Materia Medica (1857), aud Professor of Medicine, in succession to
Dr. George Budd (1863). In 1886 he resigned this post, and was
elected by the Council, Emeritus Professor of Clinical Medicine, and
Consnlting Physician to the Hospital. Shortly after this he became
a Member of the Council of King's College, in which position he con
tinued to serve his alma mater until his death.
In 1883, Dr. Johnson was appointed by the Prince of Wales Con sulting Physician to the Royal College of Music; in 1885 he received the honour of being elected a member of the Atheneum Club, on the ground of his eminence in sciencc; in 1888 his past and present students and friends presented him with his portrait, painted by the late Mr. Frank Holl, R.A. This picture was publicly presented to him in the large theatre of King's College amid a crowd of his former colleagues and friends by Sir Joseph Lister. The scene will long be remembered by all those who heard Sir Joseph Lister's kindly words, and Dr. Johnson's emotional reply. In 1889 he was made Physician Extraordinary to the Queen, and in 1892 he received the honour of knighthood.
The following list comprises his principal contributions to litera- ture" On Diseases of the Kidney, their Pathology, Diagnosis, and Treatment" (1852); "Lectures on Bright's Disease" (1873); "Epi- demic Diarrhcea and Cholera" (1855); "Notes on Cholera" (1856); "The Laryngoscope" (1864); A Defence of Harvey as the Discoverer of the Circnlation of the Blood" (1884); this was a reply to certain criticisms evoked by his Harveian oration of 1882 In 1887 he published a collection of medical essays and lectures in wbich many of his former ideas were stated with new force. Sir George Johnson's scientific life was by no means a peaceful one, and led to much controversy; lie continued to take part in discussions arising from his work until the very last. In 1894, in a series of letters to the 'Lancet,' he maiutained, in opposition to Dr. Pavy, that normal urine contains no sugar, but that the principal reducing substance present is creatinine, a material which he and his son (Mr. G. S. Johnson) very thoroughly investigated. In 1889 he published an essay on "Asphyxia," in which he defended his well known views against those of his opponents. As late as 1895, a History of the Cholera Controversy,' in which Sir George played so prominent a part, appeared from his pen; and in the present year a similar book on 'The Pathology of the Contracted Granular Kidney' completed his long series of publications.
He married, in 1850, Charlotte Elizabeth, youngest daughter of the late Lieutenant White, of Addington. He was left a widower with five children ten years later.
The vigour of Sir George Johnson's mind remained uuimpairod to the last, but his bodily health was feeble. He suffered from paralysis
