THE VENOM OF HELODERMA. 



FIG. 31. Rabbits 1 and 8. Smaller doses of venom were used here than in experiments on rabbit 6; a slight rise in both 



occurred. In rabbit 8 the rise is preceded by a fall. 



Rabbit 9. This rabbit had an initially low leucocyte count; it succumbed to a rather small dose of venom. 

 No rise in number of leucocytes. 



FIG. 32. Rabbit 10. Large dose; no leucocytosis. Some initial fall in number of leucocytes. 

 Rabbit 11. Slight fall followed by a not considerable rise in leucocytes. 



Rabbit 12. Small number of leucocytes observed in beginning of experiment; followed by inconsiderable 

 rise after injection.
