H. Gerritsz seized the opportunity, occasioned by the interest in Hudson’s voyage and his fate, to promulgate his views of the greater chance of finding a northwest passage to India, rather than a northeast one; and in the little collection of tracts edited by him, produced first in the Dutch edition of 1612, he gives but a very brief narrative of Hudson’s voyage, which is printed on the reverse of the map showing his discoveries,—the maps, which he gives, both of the world and of the north parts of America being the chief arguments of his book, the latter map being also reproduced by Asher. The original Dutch edition is extremely scarce, but four or five copies being known. A reproduction of it in 1878 by Kroon, through the photo-lithographic process, consists of 200 copies, and contains also, under the general title of _Detectio freti Hudsoni_, a reproduction of the Latin edition of 1613, with an English version by F. J. Millard, and an Introductory Essay on the origin and design of this collection, which, besides Gerritsz’s tract, includes others by Massa and De Quir. Sabin’s _Dictionary_, viii. 33,489; Asher’s _Hudson_, p. 267. In the enlarged Latin translation, ordinarily quoted as the _Detectio freti Hudsoni_ of 1612, Gerritsz inverted the order of the several tracts, giving more prominence to Hudson, as May’s expedition to the northeast had in the mean time returned unsuccessful. _Huth Catalogue_, ii. 744, shows better than _Brunet_, iii. 358, the difference between this 1612 and the 1613 editions. H. C. Murphy’s _Henry Hudson in Holland_. The _Carter-Brown Catalogue_, ii. 131, gives this little quarto the following title: _Descriptio ac delineatio Geographica detectionis freti sive, Transitus ad Occasum, suprà terras Americanas in Chinam atq: Iaponem ducturi, Recens investigati ab M. Henrico Hudsono Anglo_, etc., and cites the world in two hemispheres as among the three maps which it contains. A copy in Mr. Henry C. Murphy’s collection has a second title, which shows that Vitellus and not Gerritsz made the Latin translation. This other title reads: _Exemplar Libelli ... super Detectione quintæ Orbis terrarum partiscui Australiæ Incognitæ nomen est: item Relatio super Freto per M. Hudsonum Anglum quæsito, ac in parte dedecte supra Provincias Terræ Novæ, novæque Hispaniæ, Chinam, et Cathaiam versus ducturo ... Latine versa ab R. Vitellio, Amstelodami ex officina Hessilii Gerardi. Anno 1612_. Speaking of this little tract and the share which Gerritsz had in it, Asher, in his _Henry Hudson the Navigator_, says, “Around it grew in a very remarkable manner the most interesting of the many collections of voyages and travels printed in the early part of the sixteenth century.”
