ERRATA 



By a peculiar accident Mr. Korstian's article was printed twice, 

 namely, on pages 177 to 192 and pages 408 to 424. The first 

 printing contained a few typographical errors, which do not 

 occur in the second printing. 



In the article by Mr. Haasis a few errors occurred, which do 

 not influence the sense, or else correct themselves.
