[William Prout, physician and chemist.] Autograph Letter Signed ('Wm Prout'), discussing with a fellow practitioner the treatment for diabetes of 'Mr Brown', and of Brown's wife.

4pp, 12mo. Bifolium. In good condition, lightly aged, with labels from mount adhering. Folded twice. The last four lines of the letter, and the name of the recipient (a fellow-practioner), have been deleted, and a newspaper notice of Prout's death has been laid down over this. An interesting letter, casting light on medical consultation and co-operation in Early Victorian London. The letter begins: 'Sir, | Your patient Mr Brown, in the absence of Dr Hodgkin, [the celebrated pathologist Thomas Hodgkin] authorised me to open your letter to Dr. H. containing some particulars of Mr B's case. This will explain the object of my present address to you.' Agreeing with the diagnosis of diabetes, he describes the treatment he has put in place, adding that he 'found little to direct regarding diet which had been completely neglected'. He 'allowed him, if they agreed with him, green vegetables. My prescription he will shew you.' Two paragraphs deal with the effects of 'a severe attack of diarrhoea'. He discusses 'the care of Mrs B. who in the absence of Dr. H. likewise consulted me'. He describes his prescription, explaining that the preparation he prefers 'is that made by Hooper Pall Mall East Castle Street'.
