After 1516 we find no further mention of Mylner. He was then only about thirty-five years old and may possibly have moved elsewhere; but no trace of him is found. From this time onwards to 1533 almost the whole York book-trade was in the hands of John Gachet, a stationer from France. Gachet’s name is first found in 1509, when, in partnership with another stationer, Jacques Ferrebouc, he commissioned Wynkyn de Worde to print for him an edition of the York _Manual_. This _Manual_ is a very curious book. The colophon states clearly that it was printed in London by Wynkyn de Worde dwelling in the street called Fleet Street at the sign of the Sun, or in St Paul’s Churchyard under the image of Our Lady of Pity, for John Gachet and James Ferrebouc, partners. In spite of this assertion it is plain that the book was printed abroad. The paper, the type of the text and music staves, the illustrations, all are obviously foreign, and the particular device of De Worde on the title-page is only found in books printed for him in Paris. The colophon unfortunately does not state where Gachet and Ferrebouc were living, but the latter was certainly just before and after 1509 in Paris. Perhaps Gachet may have been the travelling member of the firm and have journeyed as far as York on his business tours. By 1514 he was certainly settled there, for in that year he was admitted a brother of the Corpus Christi Guild. In 1516 and 1517 he published a series of service books, a _Missal_, a _Processional_, a _Manual_, a _Hymnal_, and a _Book of Hours_. The _Missal_ is a fine folio of 200 leaves, and there is a perfect copy with two leaves printed on vellum, which formerly belonged to Bishop Moore, in the University Library. Another copy, slightly imperfect, was given to Pembroke College Library by the Master, Bishop Launcelot Andrews, in 1589. Besides these, five other copies are known. The initial M of the word Missale on the title-page is a very large and elaborate letter, having a scroll up the centre limb on which is engraved the printer’s name M. P. Holivier. Similar ornamental letters containing their names were used by other Rouen printers, such as Morin. The _Processional_ is without date, and the colophon states that it was printed at Rouen by Olivier for John Gachet, alias de France. A copy of this edition is at Ripon, and there are perhaps others; but both Dr Henderson, in his list of York service books, and Davies have mixed up this edition with the later dated edition of 1530.
