At last the Austrian Government threw off the mask. In its Constitution of the 4th of March, it proclaimed Austria an indivisible monarchy, with common finances, system of customs-duties, of military establishments, thereby effacing every barrier and distinction between the German and non-German provinces. This declaration was made in the face of resolutions and articles of the intended Federal Constitution which had been already passed by the Frankfort Assembly. It was the gauntlet of war thrown down to it by Austria, and the poor Assembly had no other choice but to take it up. This it did with a deal of blustering, which Austria, in the consciousness of her power, and of the utter nothingness of the Assembly, could well afford to allow to pass. And this precious representation, as it styled itself, of the German people, in order to revenge itself for this insult on the part of Austria, saw nothing better before it than to throw itself, hands and feet tied, at the feet of the Prussian Government. Incredible as it would seem, it bent its knees before the very ministers whom it had condemned as unconstitutional and anti-popular, and whose dismissal it had in vain insisted upon. The details of this disgraceful transaction, and the tragicomical events that followed, will form the subject of our next. LONDON, April, 1852. XV. THE TRIUMPH OF PRUSSIA. JULY 27th, 1852. We now come to the last chapter in the history of the German Revolution; the conflict of the National Assembly with the Governments of the different States, especially of Prussia; the insurrection of Southern and Western Germany, and its final overthrow by Prussia.
