In Bertrand's _Lettre Missive_, we follow the original Paris edition, in Lenox. It is a rare publication, the Lenox copy being apparently the only one in the United States; Brown has a manuscript copy, made from that at Lenox. Sabin (vol. x., no. 40682), says: "It is a piece of unusual rarity." Sabin has a previous reference in vol. ii., no. 5025, under caption "Bertrand," wherein a misprint makes him cite the date of the letter as "28 June, 1618" (eight years later than the actual date); a further misprint causes Sabin to record the pamphlet as having "48 pages or less," the actual number being 8. In his _Notes_, Harrisse omits a line-ending after the second "nouuelle" in his description of the title-page. See, for further references: Ternaux, no. 329; Winsor, p. 299; Lenox Catalogue, p. 3; Brown Catalogue, vol. ii., no. 103. _Title-page._ Given in photographic facsimile, in present volume. _Collation._ Title, 1 p.; blank at back of title, 1 p.; text, pp. 3-6; dated on p. 6, "Port Royal xxviij. Iuin, 1610," and signed "Bertrand." Blank leaf at end, completing 4 leaves = 8 pp. III-VI In these four letters, by Biard and Massé, we follow Carayon's _Première Mission des Jésuites au Canada_ (Paris, 1864). It is a scarce book, and brought $8 at the Barlow Sale, in New York, 1890. See references in Harrisse, p. 285; Sabin, no. 10792; Winsor, pp. 151, 292, 300; and Lenox Catalogue, p. 15. The origin of the letters in the volume is found at the top of the first page of each letter; and these data, with accompanying notes by Carayon, are reproduced in the present series, which will, in strict chronological order, contain all of the papers given by that editor; although in many cases we shall follow the original issues of the letters, whenever found. Documents III., V., and VI. were written in Latin; and Document IV. in French. _Collation._ Blank, 2 pp.; bastard title, 1 p.; blank, 1 p.; title proper, 1 p.; blank, 1 p. Preface begins on p. vii. (not numbered), and ends on p. xvi. Preface acknowledges indebtedness to F. Felix Martin, S. J., for copying and translating into French (from the Latin) most of the letters in the volume. Text, pp. 1-302; Table at end, 2 pp.; the last of these is numbered 304. VII We follow the style and make-up of Dr. E. B. O'Callaghan's Reprint (Albany, N. Y., 1871) of the _Canadicæ Missionis_, in Jouvency's _Hist. Soc. Jesu_, part v., commencing p. 321. In the Lenox Catalogue, it is designated "O'Callaghan's Reprint, No. 4." This numbering of O'Callaghan's reprints, is merely a device peculiar to the Lenox Catalogue, for sake of easy reference, and has been followed by Winsor; the reprints themselves bear no numbers.
