I have found by trial, that, with a 

 greater and competent degree of 

 heat, this Precipitate per fe, would* 

 without the help of any volatilizing 

 additament, be eafily reduced into 

 running Mercury again. Chymifts 

 and Phyficians, who agree in fuppo- 

 (idg this Precipitate to be made with- 

 out any additament, will perchance 

 fcarce be able to give a more likely 

 account of the confiftency and de- 

 gree of Fixity that is obtained in 

 the Mercury 5 in which, fince nobo- 

 dy is added to it, there appears not 

 to be wrought any but & Mechanical 

 change. And though, I confefs, I 

 have not been without fufpicions, 

 that in Philofbphical ftri&nefs this 

 Precipitate may not be made perfe^ 

 but that fome penetrating igneous 

 particles, efpecially faline, may have 

 affociated themfelves with the Mer- 

 curial Corpufcles 3 yet even upon 

 this fuppofiuon it may be faid, that 

 thefe particles contribute to the ef- 

 fect that is produced, but by facilita- 

 ting or procuring^ by their oppor- 

 tune
