The collection of revolvers is unique in its way, and they are arranged about the walls of the museum with a decided eye to effect. They comprise weapons of every type and pattern. The two specially selected which appear above a very formidable dagger, evidently of Eastern manufacture--have their own peculiar history. The small one is the centre of attraction amongst a strange group of relics, consisting of a pair of links, the clasp of a purse, a little piece of steel which fitted inside a bracelet, and even a piece of a heel-tip. The heel-tip corresponded with the footprints of a suspected man, and, together with the remains of the trinkets, helped to bring a verdict of "Guilty." All these are associated with the Muswell Hill burglary in January, 1889. The revolver was used by one of three men--who were all subsequently sentenced to penal servitude for life--for shooting at Mr. Atkins. [Illustration: SHUTTER-CUTTER.] The larger revolver--which has an exceptionally heavy central fire--belonged to a top-hat shooter. On July 18th, 1884, a burglary was attempted at Hoxton. The police chased the burglars over the roofs of the houses, and a worthy named Wright, who had attempted to make himself look highly respectable in a silk hat, amused himself by clinging to a chimney-pot with one arm and using the other to practise firing with--the targets being the constables. Mr. Wright is not likely to play at this very risky pastime again. He is Her Majesty's guest for life in a palatial residence specially constructed for dispensing hospitality to such gentlemen. [Illustration: REVOLVERS AND DAGGER] The life-preservers are interesting. They hang in a delicious group just by the window. They are of all sorts and sizes. One swings on a piece of thick cord heavily loaded; another is made of rhinoceros hide. A pretty little invention in these specialities doubles up and fits the waistcoat pocket, the more popular example being made out of a piece of cord twisted round a short cane with a lead shot at both ends. The life-preservers have a curious companion--a pair of coverings, very rudely made out of coarse linen, for the feet, which the burglar puts over his boots out of thoughtful consideration for the slumbers of his victims. [Illustration: LIFE-PRESERVERS AND BOOT COVERS.] [Illustration: THE NEW NORTH ROAD MASK.] The disguises used--and treasured at New Scotland Yard--chiefly consist of false whiskers and beards. They are all made of dark crêpe hair and fastened to wires, which fit over the ear and keep them in position. The most original idea for concealing the face, however, is given a prominent place near the board on which are arranged the before-mentioned complete set of tools. It consists of a hard, black hat, attached to which is a piece of black American cloth with openings to give sight, cut very much to the size of old-fashioned goggles. This is fastened round the chin with a piece of cord. [Illustration: BEARDS, WHISKERS, ETC.]
