Left Auricle.—Healthy.
Left Ventricle.—There are only a few small sub-endocardial ecchymoses.
Liver.—Dark in colour, dotted over its surface with circular, hard, yellow-coloured bodies. There are several
irregular shaped white patches, the seat of old inflammation of the capsule on the convex surface of the organ. On
section, these yellow-coloured concretions are found varying in size from a pin's head to 1/8" in diameter and invade the
whole tissue.
Spleen.—Small, firm; some small petechiæ on the external surface of the capsule.
Stomach.—Externally, the organ presents numerous vessels, dark in colour and distended with blood clots, whilst
to the attached border of the great omentum an extravasation of blood has taken place between the layers of perito-
neum. On section, the organ contains a certain amount of semi-digested food. The cuticular portion is white in part,
whilst the line of junction between the cuticular and villous portion is stained a bright yellow, and this colour is conti-
nued for 2" on the cuticular side of the boundary line, and then gradually fades. On the villous side of the boundary
line and about 1" from it at the most inferior part of the organ, two ulcers are situated, small in size, 1¼ of an inch in
diameter with irregular edges involving only the mucous layer of the organ, and the second about half the size of
the former, with a circular, well-defined edge; this also only involves the mucous coat.
Kidneys.—Capsules are easily removable; the stellate veins are injected on the inferior portions of the organs.
There are a few circular extravasations about the size of a pin's head dotted over the surface of the cortical portion.
On section, the organs are pale, but there are no extravasations visible.
Bladder.—Healthy.
Small Intestines.—Healthy.
Large Intestines.—Healthy.
Cœcum and Colon.—Healthy.
Nostrils.—Healthy.

REMARKS.
15th.—The animal was inocu-
lated subcutaneously over
the left scapular region
with 2.0 c.c. of blood con-
taining numerous hæmato-
zoa taken from the hearts
of two rats (Mus decuma-
nus) immediately after
death.
16th.—There is a circular
raised swelling at the seat
of inoculation 1.5" in dia-
meter, tender on manipula-
tion. The visible mucous
membranes are clear, and
the conjunctivæ are free
from ecchymoses.
17th.—Swelling increased,
and is now surrounded with
œdema.
18th.—Swelling still further
increased, measures 3.5" in
diameter.
19th.—Swelling and œdema
