“He was immediately given an injection of antivenomous serum, in accordance with the instructions, and, around the bite, five or six injections of permanganate of potash, 1 in 20. On the next and following days, tense œdema of the arm and left side of the chest. Extensive purplish ecchymosis of the inner face of the arm; no fever. The phenomena gradually diminished, and, on August 17, there was merely a trifling wound where the bite had been inflicted. The patient was discharged at his own request. “Like Dr. Marchand (des Montils), we can certify that the action of Calmette’s serum was rapid and efficacious. The injection did not cause any pain or febrile reaction.” XXXI.--Case reported by Dr. Blin, of Dahomey. “On March 5, 1906, native hospital attendant C., while gathering vegetables in the hospital garden, was bitten in the right hand by a _Cerastes_. The bite was inflicted in the tip of the index finger. Ten minutes later a ligature was applied to the base of the finger and another to the upper arm, and as soon as we saw the man, which was after the lapse of about an hour, he was given an injection of 10 c.c. of antivenomous serum. The patient complained of feeling cold and vomited. The axillary temperature was 36·1° C.; the pulse was weak, irregular, and rapid. The finger and hand were swollen. A few minutes later we gave a second injection of serum. Until evening (the accident took place at 11 a.m.) the patient suffered from nausea, but sweating set in, and at 7 o’clock the temperature had risen to 36·7° C. The feeling of depression was much less. On the following day the symptoms had disappeared, and forty-eight hours afterwards the patient returned to duty.” K.--Bitis arietans (Puff Adder).
