Autopsy at 9 A.M., 27th September 1892.
The body is well nourished, the right cornea presents a milky appearance, and the left is not perfectly clear.
There is no swelling or œdema at the seat of inoculation, but on removing the skin, two glands are observed ½ inch in
length, lying close to the symphysis-pubis, one on either side. On section, these glands are pale in colour.
On opening the thorax, a certain amount of yellow-coloured exudation is observed lying behind the sternum
principally at the ensiform cartilage.
Lungs.—There is localized emphysema at the apices of both organs, and numerous extravasations of blood, somewhat
circular in form, and varying in size from ⅛th to ½ an inch in diameter, are dotted over both organs. The centres of
these extravasations present a dark purple colour, surrounded by a pink zone, nearly ⅓rd of an inch in width. The
general surface of the lungs presents a mottled appearance, a pink matrix, dappled with a dark-red colour, and on
section, the tissues have a similar appearance. On pressure, frothy mucus, containing air, exudes from the cut surfaces.
The pericardial sac contains about an ounce of a straw-coloured fluid, and a few shreds of lymph are attached
anteriorly to the muscular tissue of the left ventricle.
Heart.— Externally, there are no petechiæ visible. On section, the right side of the organ is distended with
clots, dark in colour and somewhat firm; on their removal from the auricle and ventricle, the endocardium appears
pale, but there are no extravasations. The left cavities present the same appearances.
Stomach is small and contracted; on section, the mucous membrane is perfectly healthy.
Liver is large, weighs 12 ozs., the lobules are particularly well mapped out, the general colour of the organ being
of a brick-red, whilst the intervening tissue is of pale-yellow colour. On section, the tissues appear healthy.
The Gall bladder is distended with green fluid.
Spleen weighs 3 ozs, and is considerably enlarged. The surface of the capsule is dotted over with dark purple-
coloured, irregular-shaped extravasations, more especially on the convex surface of the organ. On section, the tissues
are soft and dark in colour.
Kidneys.—The right weighs 1 lb. 5 ozs., left 1 lb. 7½ ozs. The capsules strip easily ; the surfaces of the organs are
somewhat lobulated and pale, almost white in colour in localized spots, whilst they are dotted over with numerous
small purple-coloured ecchymoses. On section, the cortical portions are pale and narrow, and the medullary, of a
pinkish hue. There are no extravasations observed in the calyces.
The intestines present a healthy appearance.
Brain.—The membranes are pale, and the superficial veins contain but little blood. The surfaces of the organ
and the tissues, on section, appear healthy, and there is no fluid in the lateral ventricles.
Eyes.—The right cornea is more or less opaque, the left is slightly fogged. The crystalline lens and vitreous
humour of each organ present a perfectly transparent appearance.
