Pelvilain who sold the waters and published ths book. Fourcy, an apothecary in the army and inspector-general in of the mineral waters in France, was a member of several scientific societies, including (he claims) the Royal Society of London)... Fourteen experiments on the mineral waters at Trye-le-Chateau are described. Fourcy concludes that they are ferruginous and that the iron is held in solution by other salts. He describes the formation of a little Prussian blue, indicating the presence of traces of iron solution. Very rare. Unknown to the usual bibliographers"].
