Urges doubling number of lunar observations.

Has received JL's memoir on the tides. JH would like to amalgamate certain portions with a memoir from William Whewell. JH adds some comments on photographic experiments he has made.

Has just received his remarkable paper on the dynamical theory of crystalline reflection and refraction. Comments on this. The subject has not lately occupied his attention. Would like clarification on some points.

Arranging a meeting of the Magnetic Committee to set the agenda for the magnetic conference to be held during the B.A.A.S. meetings in Cambridge.

Responds to CS's [see CS's 1847-7-14] request for observations of Gamma Scorpii as a double star. JH comments on CS having omitted J. C. Adams from the list of Neptune discoverers.

Comments on proofs of WW's German translations. JH recommends that the magnetic observations already made should be reduced to show some results, rather than adding more observations.

Comments on WW's publication on education [Liberal Education, 1845 ?], especially as it applies to the teaching of mathematics. JH has been teaching JH's son William mechanics by WW's book on the subject.

No news yet about the request to Robert Peel for money for magnetic observations.

States the case for the accuracy of the observations and reports of the discoveries of the sixth and seventh satellites of Saturn made by JH's father, William. [This letter seems to be tied to JH's 1844-7-22 in terms of date of writing.]

Encloses star observations. Comments on his instrumental system. Cannot find the rule for position when two stars are of equal magnitude. Neptune with the convicts is anchored in Simon's Bay, awaiting the answer from H. G. Grey (3rd Earl Grey).

How does one jog the memory of the First Lord of the Treasury [see GA's 1845-10-3]?

Is gratified that JM is taking an interest in double stars. Comments on some of the observations and time of their orbits.

Is very critical of a series of three foreign memoirs that JH believes certainly should not be published. Concludes with a strange postscript on catalepsy.

Will do all in his power to ensure that MM receives copies of the publications relating to the Fixed Observatories. Does not think MM could have seen a copy of JH's paper on photographic action when he wrote the notice in Annales de chimie. Comments on this paper and more recent experiments in this field.

Giving reasons why he would not like his name put forward as a magistrate.

Do as JM suggests. Further comments on JH's dispute with the theories of Auguste Comte.

Tells GA about the internal counterpoise system in use in some German telescope mountings, and includes a diagram; JH knows nothing about chilling speculum metal [see GA's 1849-3-7].

S. J. A. Compton [Lord Northampton] has addressed a private letter to Robert Peel [see GA's 1845-10-9].

Is anxious about his aunt Caroline Herschel and would like news of her health.

AS JH understands the matter [see GG's 1845-12-23], GG is the only knowledgeable member of the committee, and so it will be up to GG to present information and propose some means of moving ahead. JH makes some critical remarks about the nature of B.A.A.S. committees.
