John Hughes Bennett, an English physician, born in London, Aug. 31, 1812. He studied surgery under William Sedgwick and medicine in the university of Edinburgh, where he took his degree in 1837, receiving a medal for the best surgical report, while Sir Charles Bell highly commended his thesis on the "Physiology and Pathology of the Brain.'1 He afterward studied two years at Paris and two years in Germany. In 1843 he was appointed pathologist to the royal infirmary, Edinburgh; and in 1848 he succeeded Dr. Allen Thomson as professor of the institutes of medicine in Edinburgh university. He was (1841) the first in Great Britain to advocate the use of cod-liver oil for the cure of consumption, scrofula, and kindred diseases, and to deliver lectures on histology. He discovered a disease of the blood which he called leucocythaemia or white-cell blood. He also proved that the hemlock of the present day is the same drug by which Socrates was poisoned. His publications include "Inflammation of the Nervous Centres," " Treatise on Inflammation," "Cancerous and Cancroid Growths," "Pathology and Treatment of Molecular Consumption," "Treatment of Pulmonary Consumption," " Lectures on Molecular Physiology, Pathology, and Therapeutics," " Principles and Practice of Medicine," and "Pneumonia." His most important work, "On Clinical Medicine" (1856), has passed through many editions in both hemispheres, and has been translated into many languages.
