictitans of the left eye and a large one on that of the right.
The pulse is still frequent, 64, but of low tension. The respirations are normal in character
and frequency, 16 per minute. The hæmatozoon is absent from the blood. Temp. 1 P.M.
39.3°C. Urine, none passed. Twelve grains of Arsenic were given during the twenty-four
hours. Temp. 5 P.M. 40.6°C. P. 64. R 16. Although the temperature is considerably ele-
vated this evening, the animal does not appear to be any worse. It has eaten its ration of
corn, bran, &c, as usual. The breathing is tranquil.
18th.—Death occurred at 2 A.M.
AUTOPSY.—Body emaciated. Hind limbs slightly œdernatous.
Thorax.—The right pleural cavity contains sixty ounces of a turbid, yellowish coloured
fluid. The external surface of the right lung is adherent to the costal pleura from the
first to the seventh rib, and between the two surfaces of the membrane a thin layer of
yellow coloured exudation is apparent. There are numerous sub-pleural ecchymoses, dark-
purple in colour, dotted over the posterior surface of the organ.
On section the interior lobule is found to be the seat of well marked emphysema
which also involves the inferior angle and border. The rest of the organ is undergoing
decomposition, but is quite free from consolidation.
The left pleural cavity contains twenty-one ounces of a turbid, yellow coloured fluid.
The external surface of the organ from the first to the seventh rib is adherent to the costal
pleura, and presents the same changes found in the right and the posterior surface or base
is adherent to the corresponding portion of the anterior surface of the diaphragm. The
anterior lobule and the anterior half of the organ, when the exudation is stripped off,
present a dark purplish-red colour, and are hard to the touch. The posterior portion is
dotted over with sub-pleural ecchymoses, circular in form, the largest of which do not
exceed th of an inch in diameter. On section, the anterior half is the seat of consolidation,
but the posterior is fully distended with air.
The 'pericardial sac contains four ounces of a turbid, amber-coloured fluid, but there
are no adhesions or signs of pericarditis, although the exterior wall is considerably
thickened and the vessels injected.
Heart.—The base is the seat of a certain amount of yellow-coloured exudation, which
is freely dotted over with small dark-coloured but circumscribed ecchymoses. The mus-
cular surface of the organ is free from sub-pericardial extravasations, except at the extreme
apex, where a patch presents itself, half an inch square, which is made up of small ones,
aggregated together.
On section, the right side of the heart is found to contain dark-coloured fluid blood,
with a few small dark clots entangled in chordæ tendineæ. The lining membrane of both
cavities is blood-stained. The left auricle is empty and presents a normal appearance.
The wall of the left ventricle measures l7/8th inches at its greatest thickness. There are
numerous subendocardial extravasations dotted over the whole extent of this cavity, but
they are much more numerous on the upper half, although the largest and most extensive
hæmorrhages are as usual situated on the surface of the musculi-papillares.
Abdominal Cavity is free from fluid.
Liver weighs 14 lbs. 7 ozs., is enlarged, and presents signs of old perihepatitis,
especially of the surface of the left lobe. On section, the organ is found to be full of blood
which exudes from the cut ends of the vessels and a section of the tissues resembles a
nutmeg in appearance.
Spleen.—Weighs 1 lb. 9 ½ ozs., is small,but presents very numerous sub-capsular petechias
of a bright red colour. On section the tissue is firm and healthy in appearance.
