The author, in sending out the third edition, begs to call attention to the first sentence in the preface. For while he has nothing to alter in the interests of accuracy, he desires that it should be understood that the friend to whom the letters are addressed is not in any way responsible for the statements made, or for the conclusions drawn.
Thankful for the wide acceptance which has been vouchsafed to his feeble effort to call attention to forgotten truths, the author desires to commend it anew to the blessing of God.
