THE ORIGIN AND EVOLUTION OF LIFE 



complex of energies. This is shown in a final scheme of 

 action, reaction, and interaction^ which is an elaboration of the 

 simplified scheme expressed on page i6 of the Introduction, as 

 follows : 



Coordinated Activity of the Organism Within Itself 



ACTION 



AND > 



REACTION J 



of certain parts 



Chemical synthesis 

 proteins, fats, 

 carbohydrates 



Heat and Motion 



Nutrition, digestion 



Respiration 

 oxidation, etc. 



Secretion 



Circulation 



Muscular and Skeletal 

 system, etc. 

 organs of locomotion 



Reproductive system: 

 ovary and testis tis- 

 sues surrounding 

 heredity-germ cells 



All other phenomena 

 under the laws of 

 Transformation, Stor- 

 age, and Release of 

 Energy. 



INTERACTION 



Physicochcmical Agents 

 Catalyzers 



enzymes 

 Internal secretions 



hormones (accelerators), 



chalones (retarders), 

 Nervous system 



accelerators, retarders, 



inhibitors 



Functions of Organs 

 Balance, Equilibrium 



arrested development 

 Acceleration 



growth, development 

 Retardation 



atrophy, degeneration 

 Correlation 

 Compensation 



reciprocal atrophy 



and hypertrophy 



ACTION

[ REACTION

Reproductive system: 

 ovary and testis tis- 

 sues surrounding 

 heredity-germ cells 



All other phenomena 

 under the laws of 

 Transformation, Stor- 

 age, and Release of 

 Energy. 



The eternal question remains, How do these energy phe- 

 nomena which govern the life, form, and function of the organ- 

 ism interact with the supposed latent and potential energy 

 phenomena of the heredity-germ cells? As stated in the Pref- 

 ace and Introduction, this question can only be answered by 

 experiment. There is no proof at present. 



^ This notion of coordinated activity is particularly well expressed in Mathews's 

 Physiological Chemistry (191 6), a volume which came to the author after this work was 

 written (see Appendix, Notes V and VI).
