To prepare for the trial, the bank sent Mr. Donovan, an intelligent officer in Edinburgh, from Glasgow to London, to trace the route the robbers had taken nine years before, and to procure witnesses. Donovan was successful, and brought down with him Scoltop, who had prepared the instruments by means of which the robbery was effected, Mrs. Huffey White, several waiters at inns, and even Mrs. Mackcoull, who consented to give evidence against her husband. The most eminent lawyers at the Scotch bar were engaged on each side; and on the morning of the trial, May the 11th 1820, every avenue to the court was crowded to excess, so intense was the interest excited by the case. The result was against Mackcoull, for the witnesses completely established his guilt; and so unexpected was the appearance of some of them to him, that he frequently ran out of court, and on seeing Scoltop actually swooned away. Mackcoull's career of villany was now near its end. On the 19th of June he was indicted for the robbery, in the High Court of Justiciary; and the same witnesses being again examined, the jury returned a verdict of Guilty--Death. Towards the conclusion of the trial Mackcoull often looked about him with a kind of vacant stare, and was observed frequently to mutter and grind his teeth. When the verdict was announced he gave a malignant grin; and when sentence was passed, he bowed respectfully to the court. On being carried back to jail his fortitude forsook him, and he appeared overwhelmed with despair. At this moment he said with emotion, "Had not the eye of God been upon me, such a connected chain of evidence never could have been brought forward!" His spirits, however, soon returned, and he received the number of visitors, who were led by curiosity to see him, with great cheerfulness. Although he had treated his wife with great unkindness, she now came forward and supplied him during his imprisonment with every luxury in profusion. She also made application for a reprieve; and whether from her exertion or not, on the 14th of July a respite arrived, and in three weeks after a reprieve during his majesty's pleasure. In the month of August, the wretched prisoner fell into a natural decline, and his mental faculties completely forsook him. In the course of a short time his hair, which had been previously nearly jet black, became a silver gray, and at length he died in the county jail of Edinburgh on the 22nd day of December 1820, and was decently interred at the expense of his wife, in the Calton burying-ground.
