From table 17 the participation of venom lipase in typical venom-hemolysis 
seems to be excluded. 
According to the same authors, ricin, and crotin in much less degree, possess 
a similar fat-splitting property, somewhat stronger even than crotalus venom. 
Bee venom also seems to have a certain lipolytic power. 
It is most desirable to investigate the thermal and chemical resistances of 
the lipolytic ferments of snake venom and other toxins in order to elucidate 
their importance as factors in the general toxicity of these substances.
