vi PREFACE 



few omissions to avoid unnecessary repetition. A 

 certain amount of repetition will, indeed, still be 

 found to exist, as somewhat similar ground is, in 

 certain instances, traversed in the course of two 

 separate articles. To have avoided this, would 

 have entailed practically re-writing some, or the 

 total omission of others ; and it was consequently 

 decided to print the entire series almost as it 

 stood.
