coloured exudation with a few sub-pericardial ecchymoses dotted over it. On

vening tissue greyish-brown in colour. On section cortical portion the seat of
the same kind of petechiæ as described externally. Medullary portion presented

of the organ, and a small one on the lateral wall. Small intestines. Several

No. LXXVII.—A Persian gelding, aged 13 years, was purchased 26th
November 1886. Attacked with fever 20th November 1892. The Surra
hæmatozoon was discovered in the blood 27th November 1892. On the evening
of the 29th November an eruption of Urticaria appeared, but again disappeared
after the same night. It however recurred on the mornings of the 30th
November, 1st, 2nd and 3rd December, fading gradually away towards 6 P.M. on

morning the animal was submitted to a treatment of Arsenic. The temperature
on the morning of the 2nd December had fallen to within normal limits and
remained so until the evening of December 31st. From the latter date until January

Autopsy.—Body somewhat emaciated ; complete absence of swelling and
oedema from the abdomen and extremities. On section all the tissues stained
yellow in colour. Thorax.—There was no fluid in the pleural cavities, and no
pleuritic adhesions. Lungs.—Both apices and anterior inferior borders were the
seat of localized emphysema. A few sub-pleural extravasations of blood were
dotted over the organs. Pericardium.—The cavity of the sac contained 4 ozs. of
a turbid, orange-coloured fluid. Heart.—Enlarged. Base—Surrounded by exu-
dation. External surface was free from extravasations. Internal surface.—
Endocardial lining of cavities stained a yellow colour ; no sub-endocardial extra-
vasations. Valves.—Healthy. Abdominal cavity was free from fluid. Liver.—
Size normal ; old perihepatitis. On section tissues presented a healthy appear-
ance. Spleen.—Enlarged to double the normal size ; sub-capsular petechias. On
section tissues firm. Pathological change resembled amyloid degeneration to
naked eye. Kidneys.—Cortical portion dark in colour. Stomach—Small and
contracted. Villous portion presented a greenish yellow colour ; mucous mem-
brane corrugated, congestion between the ruga3; no ulceration. Spiroptera
tumour the size of a small hen's egg invading the fundus of the organ. Small
Intestines.—Injected more or less in entire length, small patch of extravasation
8 feet from Ileo-cæcal valve ; Peyer's patches were somewhat œdematous, but not
ulcerated. Large Intestines—Deeply congested patch, but no ulceration. Colon
and Rectum presented a healthy appearance. Brain.—Superficial veins congest-
