Sudden demolition of Board of Longitude. TY is left as superintendent [of Nautical Almanac]. Notes quality of J. F. Encke's almanac for 1830. Should English compete with German astronomers, or discontinue almanac supplements? TY's paper on 'Astronomical Chronology' in W. T. Brande's [Quarterly Journal of Science and Art] illustrates JH's equatorial time.

Is now prepared to write a signed article on light requested by DL [see JH's 1828-7-25]; JH encourages DL to ask William Whewell, W. H. Fitton, and George Peacock to write as well; recommends against use of color printing of pictures as the reproduction is too poor.

Encourages TY to publish 1829 supplement to Nautical Almanac. JH originally proposed supplement to introduce improvements that would bring N. A. to be like Encke's Ephemeris. That is all ended now. English are dropping behind French and Germans in science. JH refuses to accept money from government 'which treats its agents so cavalierly.' Reduction of Parramatta [Australia] observations. Did not see TY's paper in W. T. Brande's [Quarterly Journal of Science and Art], but objects to substitution of true for mean equinox.
Will not hold JH responsible for accuracy of William Richardson's computations. No instructions yet from Admiralty about Nautical Almanac, which goes to press soon. TY will insert JH's equinoctial time. Notes two works by A. F. C. Kollman on harmony and [Beck] on 'thorough-bass.'
