Nova analysis aquarum Medeviensium

A systematic chemical examination of several medicinal springs at Medevi presents physical descriptions, sampling procedures, and laboratory methods alongside qualitative reactions. The author reports temperatures, flow rates, taste and odor, and analyzes dissolved constituents with reagents that reveal notable iron content, limited free carbonic acid, and various precipitates from tests with tannin, ferrocyanide, nitric and oxalic acids. Methods for detecting hydrogen sulfide are evaluated and found partly ineffective except by odor. Experiments to liberate and measure dissolved gases using boiling and pneumatic apparatus are described, with discussion of methodological limitations and comparative notes on a nearby Loka spring and its mud.
