considerably from that in the Scots "Detection." Research has revealed the existence of English translations of Nos. I. and II. and French versions of Nos. III. and V. in the Record Office; and of English translations and French versions of Nos. IV. and VI. at Hatfield. All these various versions will be found printed, in careful and scholarly fashion, in Appendix C. of Mr. T. F. Henderson's "Casket Letters and Mary Queen of Scots." The method adopted in the present work has been to print the Scots version of all the letters, with a glossary of unusual words. It is the only complete version, and the published French and Latin letters are probably derived from it. Variations both in these and in such English and French versions of the letters as are at Hatfield or the Record Office, are indicated in notes appended to each letter. Care should be taken to distinguish between these Hatfield or Record Office French versions and the "Published French," _i.e._ the French of the edition of 1573. References to the literature of the question will be found in an Appendix. For the guidance of the reader, it may be added that one section of the discussion turns upon the question whether French originals of Nos. I., II., VII., and VIII. ever existed; and the Scots and English have been carefully examined to discover if they bear traces of derivation from a French source. Of the other contents of the Casket, the Sonnets, and the important clauses of the marriage contracts will be found immediately after the letters.] The following Scots words, which appear frequently in the text of the letters, may be unknown to English readers:--
