12. To try, whether I could obtain any juice or moili 
fubftance from this, as 1 have feveral times done from die 
tailsof Gloworms^ I rub'd fome of the fofcer and more 
lacid parts, (which I caufed to be purpofely cut off^) as 
dextroufly as I could, upon my hand, but I did not at all 
perceive any luminous moifture was thereby imparted 
though theflefti feemed by that operation to have loft fome 
of its light. 
15. 1 caufed alfo a piece of ftiining flefh to be compref^ 
fed betwixt two pieces of glafs. to try. how well the con- 
texture of it would refift that external force $ but I did 
not find the light to be thereby extinguiflied during the 
ihort time I could allot to the Experiment* 
14. But (uppofing, that high reftified Spirit of wine 
might fo alter the contexture of the body it permeated, as 
to deftroy its faculty of Shining, I put a luminous piece of 
Veal into a Cryftalline phial,and pouring on it a little pure 
Spirit of wine that would have burned all away, after I 
had (haken them together,! laid by the glafs, and in about 
a quarter of an hour or lefs I found that the light was ya- 
nifhed. 
15. But water would notfo eafily quench our feeming 
fir^s 5 for having put one of them into a Ckina Cup^ and 
almoft filled it with cold water, the light did not only ap-

by being looked upon at no great diftance from a burning 
Candle^ that was none of the fmalleft and probably the 
light would have been feen much longer, if we could have 
afforded to watch out its duration* 
1 6* Whilft thefe things were doing, I caufed the Pneu- 
mattcal Engine to be prepared in a room without fire5(that 
the Experiment might be trycd in a greater degree of 
darknefs 5 ) and having conveyed one of the largeft lumi-
