 Art. Pyrophorus. 



The moft eafy procefs for producing Romberg's phofphorus con- 

 lifts in mixing three parts of alum with one of lui^ar, wh.ch are to be 



expofed to a great heat in a covered crucible, till a bluifti flame has 

 appeared for fome time. It muft then be fufFered to cool a little, and 

 be put into a dry hot bottle, and clofely ftopped from the air. A 

 drachm of this powder will afterwards, when poured from the bottle 



into the ooen 



air on paper, quickly kindle, become red like burning 



coals, and burn the paper, which it lies upon. 



Hence we may conclude, that vegetable bodies, as well as animal 



ones.
