ADVERTISEMENT TO THE THIRD EDITION. THE author, having had the satisfaction of knowing that some good has been done, both at home and abroad, by the divine blessing upon this quiet little book, is encouraged to send it, after a careful revision, again to the press, as the former editions were exhausted some time since, while the demand still continues. He has chosen for it a form smaller and cheaper, though not less neat, that it may be within the reach of more, yet easily read. The seed is scattered by a feeble hand, but not without hope that the God of the harvest will give it increase to the praise of his holy and merciful name. PHILADELPHIA, |
