Not only is it very far i hava nee of anything that has hitherto 
appeared in the English language, but no other tongue, not 
excepting the German, can to-day offer its equal. The book 
treats of a difficult and complicated subject, but the difficulties 
are approached in a manner adapted to make their mastery easy

theories, and clearly indicates where his conclusions rest on solid 
facts, and where, in default of accurate knowledge, it is for the
