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.'
Advice as to best way to present JL's method of calculating the orbits of comets to R.A.S. If JL desires R.A.S. to undertake calculations, might be some difficulty.
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.
Asks whether JL wishes to present method [see JH's 1847-12-4] at next R.A.S. meeting.
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.
Placed JH's letter before the Committee of Papers but the Committee did not change its views regarding the publication of W. H. F. Talbot's paper. Is pleased JH is promoting his experiments so successfully.
J. F. Daniell informs JL that the table was calculated by William Galbraith. James Apjohn states everyone is in agreement that the absolute heat of steam is constant, but JL disagrees. Intends raising the matter of John Southern's experiments at the next meeting of the B.A.A.S.
Obliged by JH's letter. Would he let him know what he thinks of raising the matter of repeating John Southern's experiments. His own eldest son has gone to Langley; he shows little aptitude for figures but a decided turn for Natural History.
Will find the reference to S. D. Poisson in his own paper on the Heat of Vapours. The subject is in a state of confusion. John Southern's experiments are detailed in John Robison's Mechanical Philosophy, which can be sent from the R.S.L. library if JH does not possess it already.
Much obliged for JH calling but regrets he was out. The question [on steam] they have been discussing seems to be answered by a paper by a Prof. Karl Holtzmann he has just come across; comments on this. If JH is coming to S. J. A. Compton's (2nd Marquis of Northampton) soiree will he come and dine at St. James' Place?
