REMARKS. 



Injected intravenously 0.005 gram dried Cobra venom dis- 

 solved in I c. c. distilled water with a little sodic chloride 

 and filtered. 



A clot was probably beginning to form in the canula, and no 



dependence is to be placed upon the after record. 

 Struggles. Clot in canula. 

 Dead. 



Injected intravenously 0.015 gram dried Cobra venom dis- 

 solved in 1 c. c. distilled water.

REMARKS. 



Injected intravenously 0.005 gram dried venom of the Daboia 



RusseUii dissolved in 0.5 c. c. distilled water. 

 Pressure falling. 



Violent general convulsions.
