 living substance from the amoeba onwards." 

 " Protoplasm cannot be thought of merely as 

 a solution of mixed colloids and saline electro- 

 lytes. It must consist of aggregates or clusters 

 of molecules of various dimensions and possess- 

 ing a consistency which no solution could show, 

 inasmuch as a solution would possess viscosity 

 and cohesion equal in every direction. The 

 amoeba if merely a drop of colloid solution 

 would, like a drop of any jelly, gradually, 

 melt away into the surrounding water by the 

 operation of ordinary liquid diffusion. The 

 amoeba has extensibility and retractility, and 

 therefore cannot be an ordinary solution." 

 " Those who accept the purely materialistic 

 doctrine as to the origin of life have before 

 them the necessity of establishing a vast 

 number of facts before such doctrine can be 

 made generally acceptable to the scientific 

 world. The progress which has been made in 

 the desired direction is far from being as yet 

 a justification for the pronouncements which 

 have within the last few years found their way 

 into print and which have too much the air 

 of being uttered ex cathedra " (pp. 463-8).

bio-chemist renders him a peculiarly valuable 

 witness on this point, shall conclude the list.
