Mr.Thomas Bond, F.R.C.S., surgeon to the Westminster Hospital, who destroyed himself yesterday morning in a fit of insanity by jumping out of a third-floor window at his house, 7, The Sanctuary, Westminster, was educated at King's College and King's College Hospital, and became a member of the Royal College of Surgeons in 1864. In 1865 he graduated as Bachelor of Medicine at the University of London, in 1866 as Bachelor of Surgery and gold medallist, and in the same year he became a Fellow by examination of the Royal College of Surgeons. After a short period of service with the Prussian Army he returned home, and was appointed assistant surgeon, and in due time surgeon to the Westminster Hospital and to the A division of police. By reason of the last-mentioned appointment his attention was early directed to medico-legal questions, in which he soon became an acknowledged expert ; and he has been concerned in the inquiries which have been made into almost all the important murder cases for many years past. His experience was also frequently appealed to in cases of real or alleged injuries received by railway passengers, and he was permanently retained as surgeon or consulting surgeon by both the Great Eastern and the Great Western Railway Companies. He contributed the article on "Railway Injuries" to Heath's "Dictionary of Surgery," and was an occasional contributor to the medical journals. Mr. Bond's health is understood to have been failing for some time past, and during the last few months he is said to have been the subject of melancholia, a form of insanity with depression in which attempts at suicide are not infrequent. It appears that he was left alone in his bedroom yesterday morning for a few moments, and that he jumped out of the window in his nightdress, falling a distance of more than 40ft. into the area, and dying almost immediately. Mr. Bond was twice married, first, to a daughter of the late Mr. Justice Hayes, by whom he leaves a family, and, secondly, to a lady who survives him.
