At a recent dinner held by members of the courses Government 4 and Government 23, course in international law, G. G. Wilson, professor of international law, spoke on "The Olivart Collection of International Law." This splendid collection of books has been recently purchased and now forms a part of the Harvard Law Library in Langdell Hall. It is considered the most valuable collection of its kind in the world and contains a number of rare and limited editions. It was gathered together by the Marquis de Olivart, a Spanish writer on international law, who is the vice-president of the Institute of International Law and was formerly a professor at the University of Madrid.
