The "Augsburg Gazette" has the following from Munich, dated the 10th:—"Professor Liebig was last night giving a lecture on chemistry at the Palace, bfore Queen Maria, Queen Therssa, King Louis, the yeunger branches of the Royal family, and some persons belonging to the court, when a bottle of oxygen gas bsing improperly handed to him by his assistant, who took it for another bottle, an explosion took place, and the bottle flew into a thousand piece. Fortunately, the explosion occurred in an inner room, the door of which was open; still some fragments ot the glass passed through the door, and slightly wounded some members of the Royal party who were sitting in the trout rank. Queen Theresa was cut in the cheek, and the blood flowed in abundance; Princs Luitpold was slightly wounded in the forehead, Countess Luxburg in the chin, and Countess Sandizell in the head. None of these wounds will be of any consequence. The professor was also slightly injured, having escaped with his life by a sort of miracle." The 1000 left by Franklin to the city of Boston, to be let on interest to young unmarried artizans in sums not exceeding .100 sterling, now amounts to $15,280,55. Franklin estimated that it would reach $581,640 in one hundred years, but owing to losses it will probably reach about $400,000. One provision of the will was that when the fund should amount to $581,640, half a million of dollars should be appropriated to some public work, which should be judged to be of the most general utility to the inhabitants of Boston. The loans are now rarely applied for at all, and it is proposed that the fund be deposited in the Massachusetts Hospital Lif Insurance Co., and in the Savings Bank of Boston.
