Thanks HO for JH's election to the Royal Academy of Copenhagen. Comments on some chemical and magnetical experiments.
Indebted to Smith's publications for the progress he has made in botany; offers to send 'Lichen' specimens not in "English botany" for Smith's opinion at later date, and now sends others, including: 'Parmelia conoplea', 'P. subiginosa', 'P. plumbra', 'P. ambigua', 'P. farrea'; observations. He and Mr Knight found 'Targionia hypophylla' last summer in Radnorshire, also found in Montgomeryshire.
Requests that Smith mark the specimens he has sent in a particular way. Remarks on habitats of 'Parmelia scrobiculata', 'P. aquila', and 'P. perforata'.
Errors in equinoctial time calculated by John Pond. Suggests limiting decimal places in value of equinoctial time to reflect this uncertainty. Making error uniform will make it awkward to alter future almanacs.
Resolved puzzle about sidereal year, which needs better definition. Error between true and nominal positions prevents TY adopting 'equinoctial time' for chronology investigations.
Comments on several experiments with spectra passing through glass films.
A ball and two concerts at Shrewsbury; guests at the Darwins’: Mr and Mrs Mathew, three Mr Clives, Emma Wedgwood.

Thanks for turkey and specimens of 'Dianthus'. [Samuel Goodenough] ill. Fonthill Abbey and grounds purchased by [John] Benett [(1773-1852), his brother-in-law], the walks and drives to kept in good order. The abbey itself is in ruins, mentions the tower falling with a "tremendous crash" and the previous owner, [John] Farquhar [(1751-1826)], having a narrow escape. Acquired work on Brazilian ferns.
