ment Death is not due to katabolic destruc- 

 tion, but to the failure of the anabolic process 

 which naturally follows it. Nature gives to all 

 organisms the means of ejecting waste material. 

 It is not, therefore, destruction but starvation 

 which causes death. The disease which is not 

 starvation is due to the uneliminated refuse 

 that blocks the access of nutrition or forms 

 noxious chemical compounds. 



The nutriment that is transformed into cells 

 is not all deposited at one part to feed continu- 

 ous growth, but at two or more alternating 

 parts. If growth begins at an undifferentiated 

 cell, additions will be made first on one side 

 and then on the other. The formation of new 

 cells continues as long as nutrition permits this 

 alternating activity. To arrest growth on one 

 side is to arrest it on the other, since one side 

 cannot be continuously anabolic. Let us sup- 

 pose one side to be injured through disruption, 

 and its complexity reduced several degrees: 

 in order for growth to start afresh, the other 

 side must be correspondingly cut; this is ac- 

 complished by means of disruptive discharges 

 which wear away the one-sided growth until a
