VI PREFACE. 



The author is fully aware that this method of treatment only 

 enables him to touch the fringe of the subject, as it were, but 

 he has been content to deal with it in this way, as it appeared 

 to be the kind of information that would most nearly meet the 

 requirements of the majority.
