C4J But, to do him juflice, it mufl be confefled he has taken care elfewhere (a) to lay down the di- flinguifhing Marks of Sulphur and ks Hepnr; but it is alfo obfervable that moll of thofe marks are actually found in the waters called Sulphureous, or in their natural produds, as fhall be exempli¬ fied in the fequel. 2. The congruous appearances exhibited by the Sulphur and Phlogijion in the above Table fhould feem to fhew their fimilar nature, except in the greater proportion of acid in the former ; but ac¬ cording to our Author, thefe two fubflances are wholly diflindt, and fb far diflimilar that the ap¬ pearances common to Sulphur and Phlogijion in the above Table, are not owing to Sulphur qua SuU phur^ but to the difengaged Phlogijion or inflam¬ mable principle alone (b)^ fo that the dilcolouring of Silver, and of the Precipitates exhibked by the folution of Silver and Lead, which have hitherto been laid down as marks of Sulphur^ are by him deftroyed as fuch and appropriated to the Phlogijion: For (proceeds he) Before the Phlogiflion is fet at liberty by breaking in fome fort its conneSlion with the univerfal acid in Sulphur, by the interpofition of ale all s^ lime or other matters that abforb or overcome the acif Sulphur alone^ or the concrete Sulphur^ is not found to gild Silver or tinge it yellow ; but as foon as the connebiion aforefaid is broke^ and the folution of Sulphur is made by lime or alcalis^ then- the difen^. gaged Phlogilton flies ofl] Jirikes the fenfe of fmelU ing with a putrid Jiench^ tarnifloes Silver^ Sic.
