Paper, 'Proposals about the machine to get good air for respiration and vegetation' by D [Denis] Papin Papin describes his machine consisting of a chamber with a pump, large enough to accommodate a man. He then details the costs of constructing the chamber. His imagined uses for the chamber are found at CLP/3ii/6. Also includes a short letter from Papin to Hans Sloane dated 18 January 1709, explaining that he attempted to deliver his paper twice to Isaac Newton's house but that Newton was not home on either occasion.
