Ir was my design, soon after this volume was published, to subject it to a thorough revision, and make such corrections in the text as were evidently needed. I found myself, however, unable at the time to accomplish my intention, in consequence of several other unexpected and imperative obligations; and, subsequently, by reason of a long period of imperfect health. I have devoted to this work the first leisure that I have been able to command; and have corrected the text with all the attention in my power. I hope that I have improved it. In this labor I have been greatly assisted by the aid of another. Some time since, I received from an anonymous friend a copious list of valuable corrections, of which I have freely availed myself. I take this method of expressing my sincere gratitude to my unknown benefactor; and I beg him to receive my thanks for his careful reading of the text, and for his many valuable suggestions. Most of these I have thankfully adopted. PROVIDENCE, R. I., May, 1865. F. WAYLAND. |
