Know then friend _Puccio_, the Philosophers do hold, that such as covet to become rich indeed, must understand how to make the Stone: as I will tell thee how, but marke the manner very heedfully. I do not say, that after the Stone is obtained, thou shalt be even as rich as now thou art; but thou shalt plainly perceive, that the very grosest substance, which hitherto thou hast seene, all of them shal be made pure golde, and such as afterward thou makest, shall be more certaine, then to go or come with _Aqua fortis_, as now they do. Most expedient is it therefore, that when a man will go diligently about this businesse, and purposeth to prosecute such a singular labour, which will and must continue for the space of 40 nights, he must give very carefull attendance, wholly abstaining from sleepe, slumbering, or so much as nodding all that while. Moreover, in some apt and convenient place of thy house, there must be a forge or furnace erected, framed in decent and formall fashion, and neere it a large table placed, ordered in such sort, as standing upright on thy feete, and leaning the reines of thy backe against it; thou must stande stedfastly in that manner every night, without the least motion or stirring, untill the breake of day appeareth, and thine eyes still uppon the Furnace fixed, to keepe ever in memory, the true order which I have prescribed. So soone as the morning is seene, thou mayst (if thou wilt) walke, or rest a little upon thy bed, and afterward go about thy businesse, if thou have any. Then go to dinner, attending readily till the evenings approch, preparing such things as I will readily set thee downe in writing, without which there is not any thing to bee done; and then returne to the same taske againe, not varying a jot from the course directed. Before the time be fully expired, thou shalt perceive many apparant signes, that the stone is still in absolute forwardnesse, but it will bee utterly lost if thou fayle in the least of all the observances. And when the experience hath crowned thy labour, thou art sure to have the Philosophers stone, and thereby shalt be able to enrich all, and worke wonders beside.
