Saturday 31 Aug 1844 (p. 2, col. 7-8) John NICHOLSON, who was convicted at our last Assizes, of stealing money from a letter in the Post-Office, (in which he was a clerk,) and sentenced to 10 years' transportation, was sent off from our gaol on Wednesday last to the Milbank Penitentiary. DEATH OF SIR P. MAXWELL.—It is with feelings of the most painful regret that we record the sudden and melancholy death of Sir Patrick MAXWELL, Bart., of Springkell, which took place on Tuesday morning last, about nine o'clock. On Monday night, Sir Patrick was returning from Sprinkell [sic] to Knockhill, where he was residing, when, on the road between Kirtlebridge and Ecclefechan, either his horse had fallen with him (which we are informed it had done a few days previous), or from some cause not ascertained, he was thrown on the road, and received a severe injury, which rendered him insensible. He was shortly after found and carried to the farm-house of Caldwellknow, when medical aid was procured, and every available means had recourse to, in order to effect his recovery, but all to no avail, as he gradually sank till next morning, when he expired. THE MURDER AT HIGH EIGHTON.—Two individuals, JEFFERSON and FLECK, who, it will be remembered, were witnesses on the inquest on the above case, are now in custody, charged with the murder of ROBSON, and will be examined this day at the County Justice Room, Gateshead.—Sir James GRAHAM, the Home Secretary, has offered a reward of £50 for the discovery and conviction of the murderer. EXECUTION OF MARK SHERWOOD.—This wretched man suffered the extreme penalty of the law on a scaffold erected on the Town Moor, within the race course, on Friday last. The crowd was immense—the majority appearing to be women—and was estimated at no less than thirty thousand. SHERWOOD made confession of his guilt to the Chaplain, but it merely amounts to the statements he made to his attorney, and on which his defence was founded.
