Spirazines 53 



ing a random state of distribution, whereas in the 

 molecular structure of living matter the orderly 

 arrangement of the atoms along the sides of the 

 polygonal compartments will tend to sort out 

 rather than mix up the molecules or ions within 

 them. The passageways through these polygonal 

 compartments are only about ten Angstrom units 

 in width, which is not sufficient to permit any free 

 flow of fluid therethrough. Since the spirazines 

 which form the walls of these compartments are 

 polar structures, they will render the electric fields 

 within such compartments unsymmetrical so as to 

 facilitate the migration of molecules or ions in one 

 direction but retard them in the opposite direction. 

 The direction of migration of molecules or ions 

 through these compartments may also be con- 

 trolled by side chains extending inwardly from 

 the walls thereof and functioning in a manner 

 similar to check valves. These side chains may 

 be in the form of fat or carbohydrate molecules 

 in the process of formation which have not yet 

 become detached. Since they consist of only sin- 

 gle chains of atoms they will be sufficiently sensi- 

 tive to respond to the approach of individual 

 molecules or ions, and like Maxwell's demons will 

 close or open the passageways through the polyg- 

 onal compartments according to whether a certain 

 ion or molecule approaches from one direction or 

 from the other.
