| Description | Bundle of twenty-one letters to James Watt, from Mr Berthollet, Mr Brunel and the Chevalier Landriani, 1787- 1790. There is a bundle label, written in red ink, as follows: ' Letters from Monsieur Berthollet, Paris. 1787 - 1790. No. 1 to 21.' The letters are numbered in red ink. The letter numbered 1 (old no.) has '1787 to 1790' written on it in pencil. There are unnumbered paper enclosures. The letters were arranged in roughly chronological order with the most recent letter first. They have now been placed in chronological order with the earliest letter first. James Watt has written dockets with the name of the correspondent and the date, and some have a very brief summary. Any summary in square brackets has been provided by the cataloguer. |
