Case 1.—R., colored, age 21, had been sick three weeks with specific pelvic suppuration. She had no symptoms of intestinal obstruction or of nephritis. She had the usual preliminary treatment incidental to laparotomy for pyosalpinx. Salts were administered freely and acted well the day before operation. Her urine was examined on entering the hospital and again the day of operation and pronounced free from albumen. A microscopic examination was not made. The operation was made on June 6 at 10:30 a.m. Everything passed off in a satisfactory manner. Intestinal adhesions were not difficult to overcome. The patient was placed in the Trendelenburg posture and every precaution was taken to complete the operation in a thorough and satisfactory manner. The pelvis and lower abdomen was flushed with rather more than the usual care, as quite a large quantity of pus had escaped in the removal of the greatly distended pus sacs.
