PREFACE.

THE following Essay was originally published under the title of "A Compend of Lectures on the Aims and Duties of the Profession of the Law, delivered before the Law Class of the University of Pennsylvania." A portion of it had been read by the author as an Introductory Lecture at the opening of the Fifth Session of the Law Department of that Institution, October 2d, 1854. The young gentlemen, alumni, and students of the school, who were present on that occasion, requested a copy for publication, in order that each of them might possess a memento of their connection with the Institution. The author preferred to publish the entire Compend than merely a part of it. He hesitated much in doing so, because the questions discussed are difficult, and opinions upon them variant, and he could scarcely hope that he had in every case succeeded in just discrimination. A review of the matter

now, when a second edition has been called for, has suggested, however, no important change in the principles advanced, though a few additions have been made, some inaccuracies corrected, and an introduction upon the importance of the profession, in a public point of view, prefixed.
