WILLIAM GILBERT [Illustration] PRIVATELY PRINTED LONDON MCMI "For out of olde feldes, as men seith, Cometh al this newe corn fro yeer to yere; And out of olde bokes, in good feith, Cometh al this newe science that men lere." --_Chaucer._ "I finde that you have vsed in this your tr[=a]slation greate art, knowledge, and discretion. For walking as it were in golden fetters (as al Translators doe) you notwithstanding so warilie follow your Auctor, that where he trippeth you hold him vp, and where he goeth out of the way, you better direct his foote. You haue not only with the Bee sucked out the best iuyce from so sweete a flower, but with the Silke-worme as it were wouen out of your owne bowels, the finest silke; & that which is more, not rude & raw silke, but finely died with the fresh colour of your owne Art, Invention, and Practise. If these Adamantes draw you not to effect this which you haue so happilie begunne: then let these spurres driue you forward: viz. Your owne promise, the expectation of your friends, the losse of some credit if you should steppe backe, the profit which your labours may yeeld to many, the earnest desire which you yourselfe haue to reviue this Arte, and the vndoubted acceptation of your paines, if you performe the same."--(Prefatory epistle of John Case, D. of Physicke, printed in R. Haydocke's translation of _The Artes of Curious Painting_, of Lomatius, Oxford, 1598.) "This booke is not for every rude and unconnynge man to see, but for clerkys and very gentylmen that understand gentylness and scyence."--_Caxton._ CHISWICK PRESS: CHARLES WHITTINGHAM AND CO.
