    which day the animal succumbed, the fever was of the continued type, with daily remissions, but only abortive attempts at intermissions. On admission the urine was found to contain a trace of albumen, but it was absent subsequently. Treatment.—This animal was subjected to a treatment consisting of Arsenic in solution only, and the hsematozoon was absent from the blood for a period of seven days. Autopsy.—Body emaciated; hind limbs slightly oedematous. Thorax.—Both pleural cavities contained a considerable quantity of fluid and presented ex- tensive adhesions between the costal and parietal pleurae. Right lung.—Emphysema at the apex and inferior border; sub-pleural ex- travasations. Left lung.—Dotted over with sub-pleural extravasations ; anterior third, the seat of consolidation, posterior frds was fully distended with air. Pericardium contained 4 ounces of a turbid, amber fluid. Heart.— Base surrounded with gelatinous exudation, dotted over with sub- pericardial ecchymoses, as also a small patch at the apex of the organ. The cavities on the right side were blood-stained. The left auricle presented a healthy appearance. The cavity of the left ventricle, especially on its upper half, was the seat of numerous and extensive sub-endocardial extravasations, al- though the largest haemorrhages were as usual situated on the surface of the musculi-papillares. Abdominal cavity was free from fluid. Liver enlarged; old signs of perihepatitis ; tissues on section presented nutmeg appearance. Spleen, small, numerous sub-capsular petechise. Kidneys.—Cortical portion congested, medullary portion healthy. Stomach.— Cuticular portion healthy, villous portion presented a Spiroptera tumor of some size near the line of demarcation ; otherwise healthy. Intestines presented a normal appearance. No. LXXIX.—A Chestnut Australian gelding, aged 12 years, had been six years in the country. First noticed to be ill on 6th December 1892. The haematozoon was discovered in the blood on the same date. The jever which attained a maximum of 41’3°C. was of the continued type, with marked daily re- missions and intermissions at irregular intervals. The urine from the first contained a large quantity of albumen and continued to do so until death ; at a later period casts appeared together with leucocytes. This animal was subjected to a treatment consisting of Arsenic in solution from the first, which quickly produced an effect on the hsematozoon which was absent for thirteen days out of the seventeen, during which the animal survived. Autopsy.—Body emaciated, some swelling and oedema of the extremities, sheath and under-surface of the abdomen. The visible mucous membranes presented an amber colour, and on section the tissues of the body were stained an orange colour. Thorax.—The pleural cavities each contained a considerable quantity of fluid, but there were no pleuritic adhesions. Lungs.— Both were the seat of sub-pleural ecchymoses, together with emphysema at the apices and free borders. No consolidation. Fericardium.—The sac contained two ounces of fluid. Heart considerably enlarged. The base was the seat of gelatinous exudation, dotted over with a few sub-pericardial ecchymoses, but the muscular structure was free from them. On section.—The right auricle was free from, but the right ventricle presented a few dark-coloured sub-endocardial extravasations which were surrounded by a zone of a lighter colour. Left auricle healthy. Left ventricle, walls hypertrophied. The upper half of the cavity presented extensive, dark-coloured, sub-endocardial extravasations, which were particularly well marked behind the 4 chordae tendineae ’ and on the upper portion of both musculi papillares. Abdominal cavity was free from fluid. Liver enlarged, old signs of peri- hepatitis. On section tissues appeared normal. Spleen normal in size, few sub-capsular petechise. Kidneys, both organs tinged yellow ; very numerous, minute sub-capsular petechise covered the whole external cortical surfaces, but on section they did not appear to involve the deeper
