In 1676 our partners all established themselves at Paris, where they added to their company three collaborators, all important in different ways: the quack Rabel, a physician celebrated in his day; a rich banker of Paris named Pierre Cadelan, secretary to the king; and a young Parlement advocate named Jean Terron du Clausel. Du Clausel lodged with Vanens in the Rue d'Anjou, in a house which had for sign _Le Petit Hôtel d'Angleterre_. He was a valuable addition to the band, because he could distil at pleasure, being 'licensed.' Rabel seems to have been possessed of considerable real science. Rabel water, which he invented, is still used in our own day--a mixture of alcohol and sulphuric acid, which acts as an astringent in cases of hæmorrhage. Rabel had compounded another elixir, whose innumerable merits were celebrated in notices in prose and verse which the most glowing of modern advertisements have not surpassed. Cadelan supplied funds. Bodin speaks in very precise terms about the alchemists: 'They extract the quintessence of plants, and make admirable and salutary oils and waters, and discourse subtly on the virtues and the transmutation of metals; but they also make false money.' At the moment when Cadelan and his associates were arrested, he was on the point of farming the Paris mint. Was this in order to make false _louis d'or_, as historians have supposed? We believe rather that it was to find means of circulating the products of the alchemical experiments of his associates, for by that time they had no manner of doubt about the efficacy of Chasteuil's formulae. A bar of silver cast by Vanens, and taken by Bachimont to the mint, had just been accepted there at a good price as pure metal. It is scarcely necessary to add that this could only have been due to an error of the mint official; this famous silver made out of copper by Vanens and Chasteuil was nothing but 'white metal.' Nevertheless, it was a success which opened before the eyes of our partners splendid vistas of future wealth. When Louis de Vanens was arrested on December 5, 1677, Louvois believed that he had seized a spy. But he had put his hand on an alchemist, and soon the whole band--Terron, Cadelan, Monsieur and Madame Bachimont, Barthomynat (known as La Chaboissière), de Vanens' valet--were laid by the heels, some in the Bastille, the others at Pierre-en-Cize. Chasteuil had just died quietly at Verceil. Rabel had escaped into England, where Charles II lodged and fed him, gave him a pension, and loaded him with presents. Later he returned to France, and was incarcerated in his turn.
