Fig 37 —Rabbil 17, Experiment 3. Amount of venom slightly larger than in preceding experiment; i( there woa a 

 leucocytoaia, it occurred at times other than when counts were made, 1 and 2 days respectively alter 



Rabbit 17, Ezperimnil 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 eiplain why 

 no leucocj-tosis w-as found in this case; it may have occurred during the night. 



FiQ. 38.— Doff 1. Leucocytoais followed injection of venom, part of which was given intravenously.
