The admirable efficacy, and almost incredible virtue of true oyl, which is made of sulphur-vive, set on fire, and called commonly oyl of sulphur per campane. To distinguish it from that rascally sophisticate oyl of sulphur, which instead of this true oyl, is unfaithfully prepared, and sold by druggists and apothecaries, to the dishonour of art, and unspeakable damage of their deluded patients. Faithfully collected out of the writings of the most accute philosopher, and unparaleld doctor of this last age, John Baptist Van Helmont, of a noble extraction in Belgia, and confirmed by the experience of. [sic] George Starkey, who is a philosopher by the fire.
