quisition of Langucdoc. In the Florentine archives I owe much to Francis Philip Nast, Esq., to Professor Felice Tocco, and to Doctor Giuseppe Papaleoni; in those of Naples, to the Superintendent Cav. Minieri Riccio and to the Cav. Leopoldo Ovary; in those of Venice to the Cav. Teodoro Todorini and Sig. Bartolomeo Cecchetti; in those of Brussels to M. Charles Rahlenbeck. In Paris I have to congratulate myself on the careful assiduity with which M. L. Sandret has exhausted for my benefit the rich collections of MSS., especially those of the Bibliothèque Nationale. To a student, separated by a thousand leagues of ocean from the repositories of the Old World, assistance of this nature is a necessity, and I esteem myself fortunate in having enlisted the co-operation of those who have removed for me some of the disabilities of time and space.
Should the remaining portion of my task be hereafter accomplished, I hope to have the opportunity of acknowledging my obligations to many other gentlemen of both hemispheres who have furnished me with unpublished material illustrating the later development of the Holy Office.
Philadelphia, August, 1887
