“Ten days ago I was bitten by a large cobra, from which I was collecting venom. I had only some very old serum in the laboratory, but I immediately gave myself an injection of 18 c.c. Three hours after being bitten I felt faint, my legs became paralysed, and I was seized with vomiting. In the meantime, fresh serum had been obtained at a chemist’s, and I received an injection of 10 c.c. The symptoms improved very rapidly, and an hour later I felt perfectly well. I applied no local treatment, relying altogether upon the serum.” XI.--Case reported by Dr. Angier, of Pnom-Penh (Cambodia). “At 11.30 one night in April, 1901, His Majesty, the second King of Cambodia brought to me in a carriage one of his wives who, when crossing the courtyard of the palace at about 8 o’clock, was bitten by a snake, which she said was a cobra (in Cambodian _Povek_). “The bite was situated in the lower third of the leg, in front of the internal malleolus. The patient complained continually; she was suffering greatly from the leg, which was swollen as high as the knee. Great lassitude. An injection of 10 c.c. of antivenomous serum was given, half in the leg and half in the flank. The wound was washed, squeezed and dressed. Twenty minutes later the pain had ceased, and the patient went away, feeling nothing more than a slight dulness in the injured limb.” B.--Naja haje (Tropical Africa). XII.--Cases reported by Dr. P. Lamy, of the Houdaille Expedition. “Lamina, a Senegalese, bitten on the outside of the left thigh, on February 18, 1898. Treated with serum. Recovery. “Momo Bolabine, bitten in the heel on April 20, 1898. Ten c.c. of serum. Recovery.” XIII.--Case reported by Dr. Deschamps, of Thiès (Senegal).
