, having recourse to mercurial ointment, and trying a solution of the sulphate of copper. With two or three applications we could keep the disease at bay; but with none could we fairly remove the evil. The sulphate of zinc, the acetate of lead, decoctions of oak bark, a very mild injection of the nitrate of silver, — all would do good at times; but at other times we were set at complete defiance.
Another gentleman brought his dog about the same time. This was also a Newfoundland dog. He had always been subject to mangy eruptions, and had now mange in the feet, the inside of the ear covered with scaly eruptions, the skin red underneath, considerable thickening of the ear, and a slight discharge from its base. A seton was inserted and a physic-ball given every second day. The canker lotion had little good effect. Some calamine ointment, with a small portion of calomel, was then had recourse to.
In ten days the dog had ceased to scratch himself or shake his head, and the ear was clean and cool. The seton was removed; but the animal being confined, a little redness again appeared in the ear, which the lotion soon removed.
At the expiration of a month he was dismissed apparently cured; but he afterwards had a return of his old mangy complaints, which bade defiance to every mode of treatment.
Maassen, V. S., Wümemburg, has lately introduced, and with much success, the use of creosote for the cure of canker in the ear.
The first experiment was on a setter with canker in his ear. The owner of the dog had ordered it to be hanged, as all remedies had failed in producing a cure. Herr Maassen prescribed
creosoti 3ss. et spirit, vini rectificat. 3ij
. This mixture was applied once in every day to the diseased part. In a few weeks the dog was completely cured, and has since had no return of the complaint. In a terrier, and also in three spaniels, the effect of this application was equally satisfactory. In some cases, where the disease showed itself in a less degree, the creosote was dissolved in water, instead of spirit of wine. It is always necessary to take away the collar while the dog is under treatment, in order that the flap of the ear may not be injured by striking against it.
