JH comments on quality of Georg Merz object glasses.
Agrees that some of JH's suggestions about meteor showers were probably unnecessary [see GA's 1848-1-29].
Is aware of T. J. Hussey's drawings [see GA's 1848-2-1]; needs information about P. A. Hansen's lunar theory for an appreciation JH is to provide.
Some additional details about JH's aunt Caroline [see JH's 1848-1-27].
JH must arrange for the celebration of Bishop's Observatory. Needs information on its equipment, achievements, and staff, e.g., on W. R. Dawes's and J. R. Hind's observations. Will contact Hind.
Needs clarification about John Lubbock's planetary theory; thanks for G. B. Airy's lunar reductions.
Returns [Max] Weisse's manuscript. He must say something about it and so has swallowed 'whole hog' what RS had written about it. Will make a mess [in his R.A.S. address] of John Lubbock's work on perturbations.
Lists a number of people JH called on but all were out. Received a gold medal with the head of the King of the Netherlands on it. Also received a 'very superb and truly Imperial' ring from 'the Duke.' [This, presumably, is the diamond ring he received from the Emperor of Austria.]
Regarding the originator of the R.A.S. Regarding his duties as trustee and other legal matters.
Gives directions for and raises questions concerning WW's contribution to JH's Admiralty Manual.
Paramatta Observatory has been broken up and is now defunct.
Received drafts from WB and Charles Wheatstone for Admiralty Manual. JH must edit and connect them. Promises to preserve WB's intent and to give full credit.
Surprised by GA's unhappiness with George Merz [see GA's 1848-2-17]; suggests GA seek information from Thomas Maclear at the Cape, who is getting a new telescope from George Merz.
Refers WT to reference work to check WT's experiments [see WT's 1848-2-4]. JH says he will perform no more experiments in physical optics.
