fuf preyed by the withdrawing of the Air. Wherefore hiving re- 
moved the Receher into a convenient place, I caufeditto be 
brought CO me about midnight (after I was a bed) and having by 
clofe drawing the Curtains, and other means, made the place 
pretty dark, I perceived the included Body to continue to fliine 
more vividly, than one would have expeSed, (and, if T miftake 
not, I faw it Oiining in the morning, whilft it was dark-,) but the 
night after, coming to look upon it again, its light appeared no 
more : notwithftanding which, I made a fliift to keep out the Air 
^boiK 24 hours longer, and fo after 48 hours in all, we opened 
the Receiver in a dark place, and prefently upon the ingrcfs of 
the Air were pleafingly faluted with fo vivid an Apparition of 
Light, that the included Body continued to (hine, when carried

The fuddennefsj with which the included B)dy appeared to

thefe jhort'liv d apparitions oilA%hi (tQx\ fpeak not now of red 
Lamps, found in Tombs, for a reafon to be told you another 
time,) which difclofing therafelves upon mens comiag in, and 
conftquently letting in frefh Air into Vaults, that had been very 
long clofr, did foon after vaniih. Thefe thoughts, as I was fay-

the fudden operation of the frefti Air upon a Body, that but a 
minute before difclofed no light. For, chough the Lights report-
