P ra &*A vkich, as to fame of thofe defigned experiments, have been tong denied 
me. Bus having at length got hither one of my little Engines, and having dfo 
procured after much enquiry, a few {mail pieces of Shining Wood, I began on 
the day abovementioned to try with them an Experiment, I found in my Lift. 
And^t hough- the main Experiment be but one • Untended to jet doVen what oc~ 
cure d to me about it but as fever al Phenomena of it -jet finding it requifite, to 
acquaint you withfome Trials , that are not fo properly Parts of it, I fall for dh 
fiinblionfake, propofe them as fever all Experiments • the Narratives whereof 
are taken, for the mofl part , verbatim out of the Notes I fet- down for my own ufe,. 
when the things to be regifired were frefhly done, which advertifement I give 
you, hot to to excufe the carelsfnefs of the Style, and to induce you not to difirusl 
4 Narrative 3 that was made only to ferve my ALemorj, not an Hypothefis,, 
Experiment I. 
T O; try, Whether or no a piece of Shining Wood, being put 
into a Receiver of our Rneujnatick Engtn, would, upon the 
withdrawing and re- admitting of the Air , iuffer fuch changes, 
as 1 have often obferved a Live Ceal, placed there, to doe 5 ha- 
ving at length procured a piece of fuch Wood,, about the bignefi 
©f a Groat orlefs, that gave a vivid light (for rotten Weed) we 
put it into a middle-fized Receiver , fo as it was kept from touch- 
ing the Cement 5 and the Pump being fet a work, we obferved 
nor,, du ing the five or fix firft Exfu&ionsof the Air, that the 
fplendour of the included Wood was manifeftly leifened (though 
it never was at all kicreafed * ) but about the feventb fuck, it 
ieemed to grow a little more dim, and afterwards anfwered our 
expe&atioo, by lofing of its Light more and more, as the Air 
was 01 further pumped out 5 till at length about the tenth Ex- 
fusion ( though by the removal of the Candles out of the room, 
and by black Cioaths and Hats we made the place as dark as we 
could, yet) we could not perceive any Light at ail to proceed 
from the Wood,. 
Experiment II, 
W Herefore we let in the outward Air by degrees., -and had 
the pleafure to fee the feemingly extinguifht Light re- 
vive,, fo fall and perfedlly, that it looked to us all, alraoft like a
