A brief examination and censure of several medicines, of late years extol’d for universal remedies, and arcana’s of the highest preparation; being indeed some of the trivial toyes, by mistake cryed up for what they are not, others dangerous virulent venoms falsely commended for rare wonder-working mysteries; namely, Lockyers pill, Hughes pouder, Constantines spirit of salt, with several other of that kind, by which the art of pyrotechny is in danger of being brought into reproach and contempt. From the injury of which the pretenders true chymistry is vindicated, and the disguise pluckt off from counterfeit artists, who are discovered to be a pack of ignorant sciolists, an vain-glorious boasters of what they know not, nor can perform. By George Starkey, who is a philosopher by the fire.
