This draught appeared to bring some relief, for the animal remained quiet for some
hours. Temp. 5 P.M. 38.8°C. P. 44. R. 28. Milk mixed with water was given at intervals
to the animal.
18th.—This morning the animal is in a dull and semi-somnolent condition; the draught
was repeated at six o'clock, when the Temp, was 3S°C. P. 40. R. 16; but as the symptoms
were again becoming pronounced, a second dose was administered at 1-30 P.M., when the
temperature was found to be 39°C. The animal has eaten nothing, but milk and water has
been given to it at intervals. The hæmatozoon is still absent from the blood. No urine has
been passed up to 4 o'clock P.M. The medicine was again repeated with Spt. Ætheris. Nitrosi.
3ii in addition. Temp. 5 P.M. 39.6°C. P. 48. R. 12. In all eight seers of milk have been
given to the animal during the day, but no grass or corn.
19th.—The animal stands in one position for hours, but has ceased to look round at the
left side; it certainly is improved, and when lucerne grass is placed m its mouth readily eats
it. The pulse is stronger, more feequeut, but regular; the respirations have again fallen in
point of number per minute. Up to mid-day, four seers of milk mixed with water have
been administered. Temp. A.M. 39°C. P. 64. R. 12. The hærnatozoon which has been
absent for twenty-seven days has now been re-discovered, but only one was observed in two
coverglass specimens of blood. The return of the organism is due to the fact that the
condition of the animal rendered it absolutely necessary to abstain from giving the Cinchona
Alkaloids and Arsenic after the morning of the 14th instant, although at that time it was
only taking the ordinary medicinal doses of Arsenic gr. iv and two drachms of the Alkaloids.
Temp. 1 P.M. 39.6°C. No urine was again passed during the day. Milk and water was
given at intervals up to eight o'clock this evening. Two doses of the medicine, have been
administered during the last twelve hours. Temp. 5 P.M. 40.6°C. P. 64. R. 36.
20th.—The animal remained standing during the night, and this morning there is no
improvement in its condition, although it continues to take a fair amount of milk. The
pulse is strong and frequent but regular. The respirations which had become materially
increased last night have now dropped again to normal. Temp. A.M. 39.3°C. P. 76. R. 20.
The hæmatozoa are numerous in the blood. The red corpuscles are pale in colour and have
run together into masses, but the individual corpuscles can be distinctly made out. The
white are more numerous than in the healthy state, otherwise they are unaltered. No urine
was passed. During the day four seers of milk have boon administered, mixed with water,
at intervals of two hours. Subcutaneous injections of Morphiæ (gr.iss) were given at 11 A.M.
and 6 P.M. The animal fell and was unable to assume the upright position after nine o'clock P.M.
Death took place at 3 A.M. on the 21st November.
AUTOPSY.––8 A.M. 21st November 1892. The body is somewhat emaciated, but there
is a total absence of oedema from the extremities and the under-surface of the abdomen.-
Thorax.—There is no fluid in the pleural cavities and there are no pleuritic adhesions.
Lungs.—There is localized emphysema at the apices and along the free edges. The-
surfaces of the organs are thickly dotted over with ecchymoses lying under the pleuræ and
are for the most part circular in contour, varying in size from 1 to 1/6th of an inch in diameter.
On Section.— The tissues present a peculiar marbled appearance, one portion being pink
and the other white in colour, but microscopically no pathological change can be detected
in either portion.
Heart.—The pericardial sac contains three ounces of blood-stained fluid, in which the
hæmatozoon could not be detected microscopically. The external surface of the organ
presents a pale appearance, the muscular tissue looking flabby and fatty. The base is
surrounded with a light orange coloured exudation, gelatinous in character and occupying
the position usually held by the fat. There are some large extravasations of blood lying
beneath the visceral pericardium, more especially along the course of the coronary vessels
and extending for half an inch on either side of them.
The cavities of the right auricle and ventricle are stained a claret colour. There are,
however, no sub-endocardial extravasations present. The valves present a healthy appear-
ance. The left auricle presents nothing abnormal. The walls of the left ventricle are
somewhat contracted and pale in appearance. There are several groups of extravasations
dotted over the Avails—one patch just below the aortic exit; but those best marked are
found lying on the musculi-papillares. On section these latter are found to invade the
tissues to a depth of half an inch.
Abdominal cavity.—The peritoneal sac is free from fluid.
Liver.—Enlarged, weighs 13 lbs. 12 ounces; healthy in appearance externally as also
on section.
Spleen.—Weighs 3 lbs. 1 ounce ; is enlarged to half as much again as normal. There are
a few sub-capsular petechia), especially on the convex surface of the organ. The tissue on
section is found to present a dark colour and a semi-solid consistency.
Kidneys.—The capsules strip easily and are found to be dotted over with small
circular extravasations, dark in colour, lying beneath the capsules, and which on section
are seen to invade the cortical portion to the extent of l/12th of an inch. The rio-ht
weighs 1 lb. 11 ozs., the left 1 lb. 9 ozs.
