A typewritten transcript, annotated by hand, of the Cornell manuscript of the unprinted portions of Castellion's Defensio suarum translationum Bibliorum. The transcript was made by American historian Roland H. Bainton and was collated with a similar manuscript in the British Museum. Both of these manuscripts were appended to copies of the printed Defensio. With the transcript is a cover letter from Bainton to George Lincoln Burr, with an explanatory note later added by Burr.
