Letter from Thomas Robert Malthus of London to Rev George Turner, Kettleburgh, Wickham Market, [Suffolk], 28 Nov 1800. Referring to Malthus's tract An Investigation of the Causes of the present High Price of Provisions(1800). 'I sat up till two o'clock the evening before I went to Bath to finish it that it might come out before the meeting of Parliament.' Referring to the the famous Essay on the Principle of Population: 'The prevailing conversation about the pop[ulation] of the country has caused enquiries to be made about the Essay, which is now nowhere to be bought. This I hope will animate me to proceed in another edition, though to say the truth I feel at present very idle about it'.

Autograph, with signature.
