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. IT is twenty-four years since this work was first published, and during the first fifteen of that period it passed through three large editions. The fourth appeared nine years ago, and that has long since been out of print. I have now finished the Fifth Edition, in which will be found a great deal of new matter, enlarging the work to upwards of 150 pages more than there were in the last.
