A MECHANICO- PHYSIOLOGICAL 

 THEORY OF ORGANIC 

 EVOLUTION. 



SUMMARY. 



IN this summary I shall in general pursue a 

 course the reverse of that which my main work 

 follows.* I shall proceed from the primitive, unor- 

 ganized condition of matter and endeavor to show 

 how organized micellar substance has arisen in it, 

 and how, from this micellar substance, organisms 

 with their manifold properties have arisen. Since 

 such a synthesis of organisms out of known forms 

 of matter and force is still far removed from a 

 conclusion strictly in accord with physical law, the 

 process becomes comprehensible and obvioiis only 

 by exact knowledge of the discussion that has 

 preceded. Although the synthetic method reveals 

 more clearly the weaknesses of the theory than do 

 analytic investigations, yet I considered it helpful
