Was pleased to receive JH's letter requesting him to communicate the subject to the Society. Has been busy preparing the Annual Report so has not had time to follow up Mr. Traye's papers.

Has sent on the correspondence about K. L. C. Rümker's Southern Catalogue. Has recorded his vote in favor of the £150 for the reduction. Proposes sending his eldest son to Paris to study French and Art.

Thanks for pictures of Mars; speculates on the atmospheres of some planets.

Thanks for fine engravings; is concerned about the 'miraculous phenomena' depicted on some other people's engravings, 'especially American ones.'

Thanks for the diary and pocket book. Sees that A. V. Guillemin has published an illustrated Astronomy [Le ciel (Paris, 1864)]. Thinks there is scope for publishing a volume of engravings of astronomical objects. Gives his own idea for the construction of a photometer.

Returns the certificates duly signed and also Angelo Secchi's letter, which he was pleased to see. Elaborates on the possible causes of James Nasmyth's 'willow leaves.'
