For thei be whom this art was founde To every point a certain bounde Ordeignen, that a man mai finde This craft is wroght be weie of kinde, So that ther is no fallas inne. Bot what man that this werk beginne, 2510 He mot awaite at every tyde, So that nothing be left aside, Ferst of the distillacion, Forth with the congelacion, Solucion, descencion, And kepe in his entencion The point of sublimacion, And forth with calcinacion Of veray approbacion Do that ther be fixacion 2520 With tempred hetes of the fyr, Til he the parfit Elixir Of thilke philosophres Ston Mai gete, of which that many on Of Philosophres whilom write. And if thou wolt the names wite Of thilke Ston with othre tuo, Whiche as the clerkes maden tho, So as the bokes it recorden, The kinde of hem I schal recorden. 2530 These olde Philosophres wyse Be weie of kinde in sondri wise Thre Stones maden thurgh clergie.
