Postscript. 



As the publication of my paper has been so unduly 

 postponed and interrupted an explanation is necessary: 

 The manuscript was sent to the press in the spring 1914. 

 I received the first proof at the end of 1915 and had 

 hoped to have the paper published in the beginning of 

 1916. But the great fire in Bergen in January 1916, 



which caused the destruction of the printing works, made 

 this impossible. Later the difficulties of war have pre- 

 vented it from being printed before now. I have ac- 

 cordingly not been able to take into consideration the 

 literature published after the beginning of 1914.
