sufficiently concentrated to deposit crystals. It is quite likely that in

only one of them can be proved by the microscope.

Born 1840. Dizp SEPTEMBER 27, 1907. 
By the death of Professor Charles Stewart, which has occurred 
after a somewhat protracted illness, the Royal College of Surgeons 
of England has lost one who has successtully filled the office of 
conservator of the museum for the past twenty-three years. After 
attending as a medical student at St. Bartholomew’s Hospital 
Professor Stewart became a member of the Royal College of Surgeons 
in the year 1862. He was admitted a Fellow of the Linnean Society 
in 1866, and was President of that body during the years 1890 
to 1894, and in the following year served as Vice-President. 
Professor Stewart was also a Fellow and Vice-President of the Royal 
Microscopical Society, and became one of its honorary secretaries in 
1878. He was Treasurer of the Anatomical Society of Great Britain 
and Ireland from its foundation until 1891. During the period 
1894-1897 he held the office of Fullerian Professor of Physiology at 
the Royal Institution, and delivered several evening lectures at the 
same place. He was admitted a Fellow of the Royal Society in 1896, 
and obtained the honorary LL.D. of Aberdeen University. Before 
being appointed Conservator of the College of Surgeons’ Museum 
Professor Stewart was curator of the museum of St. Thomas's 
Hospital, lecturer on Comparative Anatomy, and joint lecturer with 
Professor John Harley on Physiology at that institution. He was 
subsequently appointed Professor of Biology and Physiology at 
Bedford College. In the year following his appointment at the 
College of Surgeons he was elected Hunterian Professor of Human 
and Comparative Anatomy, and held the post until the year 1894. 
The true value of Professor Stewart’s scientific work is not to be 
judged solely by his writings, which, in spite of the vast extent of his 
knowledge gained from his personal observations, were comparatively 
few in number, but it is to be seen rather on the shelves of the 
College Museum in the unrivalled series of preparations and dissections 
by which he sought, in continuation of the work of previous 
Conservators, to illustrate important phases in the evolution of the 
organic world and thus to amplify the original scheme of John Hunter, 
whose collection forms the nucleus of the College museum. Professor
