r-2. To try, whether I could obtain any juice or moift 
fubftance from this, as 1 have feveral times done from the 
tails of Gloworms 3 I rub'd fome of the fofter and more 
lucid parts, (which I caufed to be purpofely cut ofF,) as 
dextroufly as I could, upon my hand, but I did not at at] 
perceive any luminous moifture was thereby imparted j 
though the flefti feemed by that operation to have loft fome 
of its light. 
13. 1 caufed alfo a piece of ftiining flefli to be compreP 
fed betwixt two pieces of glafs^ to try, how well the con- 
texture of it would refift that external force s but I did 
not find the light to be thereby extinguilhed during the 
ihort time I could allot to the Experiment^ 
14. But ^uppofing^> that high reftified Spirit of wine 
might fpaltc^the contexture of the body itpermeatedj as 
to deftroy its faculty of Shining, I put a luminous piece of 
Veal into a Gryftalline phial,aDd pouring on it a little pure 
Spirit of wine that would have burned all away, after I 
had (hakeo them together^I laid by the glafs, and in about 
a quarter of an hour or left I found that the light was var 
Bifhed. 
15. But water would notfo eafily quench our feeming 
fires 5 for having put one of fhem into a China Cup^ and 
altnoft filled it with cold water^ the light did not only ap- 
pear, perhaps undiminifhedj through that Liquor, hut2r 
bove an hour after was vigorous enough not to be eclipfed 
by being looked upon- at no great diftance from a burning 
Gandie^ that was none of the fraalleft 5 and probably the 
light would have been feen much longer, if we could hav© 
afforded to watch out its duration^ 
i6v WHilft thefe things were doing, I caufed' the Pneo'- 
I matical Engine to be prepared in a room without fire3(that 
the Experiment might be trycd in a greater degree of 
darkoefs 5 ) and having conveyed one of the largeft lumi- 
I ^ nous pieces into afmall Receiver, we caufed the candles 
to be put outj , and the pomp to be plied in the dark $ bm
