INHERITANCE 241 



spite of that remain what it was. There cannot be, on the 

 other hand, any sort of machine as the real foundation of 

 the whole of an harmonious system, including many cells 

 and many nuclei, because the development of this system 

 goes on normally, even if its parts are rearranged or partly 

 removed, and because a machine would never remain what 

 it had been in such cases. 



If our analytical discussions have thus led us to establish 

 a typical kind of vitalism, it follows that we can by no 

 means agree with Wilhelm Eoux in his denomination of 

 the analytical science of the individual form and form- 

 production as " Entwickelungsmechanik," " developmental 

 mechanics," a title, which, of course, might easily be 

 transformed into that of " morphogenetic mechanics," to 

 embrace not only normal development, but restitution and 

 adaptation too. We feel unable to speak of " mechanics ' 

 where just the contrary of mechanics, in the proper meaning 

 of the word, has been proved to exist. 



Names of course are of comparatively small importance, 

 but they should never be allowed to be directly misleading, 

 as indeed the term " Entwickelungsmechanik " has already 

 proved to be. Let us rather say, therefore, that we have 

 finished with this lecture that part of our studies in biology 

 which has had to deal with morphogenetic physiology or 

 physiological morphogenesis. 



Once more we repeat, at this resting - point in our 

 discussions, that both of our proofs of life-autonomy have 

 been based upon a careful analysis of certain facts about 

 the distribution of morphogenetic potencies in two classes 

 of morphogenetic systems, and upon nothing else. To 

 recall only one point, we have not said that regeneration,
