Barrington-Shute, William Wildman, 2nd Viscount Barrington, 1717-1793.
The collection offer new insights into the 'unofficial' views and deliberations held by Board of Longitude members, and reveal, for example, that the Board was considering disbanding in the mid 1760s. They include personal notes made by Barrington at Board meetings, and a rare unbound pamphlet, 'A Narrative of the Proceedings' (1765), which makes Harrison's case for the Longitude reward, following the trials of his fourth timekeeper, H4. A selection of the documents is on display at the Royal Observatory, alongside the four famous timepieces made by John Harrison between 1730 and 1759. Further information about Harrison and his timekeepers can be found on the National Maritime Museum's website, and digitised copies of items within the collection are available in the <a href="http://cudl.lib.cam.ac.uk/view/MS-BGN-00000/1">Board of Longitude Digital Archive</a>.
