A correspondent of the Journal de Francfort writes, on the 14th inst. from Berlin: -

"To the great surprise of the whole capital there was found this morning posted up at all the corners of the streets an announcement by the criminal tribunal that the ex-burgomaster TSCHECH, condemned to death for having attempted to assassinate the King, was executed this morning at Spandau. The judgment, which condemned him to be drawn by a hurdle and broken on the wheel, had been commuted by his Majesty's clemency into simple decapitation.

We know from the best authority that it was not without a severe struggle against a well known mildness of his disposition, and yielding only to arguments and considerations of the deepest gravity, that the Monarch was induced to sign the warrant.

Never, in modern times, has any execution taken place with so little publicity. Under the present reign, no such executions take place in Berlin; but for these purposes a spot is chosen near the fortress of Spandau, which is two miles from the capital.

Yesterday afternoon, two squadrons of the dragoons of the guard, on duty within the city, received orders to be ready to turn out at an unusually early hour this morning. One of these squadrons was posted near the Brandenburgh-gate, on the high road leading from Charlottenburg to Spandau; the other waited behind Charlottenburg for the carriages with the criminal, to escort it to the fortress.

The Governor of Spandau did not receive notice of the intended execution till last evening. In a case like this the concourse of spectators, which on such occasions is always great, would have been immense if previously made known; but those present this morning were very few. Even the inhabitants of Charlottenburg did not hear of it till after the return of the escort of the delinquent and the officers of justice, who filled four carriages.

Last night the chaplain of the prison paid his last visit to TSCHECH, who, as we learn from those who were in constant attendance upon him till the last moment relied upon being pardoned, and when the warrant was read to him he complained of having been deceived with false hopes. Nevertheless he ascended with great courage the mound on which he was to receive the fatal stroke. His last thoughts and words were devoted to the memory of his wife who has been dead several years, and to his only daughter, 19 years of age, whom he has left behind him.

From the time of the arrest of her father, she has been in kind hands. One report is, that she was permitted last night to take leave of her father; but other accounts state that, up to the present moment, she is kept in ignorance, not only of his execution, but even of his condemnation."
