Having been asked for copies of standards, it seems to JH that the Royal Mint is not the office to decide on such requests.

JH is very ill; would GA please deal with the disbursement of funds from Melbourne University [see JH's 1854-10-17].

A note of information about the impending forwarding of all Melbourne University materials to GA [see JH's 1855-3-23].

A letter of information, together with a list of all material, sent with the material, to GA [see JH's 1855-4-13].

A letter to accompany Frederick McCoy's 1855-3-9, indicating that it seems appropriate to pay the bills. One of the professors just appointed has died in Australia.

Has had a letter from Melbourne University, with instructions to transfer all the money to Melbourne's agent in London [see GA's 1855-5-30]; JH is slowly recovering.

Further instructions from Melbourne about the transfer of funds [see JH's 1855-7-8]; will be happy to get rid of this problem.

Encourages GA to make requests to ensure that the Royal Observatory instruments are first rate [see GA's 1855-10-24].

[Reply to GA's [1856-4-6 or earlier] on Mohamet's coffin theory.] Congratulations on GA's son winning a scholarship. JH's health is better, but he cannot walk yet.

A number of options are proposed by JH to help GA solve his problem with the mercury level [see GA's 1856-4-14]; JH is feeling much better but fears he may 'never again be able to walk.'

Has no actinometers available [see GA's 1856-4-23], but tells GA where he can get one; rhapsodizes about the beauty of nature around him, and the silliness of a person.

Some more information on the use of the actinometer [see JH's 1856-4-24 & GA's 1856-6-3]; some news of JH's wife, Margaret.

A note to accompany the forwarding of a communication to GA.

Expresses unease about P. S. Laplace's formulation of the barometric determination of height; in a postscript comments that Michael Faraday's lecture on conservation of force is a 'strange production.'

Suggests ways of eliminating transmission of vibration to a piece of sensitive equipment.

Asks GA for clarification of the value for the 'mean equatorial horizontal parallax' of the moon, since two different values are given by different authors.

Thanks GA for a letter of introduction to friends in Rome [used by JH's daughter Margaret Louisa and her new husband, Reginald Dyke Marshall]; JH is willing to serve on a committee with GA and others if he does not have to go to London for meetings.

Suggests GA alter some phraseology and tone in his response [see GA's 1858-5-4] to Edward Sabine's report on magnetic observatories.

Intends to set up a meeting with appropriate members of the B.A.A.S., in order to prepare presentation about magnetic observatories for the B.A.A.S. meetings in Leeds.

Responds to GA's 1858-6-25, and essentially agrees with GA's assessment.
