The doings of forgers, if properly chronicled, would fill sufficient volumes to stock the library of any average mansion with as sensational a series of works as could be found--indeed, so would the operations of begging-letter writers, for the matter of that. The previous papers under the heading of "Crimes and Criminals" have particularly dealt with the relics at New Scotland Yard, and although it must be admitted that the mementos here of this particular branch of punishable professions are not peculiarly extensive, yet they are unquestionably highly instructive and interesting, and it is not proposed to deviate from the pivot round which our previous observations have been made. One glass case is practically given up to them. It is a "creepy" case. It contains the last clothes worn by a famous forger, whose action set the whole world talking for weeks--his silk hat, travelling cap with ear laps, pocket-handkerchief, collar, etc. It is not considered politic to mention his name. Close by is a poisoner's pill case, whose nefarious deeds in a neighbourhood "over the water," and in the immediate vicinity of Waterloo Bridge, made one shudder only a year or so ago. Then we come to the relics which call for more minute attention. [Illustration: PLATE USED FOR PRINTING FORGED RUSSIAN ROUBLE NOTES.] Here are the plates for printing, gelatine moulds, and specimens of notes, which form the relics of the case known as the "Forged Russian Rouble Notes," which had a run between the years 1868 and 1876. A glance at a frame containing samples of notes purporting to be for one, three, ten, twenty-five roubles, etc., will at once convince the observer that the Russian Consulate spoke truly when, at the hearing of the persons arrested, at the police-court, he said: "They are really splendid specimens of forgeries of the actual legitimate notes." In company with these are treasures associated with what is known as the "Ti Kroner Case." They consist of a cigar-box converted into what is generally believed to be a photographic camera, a negative--broken fortunately--of a Ti Kroner note, a note photographed on a piece of substantial box-wood, several specimens of forged notes, and a note pasted on to a piece of paper with three circles cut out of it. This is peculiarly interesting, for "the operator" has pencilled in the centre disc, "£10 clock here," in the left-hand disc, "£10 watch here," and in the right-hand circular space, "watch here." The excuse of the person on whose premises these were found was that he intended to use the Ti Kroner notes as a novel form of advertisement for clock and watch makers!--to distribute these notes, drop one or two carelessly in the streets, or leave them on the cushions of railway carriages; and when the thinkingly lucky finder hastily picked one up, popped it in his pocket, and waited until he got home to examine it, he found it was only, after all, an advertisement for Brown, the watchmaker, or
