Mr. Blaine and myself used cordially to agree with regard to the treatment of pneumonia, materially different from the opinions of the majority of sportsmen. Epidemic pneumonia was generally fatal, if it was not speedily arrested in its course. The cure was commenced by bleeding, and that to a considerable extent, when not more than four-and-twenty or six-and thirty hours had passed; for, after that, the progress of the disease could seldom be arrested. Blistering the chest was sometimes resorted to with advantage; and the cantharides ointment and the oil of turpentine formed one of the most convenient as well as one of the most efficacious blisters. A purgative was administered, composed of mutton broth with Epsom salts or castor oil; to which followed the administration of the best sedatives that we have in those cases, namely, nitre, powdered foxglove, and antimonial powder, in the proportion of a scruple of the first, four grains of the second, and two grains of the third. Congestion of the lungs is a frequent termination of pneumonia; and in that congestion the air-cells are easily ruptured and filled with blood. That blood assumes a black pulpy appearance, commonly indicated by the term of 'rottenness', an indication or consequence of the violence of the disease, and the hopelessness of the case. A different consequence of inflammation of the lungs is the formation of tubercles, and, after that, of suppuration and abscess, when, generally speaking, the case is hopeless. A full account of this is given in the work on the Horse. Two cases of pneumonia will be useful: Oct. 22d, 1820. A black pointer bitch that had been used lo a warm kennel, was made to sleep on flat stones without straw. A violent cough followed, under which she had been getting worse and worse for a fortnight. Yesterday I saw her. The breathing was laborious. The bitch was constantly shifting her position, and, whether she lay down or sat up, was endeavouring to elevate her head. Her usual posture was sitting, and she only lay down for a minute. The eyes were surrounded, and the nose nearly stopped with mucus. V. S. [Symbol: ounce] viij. Emet. Fever-ball twice in the day. 23d. Breathing not quite so laborious. Will not eat. Medicine as before. Apply a blister on the chest. 24th. Nearly the same. V. S. [Symbol: ounce] vj. Bol. utheri. 26th. Decided amendment. She breathes with much less difficulty. Less discharge both from eyes and nose. Bol. utheri. Nov. 7th. Sent home well.
