dies, and unffcuous Earths, in Pitch, Roiin, Wax

Observations on the Phosphorus.. 
I. From what hath been faid, we fee that ,the 
Saponaceous Magma of Urine has great Affinity 
with common Sulphur ; being a fulphureous Body, 
compofed of an acid and depurated Oil, join’d with 
a fmall Proportion of Earth. 
II. Our Phofphoreal Magma comes very near 
Homberg' s Pyr op horns, which wants only the Salt 
of Urine in it, in the room of which Allum is ufed- 
to fix the Sulphur. 
III. We may obferve hence, that urinous Parti- 
cles exid in greater abundance in Animals ; but the 
Phlogifion abounds molt in Vegetables, from which' 
is prepared that fine JEthereal Spirit ffiewn by Dr, 
Frobenius. 
IV. We produce the Phlogifion out of fat Sub* 
dances, and from the Phlogifion a Fuligo, or Soot, 
and from the Fuligo an urinous Salt. 
V. From the corrofive Oil of Sulphur, we have 
a pure fubtile Oil, which is intimately combined - 
with if, and is the adtual Fire of the Phofphorus, that' 
by barely rubbing, or the lead Degree of Heat, is* 
kindled into Flame.
