A discourse of divers petitions of high concernment, and great consequence; [electronic resource] : delivered by the authour, into the hands of King James, of famous memory, and into the hands of our gracious King Charles; and divers other letters delivered unto some great peers of the land, and divers knights and ladies, and others of great worth and quality. A treatise of melancholie, and the strange effects thereof; with some directions for the comforting of poor afflicted soules, and wounded consciences; and some directions for the curing and reclaiming furious mad men, and some rare inventions, in case of great extremity, to feed them, and preserve them from famishing, and to procure them to speak: which it pleased the God of wisdom to enable me to finde out in the long time of fifty years experience and observation. By John Spencer Gentleman.
