mathematical problems. The mind (as the Z-system 

 of the brain), psychic power, and thought — all must 

 be rated quantitatively; but obviously, mathematics, 

 and only mathematics, can determine the value, 

 numerical value, of — 



1. Elementary units that are crowded (organized) 

 within an atom of a brain cell (spelling conscious- 

 ness), as compared with the number of elementary 

 units that constitute the Z-system of an atom of an 

 ordinary body cell (spelling mere sensation) of the 

 same individual; 



2. The difference (in brain capacity) between 

 man and apes; 



3. The difference (in brain capacity) between 

 one race and another race; 



4. The difference (in brain capacity) between 

 one individual and another individual. 



An entirely new and very wide field for mathe- 

 matical effort is opened up; since according to the 

 theory all that concerns the organism which is not 

 amenable to laboratory treatment, is subject to 

 exact mathematical treatment at the hands of one 

 versed in atomic physics. The psychologist (and 

 the biologist) of tomorrow will have to be thor- 

 oughly informed in atomic physics, and skilled in 

 the use of mathematics. 



Once psychology adopts the methods that are
