[Sir Edward Henry Sieveking, Physician in Ordinary to Queen Victoria.] Autograph Letter Signed ('E H Sieveking') to '[S J?] Clarke Esq',

1p, 12mo. In good condition, lightly aged, with thin strip of paper from mount adhering to blank reverse. The recipient is clearly the editor of a journal, who has solicited an article. Reads: 'My dear Sir | I am ashamed to say that I have nothing on hand that I care to publish, and I am afraid I am not as indefatigable with the pen as some of my friends. Pray accept my apologies and allow me to reserve myself for a future occasion'. From the distinguished autograph collection of the psychiatrist Richard Alfred Hunter (1923-1981), whose collection of 7000 works relating to psychiatry is now in Cambridge University Library. Hunter and his mother Ida Macalpine had a particular interest in the illness of King George III, and their book 'George III and the Mad Business' (1969) suggested the diagnosis of porphyria popularised by Alan Bennett in his play 'The Madness of George III'.
