quickly a Goa! would be extinguifk upon the with-drawing the 
Air from about it s And as to Shining Wood , the Experiments I 
lately femt you , make it needlefs for me to add any other proof 
of the requifitenefs not only of Air , but of Air of fuch a thick- 
nefs 3 to make its light continue. How far this is applicable to 
Flame , it is not neceffary here to determine ^ though, when I have 
the fatisfadion of feeing you again , I may tell you fomething a- 
bout that QucJlion , which perhaps you do not exped. 
3. Beth Shining Wood and 4 Burning Coal , having been de- 
prived for a time of their light , by the with-drawing of the con- 
tigitom Air , may prefently recover it by letting in frejh Air upon 
them. 
The former part of this , particular Try als have often {hown 
you to be true, when kindled Coals , that feem to beextin- 
guifht in ourexhaufted Receivers , were prefently reviv'd , when 
the Air was reftored to them s And the latter part is abundant- 
ly manifeft by the Experiments s to which thisHPaper is an Ap - 
pndance . 
4. Both a quick Coal and Shining Wood will be eafily qnencht 
by Water and many other liquors. 
The truth of this, as to Coals , is too obvious to need a proof* 
and therefore I fliall confirm it only as to Wood. For which pur- 
pofe you may be pleis'd to take the following Tranfcript of 
fome of my Notes about Light. 
I took a piece oi Shining wood^ and having wetted it with a little 
Common Water ina clear G ! afs 5 
it prefently loft all its light 
The like Experiment! tried 
with ftrong Spirit of Salt , and 
alfo with weak Spirit of Sal Ar~ 
mniacky but in both the light 
did 3 upon the Woods inbibing of 
the liquor prefently difappear. 
And leaft you fhouid think , that in the Words , Many other 
liquors » I intended not to comprife any , that confift of foft 
and unduous parts j or that are highly infhmable , I fhall fub- 
joyn a couple of Notes > that I find next to thofe juft now tran- 
feribedo

* From hence you will eafily ga her 
the reafon, why, when I lately told you of 
the Trial , I made with a piece of S hi- 
ning Fijb under Water in the un-ex- 
haufted Receiver •» I did not propofe 
to have the like Trial made with Shi- 
ning Wood, and Water j butf©rffe;V Li-
