Letter from William Macintosh, London, to Sir Joseph Banks He submits to the Royal Society, a model of a machine to raise "any reasonable quantity of water to any necessary height by a less power than any that has yet been discovered and upon a more simple and cheap construction"; the machine was shown by a man in poor circumstances when the writer was in Paris last winter; he recommended the inventor to send a model to England where the ingenuity of an alien would meet with encouragement and reward;as the inventor did nothing, Macintosh thought himself justified in having the model made and improving upon it. 26 October 1782
