Continuing in this wa}^ we secure that the "special" coherence 

 strips get everywhere a finite breadth and that the other coherence 

 strips and the skeleton get ever^- where a breadth zero. The inner 

 domains of the special coherence strips form together a set of points 

 everywhere dense in F\ and ail these inner doinalns have the same 

 boundary.
