In Berlin, from Tuesday, 31st May, 1740, day of the late King's death, till the Thursday following, the post was stopped and the gates closed; no estafette can be despatched, though Dickens and all the Ambassadors are busy writing. On the Thursday, Regiments, Officers, principal Officials having sworn, and the new King being fairly in the saddle, estafettes and post-boys shoot forth at the top of their speed; and Rumor, towards every point of the compass, apprises mankind what immense news there is. A King's Accession is always a hopeful phenomenon to the public; more especially a young King's, who has been talked of for his talents and aspirings, —for his sufferings, were it nothing more, —and whose ANTI-MACHIAVEL is understood to be in the press. Vaguely everywhere there has a notion gone abroad that this young King will prove considerable.
