At an early period his bedroom was searched, but nothing was found but the laudanum bottle, and a little chloroform and camphor liniment which had been brought from another room. There were no remains of any solid poison in paper, glass, or tumbler, and nothing to indicate any poison had been taken. The post-mortem examination showed evidence of great gastric irritation, extending downwards, but there was no appearance of any disease in the body, or inflammation, congestion, or ulceration. It was left therefore to the chemical examination to show what was the irritating substance which had been introduced into the body, and supply a key to part of the mystery. The matters which had been vomited in the early stage of Mr. Bravo's illness had been thrown away; but, singular to relate, on examination of the leads of the house beneath the bedroom window, some portion of the matter was found undisturbed, although much rain had fallen and the greater part must have been washed away. This was carefully collected and handed to Professor Redwood for analysis. From this matter he extracted a large amount of antimony. Antimony was also discovered in the liver and other parts of the body, and it was concluded that altogether nearly forty grains of this poison must have been swallowed by the unfortunate man. How he came to swallow this enormous dose, whether the design was homicidal or suicidal, there was not the slightest evidence to show, or where the antimony was obtained. The whole affair was shrouded in mystery, and a mystery it remains. CHAPTER XIII THE CASE OF DR. PRITCHARD THE remarkable case of Dr. E. W. Pritchard of Glasgow, who was arrested and charged with murdering his wife and mother-in-law in that city in the year 1865, excited great interest at the time. The respectable position occupied by the accused man in society in Glasgow, and the practice as a physician which he had been enabled to attain in the course of his six years' residence there, awakened an unusual degree of attention in the public mind when the fact of his apprehension became known. The excitement was strengthened by the mystery invariably attached to the prosecution of all criminal inquiries in Scotland. It appears that for some time previous to her decease, Mrs. Pritchard had been in a delicate state of heath, and her mother, Mrs. Taylor, wife of Mr. Taylor, a silk weaver of Edinburgh, had gone to Glasgow to nurse her during her illness. Mrs. Taylor took up her abode in the house of Dr. Pritchard, and ministered to her daughter's comfort; but while so engaged she became ill, and died suddenly, about three weeks previous to the day on which the accused man was apprehended. The cause of death was assigned to apoplexy, and as Mrs. Taylor was about seventy years of age no public attention was awakened, and the body was conveyed to Edinburgh and buried in the Grange Cemetery.
