Note 20 — Chapter I · OF ALCHYMY.
Reading edition
Whoever wishes to enter more particularly into the processes for making the philosopher’s stone contrived by the alchymists, will find a good deal of information on the subject in Stahl’s Fundamenta Chemiæ, vol. i. p. 219, in his chapter De lapide philosophorum: and Junker’s Conspectus Chemiæ, vol. i. p. 604, in his tabula 28, De transmutatione metallorum universali: and tabula 29, De transmutatione metallorum particulari.
