About the procedures WL uses when observing, and the responsibilities of an assistant.
After receiving testimonials of the highest order he has appointed [Albert?] Marth to be his assistant. Encloses some observations of nebulae. If JH's sons are visiting Malta he would be pleased to see them.
Was grateful for a copy of the proof sheets of JH's forthcoming 'Catalogue of Nebulae.' Comments on the Colonial book post. May discover a few hundred new nebulae but they are faint. Regrets to learn that JH's health is not good. Temperature has been very warm.
Encloses lithographs of some of his drawings of nebulae, and two tracings of [?] 2241. Has presented his large equatorial to Melbourne and invited the Astronomer Royal [G. B. Airy] to Malta to observe through the telescope before it is dispatched to Australia. Would also welcome a visit from JH.
Sending his impression, formed during a recent visit to Dublin, of the Great Telescope destined for Melbourne. Considers it a triumph of mechanical invention.
Comments on WL's finding a sixth star in the trapezium of Orion [see WL's 1842-3-10]; lists other catalogues that identify that star.
Comments on WL's observation of the seventh satellite of Saturn as noted in WL's 1846-8-26.
Believes that the observations WL has made are quite sufficient to establish the existence of the seventh satellite of Saturn.
Announces, to WL, the discovery of a new planet beyond Uranus, gives co-ordinates, and urges WL to look for satellites 'with all possible expedition.'
Ask WL's permission to make reference to WL's sighting of the seventh satellite of Saturn in JH's observations of all the satellites of Saturn.
Urges WL to make public his observations of the seventh satellite of Saturn as Otto Struve is about to announce his observation of the same body.
Suggests names for the satellites of Uranus, in response to a request from WL [see WL's 1851-11-3].
Is pleased to hear of the discovery of further satellites of Neptune.
Some question of Harvard University observer having observed the satellite [see JH's 1848-9-22] one day before WL.
Congratulations to WL on his discovery [see WL's 1851-11-3]; naming should occur once the various satellites have been described and verified.
Is willing to assist in obtaining letters of introduction for WL's projected trip to Malta.
Is preparing a new edition of Outlines Astr., and would like to know from WL the status of each of the satellites of Uranus and Neptune.
Asks for details of WL's system of speculum polishing and telescope construction as JH is preparing an article on telescopes for the Encyclopaedia Britannica.
Comments on WL's information on telescope construction, and adds some of JH's own experience.
Comments on WL's 4-foot equatorial telescope of which WL sent JH a lithograph [see WL's 1860-2-8].
