Note when as you take your siluer as much as you meane to burne, remember to waie againste it six times as much yealow oaker as it waieth, and seauen times as much of the old earth, that hath been scra∣ped of the annealed worke, as your siluer waieth: which after it is well ground, put altogether into a pot and stir it well, and so vse it, this is the best yea∣low.

Hauing thus (friendly reader) for thy behoof plaid both the Painter and Glasier at once, I craue pardon if in so deepe a skill I haue not satisfied thee in all things: what I haue omitted it is not through Igno∣rance, but because I would not trouble thee a learner (as I imagine) with ouer busie or tedi∣ous conclusions; hauing long since lerned that lesson of Horace. Quicquid praecipies breuis esto. &c. And thus not doubting of thy good will for my paines, such as they are, I throw away my Apron, and bid thee heartily adew.
