At noon, on Tuesday, the 15th of January last, Mr. Eugéne Hamburger met, in the busy Metropolitan thoroughfare, “Holborn Viaduct,” a jewel dealer, named Jackson, with whom he had some slight business acquaintance. With the view of exhibiting his wares, Hamburger consented to accompany the dealer into an as yet unoccupied office of the latter on the Viaduct. Upon entering the room, Hamburger was about to take a parcel of pearls from his bag, when Jackson fired a pistol at him, wounding him in the head, and afterwards continued the assault by drawing a dagger and stabbing him. In the struggle that ensued, Hamburger succeeded in overpowering and disarming his assailant, who escaped from the room and disappeared. The wounded man thereafter proceeded home in a cab, and recovered from his injuries.
