BY C. W . TOWNSEND, M.R. C.V. S., LONG STANTON, CAMBRIDGE.
THE subject was a Black Shire Filly, aged 9 months. My attention was first drawn to a swelling about the size of an orange, situated in upper part of the temporal fossa near to the base and front of the off ear. Upon examination I discovered a small hole upon the outer surface of the conchal cartilage , about midway between the tip and the base, and manipulation of the swelling caused a profuse discharge of pus from the opening, thereby proving that a connection existed between the two lesions. Passi ng a probe down the canal as far as it would go without exerting any undue pressure, its point came in contact with something hard; this I diagnosed to be a foreign body of some kind. With the owner's consent I decided to operate to deter-
mine the cause of this abnormality, and after washing , disinfecting, and removing the hair from the area, I made an elliptical incision into the swelling in the temporal region . A quantity of white creamy pus exuded from the opening, and further examination of the interior of the cavity revealed a harden ed body, the latter being enclosed in a thin membrane firml y attached by its base to the underlying structures, this making its removal a matter of some difficulty. After removal I thoroughly scraped the area of attachment with a curette, then washed out the cavity with a weak solution of iodine. I now turned my attention to the sinus leading to the ear, which I thoroughly cleansed. The wound did not require much after-treatment, and a small scar is all that remains to mark the seat of the original lesion. I enclose a photo of this dentigerous cyst, which in shape, size, and structure is not unlike a molar tooth and measures barely 2 inches in

length. The small piece (marked with a cross) was at time of removal only ha lf attached to the main cyst at its free end , and this portion very much resembles the so-called Wolf's tooth. Re1llarks .-I have never met with one so large before, a nd I believe their occurrence in equines is somewhat rare. No doubt the cy st was congenital and the temporal swelling would have broken in tim e spontaneously, but it seems rather peculiar that the formation of pus should have been so slow.

THE patient was a pedigree fox-terrier dog puppy, aged eight months. History.-Catarrhal diarrh rea of a persistent character for about a fortnig ht, appetite good, no vomiting or stomach symptoms, and entire absence of respiratory catarrh, and the puppy did not appear to owner to have any abdominal pain further than a const ant desire to empty the bowels. SYlllptoms.- When broug ht for treatment the bowel was prolapsed about 8 inches, and was in a congested and cold condition . When cleansed and returned, per rectum, the intussusception could just be felt on the point of the finger; the bowel remained in position only a short period after being returned. Owing to the constant straining at each evacuation the length of bowel increased. Treatment.-External removal by operation was deemed impracticable, as the rectum itself was not implicated . Laparotomy was performed under A.C.E. mixture, and the abdomen opened under antiseptic con.d itions in the posterior median line. The intussusception was reduced by gentle mechanical traction, and the bowel sutured to the abdominal wall by three sterilised gut sutures. The bowels were then carefully inflated with a warm, oily enema, which was pressed through the la tely intussuscepted portion by the fingers before closing the abdominal wound , thus removing a quantity of catarrhal mucus and primary adhesions. The abdomen was closed with Lembert's and external interrupted satures, and a supporting bandage placed in position. Salicylate of bismuth and chlorodyne were given internally, and a mucilaginous diet, together with an occa sional dose of warm olive oil, completed an uninterrupted recovery.
