Secondly, it is the first book of any size undertaken by Siberch. "Ignosces," he pleads, "candide lector iam primum experienti mihi." Further, the phrase _Cum gratia et privilegio_ is now used on the title-page for the first time; for this leave had probably been obtained through Bishop Fisher, in a dedication to whom the printer calls himself 'Cantabrigiensis typographus.' Four copies are known: two in the British Museum, one in St John's College, Cambridge, and one in Corpus Christi College, Cambridge; the last has an additional interest in that it was bound by Nicholas Speryng. VI The sixth of the books printed by Siberch is the commonest. It is a translation of Galen by Thomas Linacre: _Caleni Pergamensis de Temperamentis, et de inaequali intemperie libri tres Thoma Linacro Anglo interprete._ It is described on the title-page, which has the same border-device as III, as "opus non medicis modo, sed et philosophis oppido q_uam_ necessariu_m_"; it is dedicated to Pope Leo X and printed "cum gratia et privilegio." [Illustration: TITLE-PAGE OF FISHER'S SERMON] The existing copies of the book are in two states: a copy in the first state was found by the late Mr Robert Bowes in the library of Trinity College, Dublin, containing only the _De Temperamentis_ and having on the last leaf but one a woodcut of the Adoration of the Shepherds. The copy in the Royal College of Physicians consists of this first issue with the second essay added. The remaining ten copies--University Library, Cambridge (2); Bodleian Library (2); British Museum; Trinity College, Cambridge; All Souls' College, Oxford; Hunterian Museum, Glasgow; the Duke of Devonshire; Mr Bowes--are in the second state, containing both the _De Temperamentis_ and the _De inaequali intemperie_, the last two leaves of the former essay as they appear in the first state being cancelled. VII The full title of the seventh Cambridge book may be read in the facsimile here shown. It is a Latin translation of the sermon delivered in London by Fisher when Luther's books were publicly burned. Siberch has now discarded his ornamental title-border, but at the end of the book there appears a new device, embodying his trade-mark and initials. The book was printed late in 1521 and probably issued early in the January of the next year. Five copies are known: two in the Bodleian Library; one in the University Library, Cambridge; one in Magdalene College, Cambridge; and one in the John Rylands Library, Manchester. VIII The last of the eight books printed by Siberch of which complete copies survive is _Papyrii Gemini Eleatis Hermathena, seu De Eloquentiae Victoria_, printed on the 8th December, 1522. There are three different states of the title-page and six complete copies are known: University Library, Cambridge; British Museum; St John's College, Oxford; Archbishop Marsh's Library, St Patrick's, Dublin; Duke of Devonshire; Lincoln Cathedral Library.
