_February 1st._--For the last week the King of Prussia and his activity have occupied the world. He has made a very favourable impression here. In person he is common-looking, not remarkable in any way; his manners are particularly frank, cordial, and good-humoured; he is very curious, and takes a lively interest in all he sees, and has, by all accounts, been struck with great admiration at the conduct and bearing of the people, as well as the grandeur and magnificence he has found both at Court and elsewhere. Whether the order, and more especially the loyalty, he has witnessed, will induce him to entertain with more complacency the idea of a free constitution for his own kingdom, remains to be seen, not that what he finds here ought necessarily to imply that results equally happy would follow the concession of liberal constitutions in Prussia. He has been in London almost every day from Windsor, one day breakfasting with Peel, who collected the men of letters and science and the most distinguished artists to meet him. On Sunday he went to church at St. Paul's, and then lunched with the Lord Mayor. Another day he went to Westminster Abbey, when he evinced great curiosity to learn all the local details of the Queen's coronation. Yesterday he went in the morning and paid a visit to Mrs. Fry, with whom he went to Coldbath Fields prison; in the evening to Drury Lane. He wanted to see one of Shakespeare's plays, and had no other opportunity, so he got the play acted at six instead of seven, and made the Duke of Sutherland, with whom he was to dine, have his dinner at nine. He asked for 'Macbeth,' but they told him it would take a month to get it up. They gave him the choice of the 'Merchant of Venice' or the 'Two Gentlemen of Verona,' and he took the latter. Nothing could exceed the magnificence of the _fête_ the Duke of Sutherland gave him, dinner and party after it. [Sidenote: THE DUKE OF BUCKINGHAM RESIGNS.]
