bling hall, and precipitate to the bottom. The fubfidence of 

 tlie lime, therefore, and the appearance of granulated fait, mark 

 -nhe point of time, when the pickle fliould be drawn into the 

 faJt room. In this lad ftage of the procefs, the liquor from fur-

valuable article is progrefTmg to fuch extent and perfe(51:ion, as
