Lizars claimed in print in 1838 that
James Syme had endangered a patient's life and ruined his health by want of care in averting
hemorrhage; Syme had been an unsuccessful competitor for the post held by Lizars. Syme replied with a lawsuit, in which he claimed damages for false and malicious statement. The suit was successful, but with token damages only. Syme, however, had a probable role in dissuading the College of Surgeons from re-electing a professor of surgery when Lizars's tenure of the office finished. Lizars published further criticism, in 1851, of external
urethrotomy as practised by Syme. Syme retaliated with a comprehensive personal attack; this time Lizars sued, and lost. Lizars had become eccentric, and was unable to obtain further public appointment; and his private practice declined. ==Death==
