Acknowledgment and thanks are also due to Professor Westel Woodbury Willoughby of Johns Hopkins, who has been so good as to read the translation through in galley proof and give the translator the benefit of his technical knowledge of law; to his Johns Hopkins colleague, Professor Wilfred P. Mustard, who has helped him out of a number of difficulties; to Bishop Shahan, Rector of the Catholic University of America, who has given of his time to help expand several of Grotius’ abbreviated references to theological or canonical authors; to John Curlett Martin, Johns Hopkins Fellow in Greek, who has been of great assistance in the verification of references; and to the men of the Quinn and Boden Company for their courteous assistance while the book was going through the press. _List of Abbreviations_ Auth., Authenticum. Clem., Constitutiones Clementis Papae Quinti. Dist., Distinctio Decreti Gratiani. Extravag., Constitutiones XXD. Ioannis Papae XXII. Lib. VI, Liber sextus Decretalium D. Bonifacii Papae VIII. Other abbreviations should offer no difficulties. _Notes of Explanation_ The words and phrases in the Latin text in capitals follow the type of the Elzevir text. In order that both text and translation may be complete in themselves, the notes below the translation follow the notes of the text in shortened or expanded form, or in duplicate, as the occasion would seem to demand. The notes in Grotius’ Latin text are in a most abbreviated form, and the references are seldom specific. They have been expanded without further explanation.
