Whilst the greatest effort has been made to ensure the quality of this text, due to the historical nature of this content, in some rare cases there may be minor issues with legibility. The material from which this little work has been drawn has necessarily been exceedingly various. I had at one time thought of indicating the many authorities to whose works I am indebted for information, and as far as possible this has been done in the footnotes to the text. So extensive, however, have been the sources from which my information has been derived, that it will hardly be surprising if some have been left unacknowledged.
