To 2 or 3 fmall pieces of Phofphorus in a Glafs Difli was 
added a fmall Portion of Oyl of Vitriol, Tartar per Del/qui- 
um, and Oyl ot Cloves, which Mixture fir'd the ?hofphoruf 
in the open Air : But adding a little common Water, the 
Flame extinguifh'dv This Preparation being included in a 
Receiver, very little light appeared : But upon trxbaufting 
the Air, it became very apparent, and fent forth Vivid 
Steams. The Ingredients in the Difh ( at the fame time ) 
appear d very much to refemble a Boyling Flame, exhibit- 
ing a large Light 5 Co that feveral Objefts near it were 
rendered diftinguiftiable, and continud fo till the Air vvh 
admitted, at which time it became Opake. Nor woiii.: 
(liaking the Engine (by which means the Mixture in the 
Difh was put in motion ) produce any fenfible Recovery 
of Light. ' ,

A fmall quantity of the pre-rhention'd Ingredients being 
put into a Bottle with a narrow neck, and included under 
a Receiver, appeared then with very little Light ^ But on 
withdrawing the Air the Fhoffhotus began to be Lu- 
minous, and continued to increate, in proportion to the 
Rarification of the Air, iffuing out of the Bottle in a Ry- 
ramidical form. At laft ( notwithftanding the Receiver 
was well exhaufted ) the Vivid Steams that were then 
emitted were fo fine and (ubtile as to afcend in fo thin 
a medium, reaching the upper parts of the Receiver 
(which was not tall) defcending again by the fides there- 
of. Upon letting in tiie Air the Light perfectly vanifh'd^ 
and it would have been in vain ( as I have often try'd ) 
to have waited in expectation ot its Recovery in the open 
Air.
