ON THE FOREIGN CONTENTS OF MINERAL WATERS. ATTEMPTS to fubject to analyfis the various mineral fprings, muft foon have followed their introduction into medicine, ef- pecially thofe that pofleffed any remarkable fenfible properties; and accordingly, many very eminent chemifts have directed their attention to this object. Here, however, a very great difficulty prefented itfelf to the chemifts of every time, down to the period immediately preceding the introduction of the modern fyftem of chemiftry, which was the great volatility of the moft active contents in many of the moft curious and powerful waters, which efcaped in the ftate of gas, during the evaporation neceflary to exhibit in a folid form the faline and earthy particles that were held in folution. The efcape of thefe gafes could not but be noticed; and even fome of their chemical properties, as that of acidity in fixed air, and the fulphureous nature of hepatic air; andhence we find the terms volatile fpirit of vitriol, volatile fulphur, and the like; hence too the very perplexing difputes concerning the exiftence of fulphur, where the odour and other properties ftrongly indicated it, and yet w; iere none could then be prefented, as the refult of chemical analyfis. Modern che- mifts, by flow ftepSj and by improving gradually on the labours of their predeceflbrs, have arrived at a much more accurate knowled...« less
