In tables XV, XVI, XVII, and XVIII the effect of combination hepatectomy and 

 splenectomy are studied. In all four animals the platelet and white cell drop appear 

 to be markedly decreased. X'o definite conclusion can be drawn from the hematocrit 

 changes since we feel that the major surgical procedure was sufficient to alter blood 

 volumes and therefore hematocrits. In tables XVII and XVIII the animals did not 

 show the warming phase rise in platelet count. We feel this was due to the marked 

 trauma the animals had undergone and the resultant extreme cachexia. Figures 2 

 and 3 summarize the results of platelet and white cell counts in control animals, hepa- 

 tectomized animals, splenectomized animals, and hepatectomized-splenectomized ani- 

 mals. Splenectomy alone had little effect, hepatectomy alone a slightly greater effect,
