Autopsy at 1 P.M., two hours after death. Body weight 26 lb. The body is some-
what emaciated, and on section, no sub-cutaneous adipose tissue is seen. The cymphatic
glands of the neck are somewhat increased in size.
The pleural cavities are free from fluid and there are no pleuritic adhesions.
The lungs are fully distended with air, the left organ being the seat of hypostatic conges-
tion. On section, the tissues present a healthy appearance.
There are 15 c.cm. of a clear straw-coloured fluid in the pericardial sac.
Heart.—The base is surrounded with a semi-solid jelly, in place of the fat usually found
in that position. The external surface of the organ is free from extravasations of blood or
small petechiæ. On section, the internal surface of the endocardial sac is free from extravasa-
tions, and the valves are healthy.
The peritoneal cavity is free from fluid.
Liver weighs 3 lb 13 ozs., somewhat small. Glisson's capsule free from old or recent
signs of inflammation so frequent in equines which have succumbed to Surra. On section
the tissues present a healthy appearance.
Spleen weighs 14 ozs., normal in size and consistency. On section, tissues present a healthy
appearance.
Kidneys.—Right weighs 6 ozs., left 6 ozs. The capsules strip easily. On section, tissues
healthy in appearance.
Rumen, Reticulum, Omasum and Abomasum healthy.
Large and small intestines present healthy appearance.

Buffalo No. II, aged 2½ years, was kept under observation for a period extending over
45 days previous to the commencement of the experiment. On January 14th, 1897, the
animal was inoculated with Surra in the ear. For this purpose a minute incision was made in
the skin covering the tip of the right organ, and a minute drop of blood containing a few
Hæmatozoa, taken from Buffalo No. I, was inserted between the edges of the wound. No local
manifestations of any kind were observed to follow the inoculation, but on the morning of the
20th, after a latent period of a little over five days, the Hæmatozoon appeared in small numbers
in the blood. The time which elapsed between the first appearance of Hæmatozoon and death,
viz., 46 days, was made up of seven paroxysms lasting 15, and seven intermissions lasting
31 days. During the course of the disease the animal lost flesh, and before death took place
became emaciated, in spite of the appetite which was present until several days before the
animal succumbed.
