Thomas Young approved supplying [Richard] Copeland with two sextants and one mountain barometer.
'Our micrometer screws' are not in error. F. G. W. Struve's star measurements using Josef Fraunhofer's repeating micrometer agree well with JH's. So error must be in HK's observations.
Invites HK to dinner Saturday to meet James South and Alexis Bouvard.
Has found some errors in the sheets of computations HK sent. Lists these. Comments on astronomical work of [William] Richardson and on the reading of 'The repeal of the Longitude Acts Bill.'
