tions of blood are observed, chiefly involving the thick portion of the musculi papillares.
The left auricle is full of dark clots, but there are no occhymoses. The left ventricle con-
tains dark blood clot, with a large buff-coloured one running up into the aortic opening.
The endocardial lining is stained by the blood pigment, but there are no extravasations.
The several valves are healthy.
Spleen weighs 11 lbs. 6½ ozs. Enormously enlarged. There are no extravasations on
the surface of the capsule. The tissue on section is firm and healthy in appearance.
Liver weighs 22 lbs. 2½ ozs., is enormous. The organ is dark in colour and presents
several irregular-shaped nodules, yellow in colour, half imbedded in the superficial tissue
under the capsule, and the other half projecting on the surface. On section, the tissues are
dark in colour, but no caseous nodules are visible imbedded in them.
Stomach large, containing semi-digested food. The cuticular and villous portions are
pale but present no ulceration, but there are three small raised lumps lying under the
mucous membrane of the villous portion about one inch on the pyloric side of the line of
demarcation between the two structures. These small raised tumors are formed by the
Spiroptera megastoma and are hard and present a small opening on the summit which, on
section, is circular and communicates with the interior of these irregular cavities. There are
two larvæ of the ' Gastrophilus equi' attached to the mucous membrane of the cuticular
portion.
Kidneys.—Right weighs 2 lbs. ½ oz., left 2 lbs. 3 ozs. The capsules strip easily; there
are no petechiæ. On section, the cortical portions appear pale and the medullary portions
rather darker in colour, but otherwise they appear healthy.
Intestines.—The small intestines are perfectly healthy. The large intestines are per-
fectly healthy. On opening the nasal passages the mucous membranes covering the
turbinated bones are found to be deeply congested and of a dark-purple colour, but no
ulcerations are to be seen.
The points of interest in this case are:—
(i). That the disease was successfully transmitted by the inoculation of 2 c.c. of
faintly yellow-tinged blood serum drawn from the Internal Jugular Vein of Horse
No. XXXVIII, forty-five minutes after death.
(ii). The presence of an Urticaria over the neck, two days after the appearance of the
hæmatozoon in the general circulation, but the absence of the hæmatozoon from
the blood during the persistence of the eruption.
(iii). The pathological sub-endocardial lesions found in the right but which were absent
from the left ventricle, and the tumefied and congested condition of the Schneiderian
membrane accounting for the persistence of the muco-purulent discharge from the
nasal passages during life.
