R.S.L. business about an observatory at the North Cape in Sweden.
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.
Believes that R.S.L.'s request for £3000 grant to establish permanent magnetic and meteorological observatory is too hasty. Urges caution. Points out potential problems.
Thanks for 'small, but intense' volume sent.
Is displeased by R.S.L. Council's seemingly rash resolution with regard to idea of permanent magnetic observatory.
Thanks for letting JH know about honor accorded at 'the Anniversary' [Meeting]. Offers condolences on JL's 'late severe loss.'
In light of minutes of R.S.L. Council meeting, outlines vision of permanent national physical observatory and, more importantly, an experimental institute or college. Hopes Edward Sabine will be interested.
Comments on several different reports; also on some experiments that lead JH to think much of the radiant energy of the Sun is absorbed in the atmosphere.
On the 'misfortunes & mishaps' of the Aden magnetic observatory and on the proper care of magnetical instruments.
Has read over all JH's report. Makes suggestions for alterations and omissions to bring it into line with the wishes of Council.
Sends a copy of his work on the tides. S. D. Poisson's theory is noticed near the end of the 2nd volume of Mécanique. Thinks some experiments are necessary to find the effect of the sun on climate. Has received a note from the Treasury.
Would like JH to amalgamate William Whewell's and JL's memoirs. Thought the principle of universal gravitation was conceded by all. Treasury have sent back the bills and want the Antarctic ones separated from the Observatories ones. Should take notice of the effect of iron steams [on instruments?].
Sends a copy of the report, which he has looked over with P. M. Roget. S. H. Christie seems averse to altering it. Thinks it important to make observations of the temperature with barometric readings in balloon ascents. Only readings by J. L. Gay-Lussac at present.
Has received letter and report. Will he consider by Thursday whether to refer the report back to the Committee. Does not think the balloons should be too large. Regarding the sun's effect on climate. Presumes Council cannot alter report.
Regrets that JH in his address to the R.A.S. should have omitted to mention the names of P. G. le D. Pontecoulant and JL in connection with the calculation of the lunar and planetary perturbations.
Thanks for his letter. Will communicate to P. G. le D. Pontecoulant what JH has to say about him. It was certainly unwelcome that JH should omit JL's name when referring to the lunar theory.
Sent an extract of JH's letter to P. G. le D. Pontecoulant. Now gives an extract from Pontecoulant's reply. Is sorry they are not to see JH at S. J. A. Compton's (2nd Marquis of Northampton) tonight.
Council passed 'with great unanimity' resolutions regarding permanent magnetic observatory to be established in London.
Further remarks on council meeting about permanent magnetic observatory and G. B. Airy's answer [to invitation to head it?]. Awaits communication from William Lamb (Lord Melbourne).
