 vefTel is cooled gradually before the bal- 

 fam is poured off, the fulphur appears al- 

 moft like nitre when it chryflallizes, or a 

 vegetating fait branched out into long 

 ilender flalks. Sulphur likeways diffolves

 quantity, and with a fmaller degree of 

 heat. And it is to be obferved, that the 

 unredified or oily fpirit will difTolve more 

 fulphur than the clear and pure fpirit.
