APPENDIX 55 



inflow) by referring back the possession of auto- 

 maticity to one of the causal factors a spring which 

 has both the inertias that of rest (which accounts 

 for the "latent period") and that of movement 

 which along with elasticity " accounts " for its 

 automaticity. 



Professor Bose says, " On account of the oscillating 

 mechanism, the outflow . . . (is) periodic " The 

 oscillating mechanism oscillates because for one 

 thing it has elasticity a property of matter in- 

 timately related to molecular inertia. 



The "oscillating mechanism" of the physical 

 model is the phasically altering metabolism of the 

 biogens of the living protoplasm : the oscillating 

 mechanism in the one case has physical inertia, the 

 molecules of the protoplasm in their alternating 

 phases of metabolism have functional inertia. 



While thus analysing Professor Bose's illustration, 

 I by no means intend to undervalue what he says 

 as to the factor of absorption of energy, and the 

 holding of it latent which is, undoubtedly, of very 

 great importance as a factor in rhythmicality a 

 factor related rather to affectability and therefore 

 not at present under review.
