J. SLADE ON MYCETOZOA. 437 



beyond the abyss of geologically -recorded time to the still more 

 remote periods when the earth was passing through physical and 

 chemical conditions, we should expect to be witnesses of the 

 evolution of living protoplasm from non-living matter." May I 

 suggest that that first living form may perhaps have been the 

 remote ancestor of a Mycetozoan ?
