€C and thereby flames : All flaming bodies, 
<c as Oil, Tallow, Wax, Wood, foffii Coals,

“ into burning fmoak ; which fmoak, if the 
“ flame be put out, is very thick and viftble, 
<c and fometimes fmells ftrongly, but in 
* flame lofes its fmell by burning; and ac- 
iC cording to the nature of the fmoak the 
cc flame is of feveral colours, as that of 
iC fulphur, blue ^ that of copper opened with 
<c fublimate, green; that of tallow, yellow 5 
“ that of camphire, white; fmoak palling 
“ thro* flame cannot but grow red hot, and 
u red hot fmoak can have no other appea- 
€C ranee than that of flame/’ 
But Mr. Lemery the younger fays, u that

“ and water, and that all inflammable mat- 
<c ters are fuch only in vertue of the par- 
<c tides of fire which they contain. For in 
tc the Analyfis, fuch inflammable bodies 
<£ produce fait, earth, water, and a certain 
a fubtle matter, which pafies thro" the ciofeft 
“ veflels, fo that what pains foever the ar- 
“ till ufes, not to lofe any thing, he ftill 
“ finds a confiderable diminution of weight.
