IT is one of the best jokes of the times, that George Thompson, who first appeared as the stock fire-brand of American, should now be the patentee of a new "Universal Safety Match;" and that the special agents for the article should be John P. Jewett & Co., who formerly set the world on fire as publishers of "Uncle Tom's Cabin." Since Franklin drew the lightning from the skies and the scepter from tyrants, there has been no such melodramatic combination of offices. We charge nothing for this advertisement of the new matches—which must, according to the agents' circulars, be akin to those proverbially made in heaven—but it is becoming essential that their principle of safety should be applied to the more dangerous combustibles now stored in the Southern States.
