Zymologia physica, or a brief philosophical discourse of fermentation, from a new hypothesis of acidum and sulphur. Whereby the phoenomena of all natural hot-baths, the generation of minerals, the production of many acidulæ or spaw-waters, the grand apparances [sic] of hea fire, and light, throughout the triplicity of natures dominions, in the productions of bodies, are solv’d from the intestine duellings and inward collisions of the foresaid principles. Whereby also various other subterraneal phoenomena, as damps, earth-quakes, eruptions, &c. likewise the apparance [sic] of meteors, &c. and divers other no less remarkable then entertaining, are from the same doctrine of fermentation genuinely solv’d. With an additional discourse of the sulfur-bath at Knarsbrough. By W. Simpson, M.D.
