Autopsy.—12 noon, 25th December 1892.
Body emaciated. There is no swelling or œdema about the body or limbs.
Thorax.—There is no fluid in the pleural cavities, or adhesions of the pleura.
Lungs.—Are small. There are a few lobules, purple in colour, which present an atalectatic condition ; these are
principally situated at the anterior portion of both lungs. The apices or anterior lobules are the seat of emphysema,
as also the inferior borders of both organs. On section, a pale red fluid representing the blood exudes from the cut
ends of the vessels. The tissues present a healthy appearance.
The cavity of the pericardium contains half an ounce of a clear, amber-coloured fluid.
Heart.—Weighs 1 lb. 2 ozs. The base of the organ is surrounded by a light yellow coloured (jelly-like) exuda-
tion which also invades the origin of the great vessels, and is continued down on either side of the coronary vessels.
A few dark red petechiæ are scattered over the surface of the exudation, but both are found to lie immediately beneath
the visceral pericardium. Both ventricles are contracted.
On section.—
The right auricle contains a dark red clot completely filling its cavity. The lining membrane appears somewhat
pale, but there are no sub-endocardial petechiæ.
The right Ventricle presents a healthy appearance. Valves healthy.
The left auricle—Ditto.
The left Ventricle.—Is empty and contracted; there are only three or four sub-endocardial petechiæ the size of pins'
heads.
The abdominal cavity is free from fluid, and there is a marked absence of any adipose tissue.
Liver.—Weighs 3 lbs. 7 ozs. Glisson's capsule is smooth and free from any signs of old inflammation. On section,
the tissues appear healthy.
Spleen.—Weighs 15 ounces. The surface of the organ is pale. There are, however, a few dark coloured, circular
sub-capsular petechiæ present. On section, the tissues appear normal in character.
Kidneys.—The right weighs 9 ounces; the left 9½ ozs. These organs are both surrounded by a layer of yellow
coloured gelatinous exudation, which enters in each case at the hilum of the organ, and surrounds the vessels and calyces
The capsules are adherent in places. The external cortical surfaces are pale in colour, but are free from petechiæ. On
section.—Microscopically, there is nothing to be made out.
Stomach.— On section, contains no food, but about an ounce of a yellow-coloured fluid. The cuticular portion pre-
sents a healthy appearance. The villous portion.—The mucous membrane covering this portion of the organ for a distance
of three inches from the line of demarcation presents a bright rose colour, but there is no loss of continuity, speaking
generally. About the most dependent portion of the organ is situated a raised lump 2.5"×1.5''×1" hard on manipu-
lation, with several small holes on its surface, leading into its interior. On section, this tumour is found to be circum-
scribed, and to lie immediately under the thick internal coat of the organ. It presents thickened wall, with an in-
ternal arrangement resembling somewhat a section of an ant-hill; between the dividing walls are found massses or skins
of fine worms (Spiroptera megastoma).
Dotted over the mucous lining are also twenty-four circular, raised plaques averaging ½ inch in diameter, with
a thickened, pale-looking edge around the circumference of each. Some appear to be covered with the ordinary mucous
membrane; in others there seems to be some slight loss of the epithelial covering, whilst in others again the surface is
cupped, and thereis a thin layer of detritus, lying superficially and covering the loss of continuity of the epithelial coat.
The small Intestines.—Present a few small petechiæ scattered over the surface of the mucous membrane. At a
distance of six feet from the pyloric end of the stomach a small circular and somewhat raised tumour was found ½"
in diameter, pale in colour, and covered by mucous membrane. On section, it presents a small cavity, circular in form
1/8 inch in diameter, and filled with yellow healthy looking pus.
The Cæcum.—Presents a healthy appearance, but there are numerous small " strongyli " attached to its walls.
The Colon.—Several patches of congestion are dotted over its walls, but there is no solution of continuity observable.
Rectum.—Healthy.

COW.
Cow.—Deccani, aged 6 years. Fawn colour, healthy and in good condition, with calf at side, 3 weeks old.
Inoculated subcutaneously with rat's (Mus decumanus) blood, previously passed through Horses Nos. LXII and
LXVII, and Donkey No. II. Hæmatozoon appeared on the 6th day. Four paroxysms of 5, 1, 1, and 2 days, with three
intermissions lasting 55, 18, and 21 days respectively. Re-inoculation with Horse Surra blood 58 days after the last
paroxysm. Hæmatozoon appeared on tho 10th day. Six paroxysms of 1, 1, 2, 1, 1 and 2 days, with five intermissions of
10, 29, 70, 9, and 36 days respectively. Absence of hæmatozoon from last paroxysm to date, a period of 203 days.

The animal was inoculated subcutaneously over the left shoulder with l.0 c. c. of blood, containing very
numerous hæmatozoa taken from the jugular vein of Donkey No. II.
