Five more London churches are to be immediately destroyed. Down with them! First down with St. Mildred's, in the Poultry. It was built by SIR CHRISTOPHER WREN, and somewhere about it rest the remains of THOMAS TUSSER, who wrote the "Five Hundred Points of Good Husbandry." Sweep it away, and then batter down St. Dionis Backchurch, also built by SIR CHRISTOPHER. There are monuments in it to the great benefactor to the Bodleian Library, and to the founder of the Saxon Lectureship in St. John's College, Oxford. Who cares? St. James's, Aldgate, is to be demolished: 'tis enough that Hebrews chiefly abide around that fane, and need it not. Out with St. Martin of Outwich; it hath stood less than a hundred years, and though it was consecrated by BISHOP PORTEUS, and holdeth fine old monuments, conserved through three centuries, away with it! Lastly (for the present) turn this pictured clown's pickaxe upon St. Anthony's, or St. Antholin's, Sise Lane. That, too, was the work of the Architect of St. Paul's, and sundry be the memories which our old dramatists and our WALTER SCOTT have hung on "St. Anthing's." It is very meet and right that the old City churches should all go, few persons now abiding near them on Sunday, and religion being a thing for Sunday. SIR CHRISTOPHER'S Cathedral, as it is also a Mausoleum, will probably be spared until some railway or tramway shall want the site. Yours, delighted, EROSTRATUS VANDAL. * * * * * ORGANS OF OFFENCE. ON Thursday last week a modification of the American Gatling Gun, called the "British Mitrailleuse," was tried for the first time at Woolwich. The following is a description of this benevolent machine:-- "It consists of ten barrels hooped together and revolving in the centre, and fitted into a carriage like that of an ordinary field-gun, which, at a short distance, it greatly resembles. The barrels and cartridges are similar to those of the Henry-Martini rifle--in diameter .45 in.; the cartridge-cases being of brass, and bottle-necked." Tremendous, however, as may be the execution which this weapon is capable of doing among a flock of soldiers, authorities are of opinion that, "like small arms generally, it must give way to rifled ordnance." On its trial:-- "Indeed, most of the Royal Artillery Officers present seemed to think that the machine-gun can never stand against Artillery, even if its delicate machinery did not become disarranged by mere musket-shot." So that a comparison is suggested to those who read, that when the "British Mitrailleuse" is made ready and placed in position--
