CYSTIC TUMOUR 01' THE PROSTATE GLAND IN A DOG. BY W. R. DAVIS, M. R.C.V.S., NEW VETERINARY CO LLEGE .
A LARGE mastiff, the property of an Edinburgh gentleman, was brought to the College on July I5th last for treatment. The history of the case was as follows : The dog was ten years old, and had been in the present owner's possession since it was a pup. It had never suffered from any illness until about May, when it was noticed that occasionally the dog would, when defecating, remain for a long time in the position to accomplish this act, and the nose would be held high in the air; it would strain and utter plaintive howls. When first observed, this would happen perhaps twice a week; soon it took place at shorter intervals, the howling becoming louder and the straining more violent. A "doggy" man, who was consulted, stated that the dog had piles, and this, too, was the opinion of the owner. Under this supposition some treatment was adop~ed, but as no improvement took place, and as the cries of the creature were a source of alarm to the neighbours, the dog was brought to the College and left to b e treated, and if nothing could be done to cure him, he was to be destroyed. An enema of warm glycerine was followed by a copious dejection of perfectly normal freces; there was no trace of blood. After defecating, the dog kept in position, and with its head up gave utterance to a series of prolonged but not very loud howls. Directly afterwards it walked round the yard and urinated two or three times, but instead of lifting the hind-leg in the customary manner, the patient sat down in the posture assumed by the bitch when passing urine. The owner, who was still present, told me that this pecuiiarity had only bee n noticed since the commencement of the present trouble, previous to which the dog had always raised the l~g when urinating. On passing the oiled finger into the rectum, the mucous membrane was found to b e quite smooth, so that hremorrhoids had evidently nothing to do with the symptoms. It seemed to me tha.t the rectum was dilated; its walls were tense, as if dra'.Yn forwards. Deep in, the gut suddenly narrowed and curved to the right, while to the left a rounded mass could just be felt. The dog struzgled very violently and persistently during these manceuvres. I informed the owner that I thought the dog had a tumour near the bladder, and that the interference was as much with passing of urine as with defecating. The
The Veterinary J OUrtwl. patient was left for further observation. Care was taken, by dieting and by occasional enemas, to keep the fcece soft, while plenty of exercise was given. At first, some improvement seemed to follow thi s treatment, but after three weeks it was decided to have the dog destroyed. This was done by injecting a drachm of Scheele's hydrocyanic acid up the nostril. (This is a very good way to poison dogs, as with a muzzle on it is sometimes difficult to get the liquid into the mouth; the animal is sooner dead and less aci d is n eeded.) On making a post-mortem examination, all t he organs were found to b e normal with the exception of the bladder and prostate. The latter was converted into a large rounded tumour.

The body was rigid, and the animal stood with its legs like props under it; hind and fore perfectly straight and stiff.
