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.'
