$granular Ij'mpli, ueartho snrtace, extending- in one instance to half an iiu'li in clei)th. There was also marked evidence of tatty degeneration. The gall bladder was the seat of extensive, ramified redness on its inner snrface. The spleen, of a dark purplish tint, weighed six and a half pounds. Wherever an incision was made, its softened pulp exuded without pres- sure. The kidneys, paler than usual in this disease, weighed three and one- (piarter pounds. They were free from ecchymoses. The urinary bladder was much distended with bloody urine. The cerebro-spiual meninges were intensely/congested. The gi-ay matter of the brain was reddened, and the puncta vasculosa in the oval centers very marked. Observation XVIII, August 24, 1868,—Black steer; the property of ]\[essrs. Palmer and Perry. Died dimng the day. Post-mortem exam- ination at 6 p. m. Eespii-atory passages normal; cadaveric congestion of left lung. On oiJening the pericardium, the heart was found exten- sively ecohyraosed at the base of the right ventricle, and over the origin of the pulmonary artery. The right cavities contained a little dark, semi-fluid blood. The left side was nearly em])tj, but on the columure carneffi of the ventricle there was a dark pui'plish tint of the endocardium from extensive extravasations of blood in and beneath its structure. The digestive organs anterior to the true stomach were sound. The car- diac end of the abomasum was of a diffuse red color. The mucous membrane of the pyloric end was of normal color, wherever it was not eroded, but it was studded with between twenty and thirty abrasions of the ei)ithelium, exposing the vascular membrane in patches varying from oue-foiuth to one and one-half inch in length, and usually longer than broad. The duodenum was turgid with bile. The jejunum was extensively ecchymosed on its inner surface. The large intestine healthy, except some extravasation on the rectal folds. The liver and gall bladder, of general normal look, but congested, weighed twenty-seven pounds. The gall bladder was distended by inspissated bile. The gland itself was softened by fatty change. The* spleen, dark and softened, weighed seven and one-fourth pounds. The kidneys were intensely congested, but not ecchymosed. The bladder was full to repletion of bloody urine, but its coats were normal. Dark- ness precluded the examination of the brain and spinal cord. Observation XIX, August2G,18G8.-^Two-year-old roan steer; the prop- erty of Mr. Richard Callahan, near Abilene. Organs of respiration healthy. Heart flabby and blood-stained on the posterior ventricular fiuTow. In- terior of right side unchanged, but on the septum, and fleshy pillars in the left ventricle, were exteiisive ecchymoses. On opening the abdomen the peritoneum was found studded witli punctifonu ecchymoses. Organs of deglutition and first three stomachs normal. The cardiac$
