quickly a Coal would be excinguiflit upon thewith-drawing the 
Air from about it : And as to Shining Wood , the Expeiimeats I 
lately fent you 5 mike it needlefs for me to add any other proof 
of the requifitenefs not only of Air , but of Air of fuch a thick- 
nefSg to make its light continue. How far this isappHable to 
Flame^ it Is not necc&ry here to determine though,when I have 
the fatisfadiiari of feeing you again , I may tell you fomethiog a- 
bout that ^tUim , which perhaps you do not expect, 
3. Both Shining Wood md 4 Burning Coal , hxving hen de- 
prived for a time of their light , the tvith-drawing of the cm- 
tigmm Air 5 ma'] prefentlj recover it h) letting in frejh Air upo» 
them. 
The formr part of this , particular Tryals have often lliown 
you to be true, when kindled Coals, that feem to beextin- 
guiflit in our exhaufted Receivers , were prefcntly revived 5 when 
the Air was reftored to them : And the latter part is abundant- 
ly manifeft by the Experiments , to which this Paper is an Jp- 
fendance,

hyW^ter and many other liquors. 
The truth of this, as to Coals , is too obvious to need a proofs 
and therefore I (hall confirm it only as to JV^od, For which pur- 
pofe you may be pleasM to take the following Tranfcript of 
fome of my iVi/^i about Light, 
I took a piece o{ Shining W&od^md having wetted it with a little 
Common Water ina clear Glafs, 
it prefently loft all its light * From hence you will eafily ga her 
The like Fxoenment 1 fried the reafon, why, when I lately told you of

With ftrong Spirtt of Salt , and ning Fijh under Water in the un-ex-

And leaft you fhould think , that in the Words , Many $thef 
liqt$ors > I intended not to comprife any , that confift of foft 
and unduous parts , or thuare highly inflimable, I (hall fub-
