but I found that a much more fimple appara- 
tus was fufiicienr, than the pompous Machine he 
made ufe of. I took a ftrong wide-mouthed Glafs 
Jar, which ferves as a Stand for the Concave Glafs 
Difh to reft on. In the Middle of the Glafs Difh 
is a Hole communicating with a Pipe, which goes 
down into the above-mentioned Jar. Inftead of the 
Golden Bafons, a China Cup a little warmed, ferves 
perfectly as well for burning off the Phofphorus : 
The laft and main thing is a large Glafs Bell, which 
fits nearly clofe upon the Glafs Difh. This Bell 
may be eafily lifted off and on with the Hands by 
an Affiftant, without any Frame or Ropes to fufpend 
it. y 
I took one Ounce of Phofphorus^ which I defla- 
grated in the fame manner as is deferibed in Dr. 
Frohenius\ Experiment, and obtained of the white 
fublimed Flowers ten Drachms, that is two Drachms 
more than the Weight of the Phofphorus before De- 
flagration : They were fat very light as to their Vo- 
lumen, that they juft filled an half Pint Pot. 
The ten Drachms of Flowers being fet in a cooL 
moift Place, expofed to the Air, did relolve into a 
Liquamen , weighing four Ounces and two Drachms, 
which Liquamen much refembles 01 . Sulph. per 
Campanam * but contains an acid Salt* more fix'd in 
the Fire than any other Salt we know of in Nature, 
and having many other Properties peculiar to itfelf, 
which other acid Saits have not. 
The Phofphorus receives this fix’d Acid from the 
Urine only $ for the Salt of Urine is fo fix’d, 
that upon a live Charcoal with a blowing Pipe it 
plays and rolls about like Silver upon the Cupel.
