[ 40 ] ration of regenerated fpar happened, and the fupernatant liquor was an alkali diflolved in water. 7 he fame precipitations were caufed hy the added folutions offal ammoniacum fixum y or of fal amcirunu. The above gelatina beino- edulcorated, dried, melted in a crucible, and afterwards pounded, had a cauftic tafte, ran per deliquium in a cellar, and was a true liquor ftlicum. ^" ame a PP e arances happened, when the alkali emp!oyed_ was the mineral fixed alkali.* 2$u "Volatile alkali being difiolved in this acid, formed a gelatinous lubftance; which, after being decanted, edulcorated, a^id evaporated to drynefs, proved to be a filex.' The lixivium had a tafte fqmewhat fimilar to fal ammoniacum Glauber:. After evaporation, fmall cryftais were formed, with the following properties. a. Being fublimated, a volatile alkali at firft went over, and afterwards a fal ammoniac, with a very four tafte. b. Being, diftilled with ohalk and water, all the volatile alkali went over. c ' rhefe cryftais being put into lime-water a regenerated fpar was precipitated. d. 1 he fame thing happened upon the acid being added to a folution of fal ammoniacum fixum, and the lixivium contained a common fal ammoniac. e. 7 hefe cryftais being added to a folution of chalk in nitrous acid, a regenerated Spar was precipitated. /• When they were added to a folution of filver m nitrous acid, a precipitation took place. I his precipitate being melted into a lblid lubftance, by means of the blowino-.pipe, a white cruft was formed upon the coal, around the regenerated filver. This
