1p, 4to. In good condition, lightly aged, with thin strip of paper from mount adhering to reverse, which is endorsed: 'An original letter of King William the Fourth when Duke of Clarence addressed to Dr Halliday'. Reads: 'Dear Sir, | I have received your letter from Ghent and immediately made application to General Torrens whose answer I now enclose: I shall be anxious to see your book and ever remain, | Yours sincerely, | William'. At the time of writing Halliday was an army surgeon. 'General Torrens' is Major-General Sir Henry Torrens (1779-1828), from 1820 Adjutant-General to the Forces. Within months he saw service at the Battle of Waterloo, and after the end of the Napoleonic Wars he became domestic physician to William, with whom, while William was Duke of Clarence, he travelled on the continent. The book referred to in the letter has not been identified. 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'.
