4407 SIMPSON [or SYMPSON] (William, MD.) Zymologia Physica, or a brief PHILOSOPHICAL 

 Discourse of Fermentation, from a New Hypothesis of Acidum and Sulphur, wheiebj the 

 Phuinomenaof all natural Hot-Baths, the Generation of Minerals, the Production of many Acidulaj 

 or Si)aw- waters, the Grand apparances of Heat, Fire, and Light, throughout the triplicity of 

 Nature's Dominions, in the productions of Bodies, are solv'd from the INTE.STINE duellings and 

 inward collisions of the foresaid principles. Whereby other subterraneal Phoenomena, as 

 Damps, Earth-c^uakes, Eruptions, etc. likewise the appearances of Meteors, etc. . . . are from" 

 the same Doctrine of Fermentation genuinely solv'd ; with a Discourse of the Sulphur-Bath at 

 Knarsbrough, 12mo. contemporary sheep {some slight wormholeSy but a sound copy) ; very 

 rare, £2. 2s W. Cooper, 1675 



The author develops a theory of ' fermentation ' to explain physiological and chemical phenomena. A passage on p. 2 

 is of interest in connexion with the atomic theory : ' Whereas the Corpuscularians (who are now the most recent Physio- 

 logists) suppose matter under the consideration of motion and figure, to be the competent Elements and Principles of 

 Bodies, we shall shew, that by the power of fermentation, one part of matter mechanically indivisible, may for ought we 

 know be splitt and sub-divided by a subtile comminution into 1000 perhaps lO.CJO parts.' 



'The author seems to have tried the effect of mixing sulphur and nitre, and to have convinced himself that mineral 

 waters, hot springs, volcanoes, earthquakes, St. Elmo's fire, meteors, and even the occasional luminosity of the sea were 

 all due to mixtures of these two bodies with water or vapour.'— G. J. Symont, F.R.S.
