Translator’s Note

The present volume has been translated, with the author’s consent, from the French of the Marquis de Nadaillac. The author and translator have carefully brought down to date the original edition, embodying the discoveries made during the progress of the work. The book will be found to be an epitome of all that is known on the subject of which it treats, and covers ground not at present occupied by any other work in the English language.
