Provides examples to justify governmental support of various magnetic and meteorological observations. States that 'Terrestrial magnetism ... of all sciences of observation holds out the greatest present prospect of decisive reduction under ... exact theory.' Mentions work by N. L. Lacaille and Thomas Maclear at the Cape.
Quotes passage from C. E. Trevelyan (Treasury Office) to [Hussey] Vivian concerning the number of copies of published data and the number of magnetic observatories. Requests JH's perusal and advice. Includes letter from [A. T.] Kupffer on latest observations.

Asks whether the R.S.L. should request government funding for Cape observations and experiments. Wonders if astronomical and magnetic observers there could assist each other. Requests information on the atmosphere.
Sends [James Clark] Ross's journal and revised B.A.A.S. magnetic report. Discusses proposals for observation in Africa. ES will send various instruments to Africa.
Speculation about land masses and climate in Arctic regions. Extols James Ross's talents. Discusses John Dalton's pension and who should be devoting efforts for approving pensions.
Discusses recent magnetic disturbances and their publication, as well as sending reports on them to G. B. Airy, Humphrey Lloyd, C. F. Gauss, and others.
