Circumstances closely following on this, however, awakened grave suspicions. Mrs. Pritchard died shortly after her mother, and a report was circulated that she had succumbed to gastric fever. The family grave at the Grange was fixed on as the place of interment, and arrangements were made for the funeral without delay. The body was taken to Edinburgh by rail, and Dr. Pritchard accompanied it to the house of his father-in-law, where it was to await interment. The deaths of the two ladies occurring within so short an interval of each other, coupled with certain hints which they had received, set the police on the alert, and while Dr. Pritchard was absent in Edinburgh they instituted inquiries, which led to a warrant being issued for his apprehension. On his return to Glasgow, previous to the day fixed for the funeral, he was arrested at the railway station in Queen Street and conveyed to the police offices. Meanwhile the authorities had transmitted to Edinburgh information of what had been done, and at the same time had issued a warrant for a post-mortem examination of the body of Mrs. Pritchard. This was entrusted to Professor Douglas Maclagan, assisted by Drs. Arthur Gamgee and Littlejohn. The result of the post-mortem proved that death had not resulted from natural causes, and a subsequent examination disclosed the presence of minute particles of antimony in the liver. The case now assumed a grave and mysterious aspect, and the authorities resolved to carry the investigations further. The next step was to order the exhumation of the body of Mrs. Taylor. This having been effected, the internal organs were submitted to analysis by Professor Maclagan, Dr. Littlejohn, and Professor Penny of Glasgow, who, after a protracted examination, reported that the death of Mrs. Taylor, like that of her daughter, was due to poisoning by antimony. On these facts being elicited, Dr. Pritchard was fully committed on the charge of murdering Jane Taylor his mother-in-law and Mary Jane Pritchard his wife. The trial opened on July 3, 1865, at the High Court of Justiciary, Edinburgh, before the Lord Justice-Clerk, Lord Ardmillan, and Lord Jervis-woode, the Solicitor-General prosecuting for the Crown, while the prisoner was defended by Messrs. A. R. Clark, Watson, and Brand. Evidence was given that Mrs. Pritchard was first taken ill in the October of 1864, with constant vomiting, often accompanied by severe cramp. After being treated by her husband for some time, and getting no better, at her own request a Dr. Gairdner was called in, and her mother, Mrs. Taylor, came from Edinburgh to nurse her. While on this visit to her daughter, Mrs. Taylor, on February 24, complained of feeling unwell. The next day she was found insensible, sitting on her chair in her daughter's room, and died the same night. From this time Mrs. Pritchard got gradually worse, and died within three weeks afterwards.
