when the lint was removed, that there had been a development of encephaloid granulations, which increased so rapidly that I decided to use electrolysis, and applied three needles to the mass attached to the negative pole of the battery; the positive pole was placed in the palm of the hand, 6 cups were used for five minutes, 8 cups for two minutes, and 10 cups for five minutes-as much as could be borne by the patient. The next day the growth was larger than the day previous, and I placed an electrode 1 inches length by inch wide upon the mass, and gradually increased the current from 8 to 16 cups for fifteen minutes; the disk was covered with one layer of lint. After four days I used the electrode bare, and in a week used a still larger electrode, round, 1 inch by diameter, which I pressed into the mass, but the tumor was only shrunken a little; and the next day after, it would be as large as before; after a week of this treatment, the tumor had gained in size. I then took a smaller electrode, inches by, and thrust it deep into the bottom of the cavity, and continued the application for twenty-five minutes; after a week I told the patient that I had gained a little, but could not promise to benefit her; I would try it as long as she would submit to it. She replied, that she would do anything to save her hand, and continued to come, and in a week longer, by daily application of the full power of the battery (16 cups) for twenty-five minutes, the diminution of the growth was so great that I prognosticated a suppression of the disease. From the 1st of May to July, the applications were made every second day, at which date there was cicatrization; the patient called only twice a week. In August the patient was using the hand to sew, the thimble being used upon the middle finger. Her arm was greatly fatigued, and the electricity relieved it, she coming once or twice a week till November 15; since which there has been no occasion for any application. In November, 1870, I had the photograph taken which I now present to you; a model in wax was taken by Dr. Nardyz, but the mould being broken I had a second one made last week.

It is now nearly two years (twenty-two months) since the cicatrization, and sixteen months since any application has been made to the case.

REMOVAL OF THE UPPER PORTION OF THE LEFT FEMUR FOR DISEASE OF THE HIP-JOINT.

A. M., male, æt. 6 years, native of Iowa, son of healthy parents, and enjoyed good health until he reached the age of three years, when he was supposed to have received a kick from a playmate on the left thigh. From the date of the injury he commenced to favor the limb in walking, and the lameness was attributed by his attendants to a contusion of the soft parts, and was considered of only temporary duration. He continued to suffer from soreness and pain in the vicinity of left hip-joint, and down the thigh, until about the middle of November, 1868, when a swelling began to show itself on the inner and posterior portion of the joint, and continued to increase in size, accompanying which there was a general depreciating derangement of the system, until February, 1869, when it was opened and caused to discharge not less than eight ounces of purulent fluid. General supportive, unmechanical treatment was administered. The orifice made in opening the abscess continued to discharge sanious matter until July, 1869, when another swelling appeared on the inner and anterior portion of the hip, which opened spontaneously. In October, 1869, another swelling, giving evidence of fluctuation, showed itself, and was opened and discharged a large quantity of pus, not materially different from that which was evacuated on the other occasions referred to. In July and August, 1870, two more abscesses appeared and were similarly treated. At the date when the last collections of pus were discharged, the patient ceased to walk even on crutches, and thereafter became greatly emaciated, suffering from time to time from abscesses around the joint, all of which
