68 THE VENOM OF HELODERMA. 



The possibility that the local symptoms are due to the effects of micro- 

 organisms which enter the wound either at the time of biting or after the biting 

 can not be excluded, since in our experiments the venom obtained by allowing 

 the helodermas to chew the sponges was not sterilized before injections. 



The following records of autopsies performed on animals which had been 

 injected with heloderma venom show some of the appearances which have 

 been mentioned above :

 intestine, no hemorrhages, and no self-digested areas of stomach. 

 Guinea-pig 99, 400 g. 



June 21, 2'' 00'" opened abdominal cavity and examined intestmes; sewed up wall and 

 injected subcutaneously 0.05 c.c. of venom; no symptoms. 2'' 35"' injected
