Experiment I. 
TO try. Whether or no a piece of shining Wood, being put 
into a Receiver o( our F^ematick Engh^wonld, upon the 
vyichdrawing and re-admitcing of the Air, iuffer fuch changes, 
as I have ofcen obferved a Live Coaly placed there, to doe 5 ha- 
ving St length procured a piece of fuch Wood, about the bignefs 
of a Gmt oriefSj that gave a vivid light (for rot ten Woo ii) we 
pm it into a middle-fized Receiver, fo as it was kept from touch- 
ing the Cement and the Pump being fet a work, wc obferved 
nor, du ing the^k^^ory^xfirft Exfuftionsof the Air, that the 
fpleadouroftheincludcd Wood was manifeftly leffened (though 
it never was at all iacreafed but abouc the /^i/^i*/^ fuck, it 
feemed to grow a little more dim, and afterwards anfwcred our 
€xpc(aation^ by lofing of its Light more and more, as the Air 
was ftill further pumped out 5 till at length about thttenth^x- 
fudtion r though by the removal of the Candles out of the rooni, 
and by black Cioaths and Hats W3 made the place as dark as we 
could, yet) we could not perceive any Light at all to proceed 
from the Wood» 
Experiment 11. 
WHcrefore we let in the outward Air by degrees, and had 
the pleafure to fee the fecmingly extinguifhc Light re- 
vive, fo faft and perfeilly, that it looked to us all, almoft like a 
little fUfh of Lightningj aiid the fpkndour of the Wood feemed
