Graves’s papers on Cholera embodied in his Clinical Lectures give an able history of the progress of that disease, and his researches led him to urge the foundation of a complete network of medical observatories to record especially the rise, progress, and character of disease, whether endemic or epidemic. Had he lived he might have done much to promote this object, only now and partially being attempted in the collective scheme for the investigation of disease under the auspices of the International Scientific Congress. But his labours shortened his life. He constantly corresponded with pupils all over the world; wrote much for periodical literature on subjects outside medicine, even doing the literary work of a patient whose family were in straitened circumstances. A disease of the liver finally cut him off, after a protracted illness borne with Christian fortitude and faith, on March 20, 1853. * * * * * Having been a leading teacher at Edinburgh for many years, JOHN HUGHES BENNETT impressed his individuality upon a larger number of students, and has been more generally recognised than Graves as a man of conspicuous merit. As a clinical teacher, as a physiologist, as a pathologist, as a therapeutist, he had high claims. He reformed the treatment both of pneumonia and of phthisis, and identified a disease, leucocythæmia, whose characters have proved the starting-point for most fruitful investigations. Bennett was born in London on August 31, 1812, and educated at the Grammar and Mount Radford Schools, Exeter. He was fortunate in having a cultivated mother, a lady of independent thought and spirit, and to her he owed the development of his marked literary and artistic tastes. As a boy she trained him in elocution, in which he afterwards excelled, and widened his thoughts by taking him again and again to the Continent. Deciding to study medicine, young Bennett was apprenticed to a Mr. Sedgwick of Maidstone, and for a short time attended St. Bartholomew’s Hospital. A little later, however, he decided to enter at Edinburgh University, and soon showed himself an assiduous student. He made the acquaintance of Edward Forbes, J. H. Balfour, John Reid, and others, who afterwards distinguished themselves, and became one of the Presidents of the Royal Medical Society. In 1837 he took the M.D. degree, being awarded a gold medal, on Syme’s recommendation, for the best surgical report, and being mentioned as worthy of a second medal by Sir Charles Bell. Bennett next studied for two years in Paris, founding the Parisian Medical Society, of which he was the first president. Other two years he devoted to study in German medical schools. The microscope and the stethoscope became in his hands familiar implements of research, and he already began to give forth the results of his study, contributing to Tweedie’s “Library of Medicine” a large proportion of the second volume dealing with diseases of the nervous system.
