Concerning the material here collected, the two military articles first appeared in the “Harvard Graduates’ Magazine.” Of the legal articles, the sketch of Professor Langdell was written for the “‘Green Bag”: and the history of the Law School has been elaborated from a paper read before the Choate Club of the School, and subsequently published in the “Atlantic Monthly.” The medical paper, an extract from an extended essay on the medical conditions of 1775, was read before the Harvard Medical Society and afterwards printed in the “Harvard Alumni Bulletin.” The architectural paper (first read before the Harvard Memorial Society), and the remaining articles in this volume, likewise appeared in the “Bulletin.” Acknowledgments are due the editors of the above publications for courteous permission to reprint.
