More discoveries of dynamite have been made this week. The

police on Thursday arrested a young man, named Norman, at a hotel in the Strand, who had in his possession 11 cwt. of nitro- glycerine, so pure that its force would be equal to that of a ton and a half of gunpowder. He maintains that he did not even know what the stuff was. They subsequently arrested a second man, named Wilson, in Nelson Square, Blackfriars, and a companion named Gallagher, the two possessing between them some £900, partly in American notes. They also were in possession of the liquid explosive. A fourth, named Dalton, has also been seized, and it is believed that this arrest is of the last importance, and that the police will now be able to track out the whole conspiracy. As a beginning, they have arrested one Whitehead in Birmingham, whose rooms were found to constitute a regular factory of nitro-glycerine. This man is believed not to be a Fenian, but a man who sells his knowledge of chemistry to the Secret Societies. It has been found necessary, among other precautions, to increase the rigour of watchfulness over Windsor Castle, which is threatened. Sir W. Harcourt stated on Thursday that the newspaper accounts were correct, and that he intended at once to propose alterations in the law affecting explosives. Not the least alarming part of the affair is the entire recklessness with which the accused appear to carry their explosives about. Wilson's stock would have laid Nelson Square in ruins. The accused are of superior education.
