Mr. Hunter’s papers and greater works exhibit an extraordinary mind: he startles the reader by conclusions, the process by which they were reached being scarcely discernible. We attribute this in part to that defective education, which made him fail in explaining his own thoughts, and the course of reasoning by which he had arrived at his conclusions. The depth of his reflective powers may be estimated by the perusal of his papers on the apparently drowned, and on the stomach digested after death by its own fluids. The importance of discovering the possibility of such an occurrence as the last is manifest, when we consider its connexion with medical jurisprudence, and the probability of its giving rise to unfounded suspicions of poisoning. His most important papers were those on the muscularity of arteries; a fine piece of experimental reasoning, the neglect of which by our continental neighbours threw them back an age in the treatment of wounded arteries and aneurisms. But the grand discovery of Mr. Hunter was that of the life of the blood. If this idea surprise our readers, it did no less surprise the whole of the medical profession when it was first promulgated. Yet there is no doubt of the fact. It was demonstrated by the closest inspection of natural phenomena, and a happy suite of experiments, that the coagulation of the blood is an act of life. From this one fact, the pathologist was enabled to comprehend a great variety of phenomena, which, without it, must ever have remained obscure.
Mr. Hunter died of that alarming disease, _angina pectoris_: alarming, because it comes in paroxysms, accompanied with all the feelings of approaching death. These sensations are brought on by exertion or excitement. In St. George’s Hospital, the conduct of his colleagues had provoked him; he made no observations, but retiring into another room, suddenly expired, October 16, 1793.
After these details no man will deny that John Hunter possessed high genius, and that he employed his talents nobly. He was indeed of a family of genius: his younger brother was cut off early, but not until he had given promise of eminence. Dr. Hunter was, in our opinion, equal in talents to John, the subject of this memoir, though his mind received early a different bias. And in the next generation the celebrated Dr. Baillie, nephew to these brothers, contributed largely to the improvement of pathology, and afforded an instance of the most active benevolence joined to a plainness of manner most becoming in a physician. Joanna Baillie, his sister, still lives, honoured and esteemed, and will survive in her works as one of our most remarkable female writers.
