"I shall now describe the Garbha Yantram for reducing *pistikā*¹ to ashes. Make a crucible 4 digits in length, and 3 digits in width, with its mouth rounded. Take 20 parts of salt and one of bdellium and pound them finely, adding water frequently; rub the crucible with this mixture. * * * Make a fire of paddy husks and apply gentle heat. In the course of one to three days the mercury is reduced to ashes." [*Vide* Illustrations.]
