A letter sent to Mr. Henry Stubbe, wherein the Galenical method & medicaments, as likewise bloud-letting in particular, are offered to be proved ineffectual, or destructive, to mankinde; by experimental demonstrations. Also, his answer thereunto by letter; on which animadversions are made by Geo. Thomson, Dr. of physick, by whom is added a vindication of his stomach-essence, or alexi-stomachon, and other really-powerful remedies, from the malicious slanders and active ignorance of the Galenists.
