TOXICITY OF THE BLOOD OF VENOMOUS SNAKES 221 



Summing up what has been stated above, we find that the 

 blood of both poisonous and non-poisonous snakes contains toxic 

 substances, destructible by heating to 68° C, and physiologically 

 distinct from venoms, but like the latter possessing the property 

 of dissolving the red corpuscles of the majority of vertebrates and 

 of producing haemorrhages.
