Radcliffe College for its assistance in the preparation and publication of this volume. Very especially has he to thank two members of this Bureau, George Grafton Wilson, Professor of International Law at Harvard University, and Manley O. Hudson, Bemis Professor of International Law at the Harvard Law School, for their helpful advice throughout. These gentlemen were good enough to read the manuscript and to offer many valuable recommendations for improvement.
The author is indebted to his wife for her assistance in examining and transcribing many of the old records in this country and abroad and in the preparation of the manuscript, and for her aid and coöperation in many other ways.
The Introduction is taken largely from a paper read by the author before the Grotius Society in London in May, 1927;1 while some of the views expressed in the Conclusions are taken from a paper read before that Society in June, 1928.2
