An Ophiophagus Elaps, nine feet six inches long, and seven inches in circumference, arrived from Kangoon yesterday. It seemed in
when roused; is just about to cast its epidermis. Experiment No. 1.?At 11-50, a pariah pup one-fourth grown, was bitten in the thigh, the snake being made to close its jaws on the part. 11-51.?The dog much excited, but apparently not in any pain. 11-52.?In a state of general tremor; defecation. 11-55.?Fallen over paralysed. 11-56.?Convulsed. 11-58.?? Dead?in eight minutes. The body was examined soon after, death. The blood coagulated in a minute and a half after re moval from the great vessels, into a peculiarly firm clot. The dog never gave the slightest indication of suffering; its death even
very quiet and free from pain. Experiment No. 2.?A full-grown pariah dog bitten on the thigh by the same Ophiophagus at 12. The snake was made to close its jaws as before on the part. 12-2.?Staggers, being weak in the hind leg. 12-4.?Standing up, but seems lethargic; head drooping; no expression or sign of pain; when made to walk, does so with difficulty : limbs seem weak, or to be in a state of ataxy. 12-9.?In the same condition : breathing deep, head drooping to the ground ; seems unconscious of anything; complete locomotor ataxy. 12-20.?Limbs now seem paralysed ; singular freedom from any expression or look of suffering. 12-26.?Slight convulsive movement of muscular system generally. 12-30.?Lies quite motionless; expression of eye natural. 12-31.?Slight convulsions of muscular system generally. 12-34.?Involuntary discharges; heart still beats, no respiration, convulsive waves over the whole body. 12-37.? Appears dead, but the heart still acts irregularly. 12-38.? Dead?in thirty-eight minutes. There was no salivation in either of these dogs. The sympwas
toms, were like those of cobra poisoning; if any difference, death was quieter, and free from suffering. Body examined after death : blood coagulated very firmly on removal from the body. The snako is about to shed its epidermis; it i3 sluggish, and may be sickly, but yet the poison was very active; however, so far as these two experiments show, it is not more active or fatal than that of a full-grown, vigorous cobra.
