Thanks WH for his drawing of the comet, which JH will communicate to the R.A.S.
Describes a particularly brilliant aurora, which JH observed from Collingwood on the night of 6 May.
Has received observations of the comet from C. P. Smyth, which he may like to communicate to the R.A.S. Comments on the deplorable state of the Cape Town [?] Observatory.
Regarding FB's paper on the revision of the boundaries of the constellations.
Concerned that the Colonial governors were not provided with copies of the Standards Commission Report; will not be able to get to Switzerland this year.
Will be at the Visitation and intends to spend a few days in town. Has got the catalogue of objects for the star maps.
His views on the imperfections and lack of suitable instruments at the Cape Observatory.
Encourages AE to consider translating some mathematical works; additional comments on mathematics in general.
Thanks for the deodar seeds sent; accepts JL's offer of some young deodar plants. Needs instructions on planting these. Does JL have a copy of JH's 'On the Action of the Rays of the Solar Spectrum on Vegetable Colours, and on Some New Photographic Processes'?
JH sends some examples of a unique kind of latent photograph, and adds other comments about various aspects of photography. JH has seen a good aurora. He now agrees with A. C. Becquerel's theory of the spectrum.
Thanks FB for some papers; raises questions relating to remodelling the constellations of the southern sky.
Asks GA on behalf of F. W. Bessel, for unreduced positions of a star that FB wishes to examine for annual parallax.
Apologizes for confusion about F. W. Bessel's request [see GA's 1843-6-6], but JH had neglected to check date on FB's letter.
Will review all Gamma Virginis observations before revising orbit. Catalogue of major nebulae complete; will work on minor nebulae next.
Completed 'one of the most curious products' of JH's Cape Results: the map and catalog of the 'Nubecula major' region.
Comments on book on etymology forwarded by Sherwood & Co. [see 1843-5-26].
Sends JH's 1817 observations; cannot locate any he made in 1811. Tells WS Gamma Virginis measurements will take more time.
Discusses deficiencies in astronomical equipment at Cape's observatory, and troubles in observing comets, double stars, and other phenomena. Hopes equipment can be updated.
Regrets he will be unable to visit Cork for the B.A.A.S. meeting, but is conscious of the honor of the invitation.
Is expecting to be summoned to Slough, about repossessing JH's [and William Herschel's] old premises; this will affect JH's availability for a meeting [see GA's 1843-6-24].
