having passed his examination before the Faculty of Physicians and Surgeons of Glasgow, he returned to Dundee and married Margaret McDonald, the only daughter of Duncan McDonald, a well-known manufacturer of that town, and Margaret Rose, his wife. To Miss McDonald he had been betrothed for several years. He then became house surgeon in the Dundee Royal Infirmary, and having filled this position for about two years, gave it up, and entered into private practice, his office being in the same house in which he was born and married. In 1843 Dr. Wanless, accompanied by his wife, mother, brother, and sisters, with their husbands, emigrated to Canada, and ultimately settled in London, Ontario. While in this city the doctor built up a good practice, and as coroner for the city of London and county of Middlesex he was highly spoken of by the press for the luminous and logical way in which he presented evidence to his jurors. In 1849 he received his license from the College of Physicians and Surgeons of Lower Canada. One day, in 1859, as he was walking along a street in London to visit a patient, he observed Dr. Bull, a homœopathist, give some pellets to a man who had fallen out of a two-story window. Having a prejudice against homœopathy, he accosted Dr. Bull in these words, “Don’t you think shame of yourself in giving that useless trash to a man in that condition?” Dr. Bull rose up, in a defensive attitude, and said, “I have always taken you for a sensible man, and instead of acting as you have done in your persecutions of us, why don’t you try to test our remedies according to the law of cure? I will give you some of our books to read, and also some of our medicines for that purpose.” Dr. Wanless accepted the offer, and took the books and medicines, thinking that he would be able to expose what he then thought was a humbug. After studying the principle of homœopathy for some time he gave the medicines to some of his patients, strictly according to the principles of homœopathy, beginning with some cases which had resisted the allopathic treatment under his own care, and that of some of the ablest men in the country, keeping a strict account of the symptoms and disease, and the symptoms and pathogenesy of what the medicine would produce on the healthy body, and after carefully testing this method of practice for nearly two years, he found that, instead of persecuting the homœopathists, he would have to become a homœopathist himself. After thorough conviction of its benefits to his patients, like Paul with the Christians, and in order to carry out the practice of homœopathy with more efficiency, he ceased from practice in London, and devoted himself to renewed study at the age of fifty years, and obtained the degree of Bachelor of Medicine from the University of Toronto in 1861, and the degree of Doctor in Medicine from the same University in the following year, 1862. He then, in order to
