POISON OF SOME INDIAN VENOMOUS SNAKES. 35 



effect, and live days afterwards the snake was in its normal 

 condition. 



Experiment n. — A Dahoia was bitten by a fresh cobra near 

 the tail, the scales having been previously scraped off. The 

 snake bit fiercely and repeatedly. Two days afterwards no 

 effect could be noticed. 



Experiment o. — A large black cobra was bitten in two places 

 1 foot 6 inches from the head, and also on the head, by a large 

 and vicious Daboia. Blood was slightly drawn ; and there could 

 be no doubt that the fangs had penetrated and the poison been 

 inoculated. Six days after the bite there was no change in the 

 snake. 



Experiment p. — A full-grown cobra was bitten by another 

 full-grown, fresh, and vigorous cobra in two places about 

 6 inches from the head, and also in the mouth. They both bit 

 each other freely in this situation, and blood was freely drawn. 

 They were both well a week afterwards. 



Experiment q. — A cobra had 15 drops of his own venom 

 injected hypodermically about 8 inches from the head. • A week 

 afterwards it seemed sluggish ; but this might be from other 

 causes. 



Experiment r. — A cobra had 15 drops of the venom from 

 another cobra injected hypodermically in the same situation as 

 the last. A week afterwards he was perfectly well. 



Effects on Fish. 



Cobra-poison seems to produce paralysis, indicated by the fish 

 turning on its side in the water — and also great excitement, the 

 fish struggling and plunging violently. 



Experiment IX. 



A fish (Ophiocephahcs marulius), about 10 inches in length, 

 was bitten by a fresh cobra at 11.20 a.m. in two places on the 

 dorsal and ventral surfaces. 



11.22.- It turned over on its side in the water. 



11.23. Struggling and plunging violently in the water.
