(C by flames : All flaming bodies, as Oil, 

 « Tallow, Wax, Wood, foffil Coals, Pitch, 

 <c Sulphur, by flaming wafte and vanifh into 

 u burning fmoak ; which fmoak, if the flame 

 < c be put out, is very thick and vifible, and 

 c< fometimes fmells ftrongly, but in flame 

 " lofes its fmell by burning ; and according 

 <c to the nature of the fmoak the flame is 



of feveral colours, as that of fulphur, blue ; 



that of copper opened with fublimate, 



green; that of tallow, yellow; that of

 <c than that of flame." 



But Mr. Lemery the younger fays, cc That 

 " the matter of light produces fulphur, be- 

 cc ing mixt with compofitions of fait, earth, 

 " and water, and that all inflammable mat- 

 « c ters are fuch only in virtue of the parti- 

 <c cles of fire which they contain. For in 

 " the Analyfis, fuch inflammable bodies pro- 

 " duce fait, earth, water, and a certain fubtle 

 " matter, which paries through the clofeft 

 " veflfels ; fo that what pains foever the artift 

 " ufes, not to lofe any thing, he ftill finds a 

 €C confiderable diminution of weight.
