mis'ht 111' obtained, for tin; frog at least, in shorter 

 time if the nutrition of the cells were prevented, the 

 frogs were thoroughly bled or the capsules of the 

 ganglia torn off. None of these experiments gave 

 definite results. Sections of both ganglia stained 

 by the above method appear redder than normal. 

 This is presumably due to a clogging of the cells with 

 decomposition products which would normally be car- 

 ried away in the circulation. Stimulated and resting 

 alike show vacuolation, probably the same as that 

 found by Rosenbach in starving dogs. The nuclei in 

 both appear shrunken, but do not show any marked 

 difference in size. 



Results of but a single experiment of this class need 

 be given.

 gave more definite results.
