Pharmacologia anti-empirica: or A rational discourse of remedies both chymical and Galenical. Wherein chymistry is impartially represented, the goodness of natural remedies vindicated, and the most celebrated preparations of art proved uncapable of curing diseases without judicious and methodical administration. Together with some remarks on the causes and cure of the gout, the universal use of the Cortex, or Jesuits powder, and the most notorious impostures of divers empiricks and mountebanks. By Walter Harris, M.D. physician in ordinary to His Majesty, and fellow of the Colledge of Physicians.
