PREFACE TO VOL. II 



IN pursuance of the plan adopted for the first volume, the 

 present one, corresponding to Th. I, Bd. II of the German 

 Edition, is issued as a book complete in itself. The Editor 

 alone is responsible for the English rendering, and also for all 

 matter enclosed in square brackets. In spite of these additions 

 it has been found possible to compress the text considerably, 

 while adhering strictly to the sense of the original German.
