Six months after, a manufacturer, who as early as 1857 had tried to get patented in France the patented discovery of Perkins, sold to a manufacturer of chemical produce a process copied from the discovery of Hofmann, by which the red of aniline could be manufactured by the reaction of the bi-chloride of tin. The Patent was granted, and the produce manufactured. But very soon after, in France and abroad, more advantageous and more scientific methods, preferable to the patented one, were found.
All the French manufacturers who tried to use any of these new processes were prosecuted and condemned for infringement on the right of the patentee. It then followed that one kilogramme of red of aniline was sold abroad for £12, and the monopolisers sold it for £40 in France.
This could not last, particularly after the treaty of commerce, by which printed and dyed goods could be introduced. Manufacturers threatened to give up work, and the patentee thought proper to reduce his prices.
But another result, no less fatal to French interests, soon followed.
The most intelligent manufacturers of colouring-stuffs, those who were at the head of that branch of industry, and had concentrated in Paris, Lyons, and Mulhouse the fabrication of the finest and most delicate dyes for the home and foreign market, went to establish new factories across the frontiers.
The existing Patent prevented them from satisfying the demands of their customers abroad, who required some aniline colours, and they were obliged to carry their industry to foreign parts.
The following is the list of the manufacturers who have founded new establishments beyond the reach of the monopolising Patent:—
A. Schlumberger, of Mulhouse, new factory at Bâle (Switzerland); Jean Feer, of Strasburg, new factory at Bâle; Peterson and Seikler, of Saint Denis, new factory at Bâle; Poirrier and Chappal, of Paris, new factory at Zurich; Monnet and Dury, of Lyons, new factory at Geneve.
Five other establishments, raised by Swiss people but under the direction of Frenchmen, are being founded at Bâle, Zurich, Glaris, and Saint Gall. Then there are still to be founded, the factory of M. A. Wurtz, brother to Professor Wurtz at Leipsic; another, by M. O. Meister at Chemnitz; a French factory at Elberfeld; three, also French, in Belgium; and three others in Switzerland.
