The Skin Lesions of Swine Erysipelas
Fyacture of the Skull. THE SKIN LESIONS OF SWINE ERYSIPELAS. BY HENRY TAYLOR, M.R.C. V.S., HAYWARDS HEATH, SUSSEX.
THE accompanying photograph represents a piece of skin taken from the back of a pig, and shows fairly well the rhomboidal figure characteristic of this disease. The photograph is natural size, though, perhaps, this was one of the largest diamond-shaped patches. Although they could be felt in the living animal as slightly raised areas, they came out much more clearly when the pigs (black in this case) were scalded and scraped. Then they appeared as dark red spots on the white ground. These were affected, and the parts of the body involved were the back and sides. On each pig there were a dozen or two of varying sizes and of varying ages. The older ones were fainter in colour, and their well-defined edges had faded, making them appear somewhat circular, similar to the bottom righthand corner one in the photograph. The oldest ones were brown in colour. The best idea of the appearance of the tout ensemble is got by holding the photograph at arm's length.
FRACTURE OF THE SKULL. BY COL. ]. C. BERNE, A.V.D. (RETIRED), PORTSMOUTH.
ON the sth inst., a rare instance of indirect fracture - fracture pa, confrHoup-occurred to a horse of the Army Service Corps. He was one of a detachment stationed at Fort Nelsbn, near Portsmouth. It had been the custom to allow the horses out to graze on the glacis of the fort. Forming, as it were, the back part of the glacis was a brick wall, almost exactly twelve feet high; the shape was a right angle triangle, -only the slope was very gradual. On the day in question, the sentry near the gate of the fort heard a thud, and looking out found that the horse, through some unaccountable reason, had fallen from the top of the glacis referred to-a drop of twelve feet. When seen, he was on his knees, with his head bent between them. He struggled, it was stated, for a short time, fell over on his right side, and was dead in less than a quarter of an hour. I made a post-mortem examination of the carcase the following day. The only external injury was an abrasion on the upper lip, and corresponding to this, a wound on the jaw above the upper incisors. From the accounts given by the sentry who saw the horse immediately after the accident, and the position of the animal's head, I concluded that the cause of death was due to brain injury. This, I found, was the case. There was fracture of the ethmoid bone, with some laceration of the brain substance above the seat of injury; and considerable hremorrhage into the tissue under the seat of the fracture. The first part of the animal that came in contact with the ground was the nose, and this would account for the lesions described.
