Since the assassination of the Czar we have looked with interest for a description of the weapon used by the assassin as it was rumored it was of novel construction and of great power. All attempted descriptions that we have met have been meagre and imperfect, the most detailed, and that claiming the greatest accuracy, being found in Le Gaulois of March 29th. From this we gather that ‘the bomb consisted of a sheet iron cylindrical box 15 cm. high and 10 cm. in diameter. ON the left hand side was a copper tube 9 mm. in diameter and extending the whole length of the box from top to bottom. This enclosed a hermetically sealed glass tube of equal length and 3 mm. in diameter, which was filled with sulphuric acid. The space about the glass tube within the copper tube was filled with a mixture of Berthollet’s salt and a salt of antimony. At the longitudinal centre of this copper tube its diameter was increased to 3.1 mm. for a distance of 1.9 mm., in order to admit of a disc of lead of slightly smaller dimensions which was perforated and free to slide a small distance on the glass tube.
