Vlll PREFACE. 



No attempt has been made to produce anything like a strictly 

 literal translation of the German text. Wherever any deviation 

 from the actual words of the original has seemed to me to bring 

 out the meaning of the Author more clearly in English, I have 

 allowed myself a very free hand, in the hope of thereby attaining 



more useful results.
