![[->8 ] The fimplicity of the procefs for purifying fait here defcribed, and its cheapnefs, as it can be done for lefs than i~d. per buihel, will, it is hoped, recommend it to the atten- tion of the legiflature, and the practice of it ought to be enforced by adt of parliament at all the fait-works throughout Great Britain. The propriety of fuch an adl of the legiflature wifi not ftrike thofe who imagine the purity and quality of fait of little moment, and who are unacquainted with the great quantity of bittern or heterogeneous falts contained in it. The common fait made at Shields, and on the Frith of Forth, is found, by repeated trials, on an average, to contain one-tenth of its weight of thofe bitter putrefcible falts1, aiding inftead of preventing putrefa&ion. According to the above proportion, a bufhel of fait of 56 pounds, contains 5J- pounds o£ the falts already mentioned. This plan of purifying common fait muft be enforced by a£t of parliament at all the falt- works in Great Britain, before it would be prudent to prohibit the importation and life of foreign fait; becaufe, were it otherwife, and the purifyng of the fait left in the choice of the falt-makers, they might be tempted to fave the fmall espence the procefs is attended with* t](https://iiif.wellcomecollection.org/image/b28769478_0024.jp2/full/800%2C/0/default.jpg)
