“In the month of October, 1898, I was called to a native, a local constable, who had just been bitten by a Naja. The Ouoloffs of Senegal are much afraid of the bites of this reptile, since they are generally fatal. In this case the man had been bitten in the forehead by a snake, which was coiled up in his bed, as he was placing his head on the pillow. Being in the dark, he got up greatly frightened, lit a candle, and saw the snake glide from his bed and escape through the half-open door. I arrived a few minutes after the accident; the constable already felt very weak, and complained of nausea and of pains in the head and back of the neck. In the middle region of the forehead I found two adjacent wounds, around which the tissues were œdematous. I washed the wounds with a solution of permanganate of potash, and had a telegram sent to St. Louis asking for antivenomous serum. Half an hour after the bite, the patient was seized with vomiting and cold sweats. At 6 a.m. on the following day there was considerable œdema of the face and dyspnœa, while the pulse was small and intermittent. The patient, who had not slept, was dull and depressed. He vomited a little milk which I tried to make him take. Forty hours after the bite the patient, who was already paralysed, became comatose; the face and neck were enormously swollen. The dyspnœa had increased; it was difficult to hear the respiratory murmur; the pulse was thready, slow, and intermittent; the skin was cold; the temperature, taken in the axilla, was 35·8° C. At this moment the serum asked for arrived from St. Louis. I injected into the buttock the only dose that I possessed, 10 c.c. The coma persisted throughout the evening and during part of the night; at 6 a.m. on the following day, fourteen hours after the injection, the patient awoke and said that he felt quite well. The œdema of the face and neck had diminished, that of the eyelids had disappeared. Three days later the constable returned to duty.” XIV.--Case reported by Professors H. P. Keatenje and A. Ruffer (Cairo).
