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, tlie scales having been previously scraped off. The 

 snake bit fiercely and repeatedly. Two days afterwards no 

 effect could be noticed. 



Experiment o. — A lari^^e black cobra was bitten in two places 

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

 and vicious Dahoia. 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 ]). — 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 coltra had 15 drops of his own venom 

 injected hypodermieally 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 hypodermieally 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.
