Public domain
A 1783 Leipzig reprint of Heinrich Khunrath's treatise on the philosophical athanor (alchemical furnace), reissued 'on account of its extreme rarity' after the third edition of 1615 (Magdeburg), with a historical preface listing all of Khunrath's writings. The reprint itself preserves a text the editor described as exceedingly scarce.
