- Description
The confirmed minutes records detailed accounts and astronomical and navigational observations from expeditions to the Pacific. Lists of chronometers and other measuring and navigational instruments taken on Cook's second and third voyages are included, as are instructions to astronomers and copies of log books. Various astronomical and mathematical theories for establishing longitude were submitted for consideration, as were chronometer designs.
The Board of Longitude appraised methods of establishing longitude and thus improving navigation. The collection deals with accounts and minutes of meetings of the Board, which evaluated chronometers and other systems of ascertaining longitude. Arrangements were made for testing of such instruments and methods by their use on various expeditions, notably those of Captain Cook.
