Transcriber's note: Minor punctuation and typographic errors have been corrected. Hyphenation and accent usage have been made consistent. Page 180 had the word 'excusive'. This may be a typographic error for either exclusive or excursive. In the context, exclusive seemed more appropriate, and has been used--"Unless there were a traitor in very exclusive and carefully guarded councils, ..." A table of contents has been added for the convenience of the reader.
