A private letter from Hanover states that, precisely at twelve minutes to eleven in the morning on the ninth of the present November, his majesty King ERNEST was suddenly attacked by a violent fit of blue devils. All the court doctors were immediately summoned, and as immediately dismissed, by His Majesty, who sent for the Wizard of the North (recently appointed royal astrologer), to divine the mysterious cause of this so sudden melancholy. In a trice the mystery was solved--Queen Victoria "was happily delivered of a Prince!" His Majesty was immediately assisted to his chamber--put to bed--the curtains drawn--all the royal household ordered to wear list slippers--the one knocker to the palace was carefully tied up--and (on the departure of our courier) half a load of straw was already deposited beneath the window of the royal chamber. The sentinels on duty were prohibited from even sneezing, under pain of death, and all things in and about the palace, to use a brand new simile, were silent as the grave! "Whilst there was only the Princess Royal there were many hopes. There was hope from severe teething--hope from measles--hope from hooping-cough--but with the addition of a Prince of Wales, the hopes of Hanover are below par." But we pause. We will no further invade the sanctity of the sorrows of a king; merely observing, that what makes his Majesty very savage, makes hundreds of thousands of Englishmen mighty glad. There are now two cradles between the Crown of England and the White Horse of Hanover. We have a Prince of Wales! Whilst, however, England is throwing up its million caps in rapture at the advent, let it not be forgotten to whom we owe the royal baby. In the clamorousness of our joy the fact would have escaped us, had we not received a letter from Colonel SIBTHORP, who assures us that we owe a Prince of Wales entirely to the present cabinet; had the Whigs remained in office, the infant would inevitably have been a girl. 7.--THE FIRST MENTION OF THE PRINCE OF WALES. 1841.] The first number of _Punch_ came out on the 17th July, 1841, at 13, Wellington Street, Strand. There was a good demand for it, two editions of five thousand copies each being sold in two days. This demand was caused by advertising in various ways, including the distribution of 100,000 copies of a printed prospectus that was nearly identical with the draft whose first page has been shown here.
