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.
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.
Was indebted to JH for the names of the satellites of Uranus. Will find details of his observations in the R.A.S.M.N. Gives volumes. Is thinking of returning to Malta and erect a larger telescope.
Wishes all success to his proposed visit to Malta. Has been able to find the volumes of R.A.S.M.N. Comments on WL's system of levers for his telescope.
Thanks for his suggestions respecting the mode of observation by collimator; will give it careful consideration. Sends two photographs of the method of mounting his observation tower.
Is dismayed to find in the new edition of his own Outlines Astr. that he has attributed the discovery of Hyperion to W. R. Dawes without crediting WL; will have this corrected in a future edition.
Do not let the error in Outlines Astr. disturb him; he quite understands. The 4-foot telescope proceeds. The speculum has been polished and awaits trial. If JH is attending the B.A.A.S. meeting hopes he will visit Lassell.
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.
Discusses installation of a 4-ft. aperture equatorial telescope. Describes plans for a glass polishing machine in great detail.
Comments on WL's information on telescope construction, and adds some of JH's own experience.
Sends a lithograph of the 4-ft. aperture equatorial. Has made no observations with it yet. Had difficulty with the surface of the speculum. Comments on the drawing and on the use of the instrument. Cannot recollect seeing any of the irregularities pointed out by JH in his letter.
Comments on WL's 4-foot equatorial telescope of which WL sent JH a lithograph [see WL's 1860-2-8].
Pointing out the reasons for some apparent discrepancies in the drawing of his telescope. The drawing was hurriedly done by his daughter.
Comments on WL's nebulae diagrams and asks for more.
Was grateful for the copy of JH's article on the telescope. Sends parcels containing two specimens of 4-ft. specula; comments on these. Weather has been unsuitable for observations.
Is on the point of departure for Malta and would welcome letters of introduction from JH.
Thanks JH for his efforts in having Sir Benjamin Brodie provide letters of introduction for WL's time in Malta.
Details about WL's preparation for departure for Malta.
About WL's activity in setting up his observatory.
As JH is preparing a catalogue of all known nebulae, would WL please provide a complete listing of all he has seen.
Recently observed nebulae. Changes in island climate reduce observation time. Happy that JH plans to publish all nebulae in one catalogue. Has no new ones to offer. Observations of Saturn's rings. WL's telescope.
