  <dc:title>Paper, 'A letter from the Revd [Reverend] Father Felix Bernard's to the Royal Society, consider'd' by [William Jones]</dc:title>
  <dc:description>Jones discusses Felix Bernard's invention of a machine consisting of two springs with intermediate wheels which produce perpetual motion, one spring constantly winding the other. Jones had not seen a model of the machine and so debates whether or not the motion of the machine could really be perpetual. He also discusses Bernard's claim that a friend of his had found the quadrature of the circle, which Jones believes to be unlikely.
