IV. Zymologia Cbymica , or a Philofiphial Difcourje of Fer- 
mentation , from A Neve Hypothefis of Aciduni and Sulphur • 
With an additioml Difcourfe of the Sulphur-Bath at Knarf- 
brough ; By W. Sympfon M. /), London, i in 
nPHe Learned Author^ not being fatisfied with any thing he 
had yet feenextanc upon this argument of Fermentation^ 
propounds in this Tradt a Hypothecs ^ as an ijf/^^ towards 
the further improvement of that noble Dodrine; endeavouring 
tofolve, from the inward conflifts of /^cidum and Su/phur^ tht 
phaenomenaof d\\ Hot-Baths^ the generation of Minerals^ the 
produ6ion of Spm-vpaters ^ the grand appearances of 
Heat, Fire znd Light ; as alfo various other Subterraneal phae^* 
nomena, Dawps, Earthquakes^ Eruptions; I ike wife the ap- 
pearances of Meteors , and divers other both remarkable and 
entertaining efFefis, 
In the doing of this he firfl explains what he means by ivr- 
mentation ; and fmndly fets forth the large extent thereof in the 
v^^hole orb of Nature, 
He defines to be nothing elfe but an inteftine 
Collifion betwixt Jcidumaud Sulphur^ put together by Nature 
or Art, and fee into a combating motion, in order to the pro- 
duftionof Concrets, or to fome other equivalent end^. 
This definition he applies firji lo the produftions in the 
iW/^fr^/ kingdom , undertaking to folve from thofe two Prin- 
ciples the phsnomeoa of Hot-haths , and the produftion of 
^Minerals , and other fubterraneal appearances. Where he 
laies down two pofitions^ whereof one is, that there is no Hot- 
hath without Sulphur ; the other, that an Acid is neceflTarily re- 
quifite in all M/;^^r^/ fermentations : Declaring withal , what 
he means by Sulphur^ and how Hot-baths differ chiefly according 
to the difference of their Sulphurs ; and w^hich of them are 
fafely, ornot fafely to be taken inveardlyr Endeavouring alfo 
to fliew, how from the principles fpecified, put into fermen- 
tation , the waters paffing through them muft neceffarily be- 
come hot ; confirming this by an induftion of Experiments , 
fliewing, how Sulphur by Fermentation becomes to be commi- 
nuted,
