Corpore $mifccri fimul incepere viciflim;
Jamque calent adeo vehementer , ut excita flamma
Protinus exfurgat; tanta eft vis ifta liquorum,
Tam ferus incurlus violentufque. Ob rationem
Hanc itidem,nitri compoftus fpiritus ille
Non abit in flammas confpcrlb flore lyrei?
Non tonat extemplo, non fulmina jaftat in auras
Horribili crepitu cumnitro fulphur & illo

Sulphur enim innitrum, nitrumque in fulphur, inacrem
Immittens fc utrumque falem quoque , fal in utrumque,
Impete prxcipici fic impelluntur, ut una
Protinus omnia eant in flammas, inque vapores,

Protinus atqOc abeant refoluta efflataque in auras ♦
