Excerpt from Elements of Logic: Comprising the Substance of the Article in the Encyclopaedia Metropolitana; With Additions, &C The present edition has been revised with the utmost care. But though the work has undergone not only the close examination of myself and several friends, but the severer scrutiny of determined opponents, I am happy to find that no material errors have been detected, nor an considerable alterations found necessary. Some sm additions have, however, been introduced into the third and fourth editions; and also a change in the arrange ment, which I trust will somewhat lighten the student's labor. I have removed into an Appendix a considerable portion of what was in the first two editions placed in Part I. Tow Chap. I.) of the Compendium; as being (though big ly important, not only from its connexion with the rea soning process, but for other purposes, yet) not necessary, after the perusal of the Analytical Outline, for the under standing of the Second and Third Chapters. It may be studied, at the learner's choice, either before or after the Compendium. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
