In the month of September, 1850, I arrived at Frankfort-on-the-Maine. My passage through the principal cities of Germany, had been brilliantly marked by aerostatic ascensions; but, up to this day, no inhabitant of the Confederation had accompanied me, and the successful experiments at Paris of Messrs. Green, Godard, and Poitevin, had failed to induce the grave Germans to attempt aerial voyages.
