Continues JH's defense of Laplace's writings on probabilities [see JH's 1845-12-22].
A note to accompany a working out in convenient form an example of Laplace's probability ideas. [Enclosure not found.]
Talks about considerations to be taken into account when building telescope specula, especially large ones.
Questions related to JH's 1846-9-26 having been asked by RR, JH writes to answer these questions.
Expresses opinions about the medal fiasco at the R.A.S., and in so doing, also defends G. B. Airy. JH is very concerned about the mean attacks being made on various people over the Neptune discovery controversy. Makes especially strong statements in a PS written on Feb. 21.
Thanks JM for a copy of the Correspondence of the Late J. Watt. In commenting on it, JH discusses at some length the doctrine of phlogiston as it relates to the discovery of the composition of water.
Received his note this morning, the first tidings he had heard of the matter. Gives his own opinion of the matter. Would have liked to have conferred with him. His neighbors are away so has been unable to consult them.
Further about the map printing problem [see FB's 1841-4-6].
Invites FB and his sister for a visit to Collingwood, where FB and JH can most easily complete the work of charting the southern stars.
Describes his view of the Great Comet of 1843.
Was unable to visit FB; JH is suggesting some options for FB dealing with the star map, and whether it needs to go to the B.A.A.S. for approval.
Sends along Frederik Kaiser's observations of Halley's Comet; [Robert] Everest is upset with JH because JH had signed a letter of support for a grant for T. B. Jervis.
Apologizes for having questioned GA's proposal [see GA's 1848-5-6], which is very good and should work well.
Asks RM to forward letter [see JH's 1844-7-22] immediately to G. B. Airy.
Indicates travel plans, including a visit to FB, with a side trip for business to Slough. JH comments on some astronomical observations he has received.
Very upset at an attack launched against JH in a manner that denigrates JH's father, William Herschel, in the process.
Looks forward to the possibility of a visit from RJ.
A long statement against a very nasty article in the Mechanics Magazine on the priority controversy surrounding the discovery of Neptune.
Family news, questions of son Willy's position, frost in the garden, and JH met Louis Philippe.
Thanks GS for a number of his papers on railway bridge fractures, gravitation, and the spectrum.
