THE VENOM OF HELODEKMA. 



Fig. 37. — Rabbit 17, Experiment 3. Amotrnt of venom slightly larger th.in in preceding experiment; if there was a 

 leucocytosis, it occurred at times other tlian when counts were made, 1 and 2 days respectively after 

 injection. 

 Rabbit 17, Experiment 4, Amount of venom administered again increased. Slight rise in number of leuco- 

 cytes on third day after injection was probably not due to action of venom. It is difficult to explain why 

 no leucocytosis was found in this case; it may have occurred during the night.
