158 Of the Sulphur 



* peared to me a matter of importance to examine 



* its nature and characters, and learn to diftinguifh 

 c it from the other principles, &c.' 



c Common fulphur appears to me to have been 



* compounded of feveral matters; as (1.) an 

 c earth, (2.) a fait, (3.) a fatty, inflammable 



* matter, and (4.) fome metal. The three fir ft are, 

 c in weight or meafure in it, in a proportion of 

 c equality, nearly, and almoft conftitute the whole 

 c mafs of the fulphur ; from which I premife, that 



* by means of fublimation, it is purified from its 

 c fuperfluous earth, nothing of it remaining, but 

 c only fo much as the fire could have carried up 

 c along with the other principles,' (rather, that 

 nothing of it went over, but what the fire, &c.) 

 ' the produce of this fublimation we commonly 



* call flowers of fulphur. The metal, to be found 

 c in common fulphur, is in fo fmall a proportion, 



* that it may be overlooked.' 



What is become of the water which he after- 

 wards alledges as an efTential part of the fulphur, 

 though from a falfe inference ? How mail one, 

 from pure refined fulphur, which muft be what is 

 here meant, make out, and lay down for n e 1. a 

 peculiar earth, that belongs neither to n° 3, nor 

 n Q 4, but may be diftinguifhed from both ; feeing 

 thefe two parts are very fparingly, and the laft, 

 by his own conceflion, almoft undiftinguifhable 

 therein ? 



* By a Tingle procefs, the matters which make 

 c or conftitute common fulphur, are not readily 

 4 feparable from each other, both on the fcore 

 c of their clofe connection, and on account of the 

 ' great volatility of the inflammable, fatty matter
