THE serious reverses of the French in the war with Prussia, are causing the infallible pope to act very much as Belshazzar did when he saw the handwriting on the wall. France finds it necessary to withdraw the French troops from Rome for home defense. These troops are all that has kept the pope in his position for years; and their withdrawal is the signal for the rallying of the patriotic Italians for the resistance of his usurpations. They are now hovering on the borders of his dominion to seize upon his temporal possessions, as soon as French bayonets shall have left that vicinity. The pope beseeches the empress of the French for at least one ship for his defense; and there is serious talk of his being obliged to leave Rome immediately for other quarters.
