Some sportsmen are accustomed to 'round' the ears, that is to cut off the diseased part. In very few instances, however, will a permanent cure be effected, while the dog is often sadly disfigured. A fresh ulcer frequently appears on the new edge, and is more difficult to heal than the original one. Nine times out of ten the disease reappears. The Newfoundland dog is very subject to this disease, to remedy which recourse must be had to the nitrate of silver. Spaniels have often a mangy inflammation of the edges of the ear. It seldom runs on to canker; but the hair comes off round the edges of the ear, accompanied by much heat and scurfiness of the skin. The common sulphur ointment, with an eighth part of mercurial ointment, will usually remove the disease. From the irritation produced by canker in or on the ear, and the constant flapping and beating of the ear, there is sometimes a considerable effusion of fluid between the integument and the cartilage occupying the whole of the inside of the flap of the ear. The only remedy is to open the enlarged part from end to end, carefully to take out the gossamer lining of the cyst, and then to insert some bits of lint on each side of the incision, in order to prevent its closing too soon. In a few days, the parietes of the cyst will begin to adhere, and a perfect cure will be accomplished If the tumour is simply punctured, the incision will speedily close, and the cyst will fill again in the space of four-and-twenty hours. A seton may be used, but it is more painful to the dog, and slower in its operation. The ear should be frequently fomented with a decoction of white poppies, and to this should follow the Goulard lotion; and, after that, if necessary, a solution of alum should be applied. To the soreness or scabby eruption, which extends higher up the ear, olive oil or spermaceti ointment may be applied. In some cases, portions of the thickened skin, projecting and excoriated, and pressing on each other, unite, and the opening into the ear is then mechanically filled. I know not of any remedy for this. It is useless to perforate the adventitious substance, for the orifice will soon close; and, more than once, when I have made a crucial incision, and cut out the unnatural mass that closed the passage, I have found it impossible to keep down the fungous granulations or to prevent total deafness.
