Letter from T Colley, 23 Leather Lane, London to Sir Joseph Banks Repeating his claim that his Tables, called Proportional or Logisitic Logarithims, answer all the astronomical computations with the greatest nicety. He also states he is very uneasy that having more than once requested that his two works and papers should be returned to him by Dr Maskelyne, he has had no reply. 31 July 1790
