Injected intravenously the water -venom-globulin from 0.03 



gram dried venom of the Crotalas adamanteus. 

 Pressure falling. 



Clot formed in the canula. 



Injected water-venom-globulin from 0.015 gram dried venom. 



Animal killed by pithing. 



REMARKS. 



Injected intravenously 0.0033 gram water-venom-globulin 

 (= 0.045 gram dried venom) from the dried venom of the 

 Grotalus adamanteus dissolved by the addition of a trace 

 of sodic carbonate. 



Injected 0.0066 gram as in the foregoing. 



Injected a similar dose. 



Killed by pithing. Heart arrested in diastole ; few ecchy- 

 moses ; blood remains fluid after twenty-four hours.
