Agrees to support C. P. Smyth for membership in R.S.L. Objects to C. P. Smyth's statement regarding his discoveries observing at high altitudes. Stresses importance of variable star work.
Success of C. P. Smyth's Teneriffe expedition pleases JH; anxious for declination of nebulae taken from high altitudes. Upset over G. J. Stoney's reproduction of JH's collimating telescope without giving him credit.
Discusses the naming of a Plateau of Brussels. Discusses names to go on list; gives JH's and Michael Faraday's recommendations.
Compliments WS on a written address. Describes how to set up a telescope to avoid unnecessary vibration; includes diagram.
Sends apologies to William Lassell for omission of discovery credit.
Has heard WS is publishing an English translation of François Arago's astronomical writings. Urges against including Arago's lectures if the Italian translation is indicative of their level of accuracy. Lists numerous errors in that edition. [Marked 'not sent.' Note added to CDraft (RS:HS 25.13.13) states: 'A letter differently worded but noting some of these points, but not all (for particular reasons) if I remember right was sent.'
Wishes to put WS's final version of Gamma Virginis orbit in new edition of his catalogue. Asks questions about Mediterranean.
Makes suggestion on freeing the Leviathan from its trapped position.
Pleased that WS included François Arago's lectures in his compilation. Believes the Italian edition could have been better edited. Remarks on the Leviathan problem.
Thanks WS for 'kind expressions on my behalf.' Believes these may be the last words he may write.
