Thus we fee what a wonderful Subjeft is Phof- 
phorus ! And how furprifing is it that fuch an infla- 
mable Body, confiding of the undious and acid 
Parts of the Urine, fhould thus become Glafs ! 
The Conclufion which I muft now make from this 
remarkable Experiment is, That here is a perfeft 
Tranfmutation of Bodies ; the Phofphorus being 
tranfmuted into a fine tranfparent Glafs of a bluilh 
green Colour, coming nearer to the Hardnefs of a 
Diamond than any other Glafs, and in the fame 
Quantity as the Phofphorus at fird ufed, which, 
without any Addition, produces this Glafs Ounce 
for Ounce. Here I mult flop, having brought thefe 
wonderful Experiments to a ne plus ultra. 
I fhall add here further, that the crude Phofphorus , 
without any Deflagration, but only cut very fmall, 
or fcraped fine with a Knife, and laid upon a Glafs 
Diih in moift Air, will in about a Week’s time re- 
folve into a Liquawen near eight times its original 
Weight : Which Liquamen is the fame in all refpeds 
as that which comes from the fublimed Flowers by 
Deflagration, and may be vitrified likewife. In 
fcraping the Phofphorus , take great Care not to do 
it too haftily, lead by heating it, you fet it on 
fire. 
Reflections on thefe Experiments. 
The Chemical Phofphorus being the principal 
SubjeQ; of the ’foregoing Experiments, I fhall, upon 
this Occafion, givefome Account of what Phofpho - 
rus is, and what it chiefly confids of. It is my Opi- 
nion, that Phofphorus doth not naturally exid
