Patent Canceled on Match Chemical

The patent on sesquisulfid, a chemical used in the manufacture of matches, and held by the Diamond Match Company, has been canceled. Sesquisulfid is considered a harmless substitute for white phosphorous, which is claimed to cause necrosis and other diseases. President Taft urged the owner of the patent and license to permit the cancellation of the patent in order to insure protection against unnecessary disease, and recommended in his annual message that a tax be placed on the manufacture of white phosphorous matches.
