Wax And Wafers. Francis Rousseau, a native of Auxerre, who travelled a long; time in Persia, Pegu, and other parts of the East Indies, and who, in 1692, resided St. Domingo, was the inventor of sealing-wax. A lady, of the name of Longueville, made this wax known at court, and caused Louis XIII. to use it; after which it was purchased and used throughout Paris. By this article, Rousseau, before the expiration of a year, gained 50,000 livres. The oldest seal with a red wafer ever yet found is on a letter written by Dr. Krapf, at Spires, in the year 1624, to the Government at Bareuth.
