Early in 1872 the present Chairman of the Westminster Union, W. J. Fraser, Esq., solicitor, asked me to visit the Rev. H. Watson, ex-master of Stockwell Grammar School, who was then located in Horsemonger Lane Gaol on the charge of killing his wife. I did so, and after an interview which lasted an hour, came away and wrote a report that in my judgment he was of unsound mind. I formed that opinion from the levity of his manner, his self-exaltation, his total indifference to his fate, the absence of all regret for what he had done, and the absolute want of any feeling on the subject. He was lost in the belief that his services in the education of youth precluded the possibility of any punishment for his deed. At the Old Bailey, as I was about being called upon to give evidence, the counsel who defended him, the late Sergeant Parry, called me over to tell me that they had decided not to call me as a witness, but only just to support the views of the others. He said, "We think you may be a dangerous witness." After asking me a few questions he said, "You can stand down." But I was not to stand down, for the prosecuting counsel, Mr. Poland, immediately proceeded to severely cross-examine me. But to all his questions I had my reply ready, and after some half hour's trial of questions and answers I managed to get out all the points on which I relied to prove Watson's mental unsoundness. When I got down Dr. Blandford said, "You have done well; you have convinced the judge;" which was shown in his summing up and in his after action at the Home Office.
