points to the reputation of a physician, and though such a mode of investigation might not prove unsuccessful in the skilful hands of Dr. Baillie, it must be allowed to be an example of dangerous tendency to those who have not had his means of acquiring knowledge, nor enjoyed the advantages of his great experience, nor have learned by the previous steps of education and good discipline to reason and judge correctly.” Halford then refers to the quickness with which a good physician makes up his mind on the nature of a disease; at that time it was oftener a guess than a process of reasoning. Baillie was one of the first to study pathology, and to bring into practice physical examination. MATTHEW BAILLIE was born on the 27th October 1761, in the manse of Shotts, Lanarkshire, his father having been Professor of Divinity in Glasgow University, his mother, Dorothea, sister of William and John Hunter. After two sessions at Glasgow, Baillie entered, in 1779, at Balliol College, Oxford, where he completed his M.D. in 1789. Residing during vacations with William Hunter, he became almost like a son to him, and assisted him much in making his anatomical preparations and superintending his dissecting-room. On the death of his uncle in 1783, he and Cruickshank continued the lectures with great success. Baillie lectured till 1799. One of his pupils said of him that his style, though not eloquent, irresistibly commanded attention; he appeared completely master of his subject, was exceedingly clear, concise, and condensed, and never at a loss for an appropriate word. He was always modest and unostentatious. When left sole heir of his uncle William, he at once transferred to John Hunter the family estate of Long Calderwood, to which he regarded him as entitled. Baillie’s principal work is pathological. In 1793 he published “The Morbid Anatomy of some of the most Important Parts of the Human Body,” and although pathology is now very different from what it was in his day, and his classification is not now useful, his facts, when properly interpreted, are still found excellent. The work met with very great success, and was translated into many European languages, besides going through five English editions in the author’s lifetime.
