Regarding the publication of the magnetical and meteorological observations. Wonders if a letter from JH to the appropriate bodies would prove useful. Will give early consideration to the plan.

Took the chair at a meeting of the Committee for Physics at the R.S.L. Is to bring the matter before Council, who in turn will request the Master of Ordnance to publish the observations. Material from each observatory will require about half of a quarto volume.

Forwards papers relating to the Aden Observatory; please return, with any comments, to Col. W. H. Sykes. Submits suggestions for monthly information and comments on various topics.

Having heard that HP had expressed pleasure at some of JH's colored photographs, JH sends some more recent ones.

JH must have read William Whewell's History of the Inductive Sciences. John Murray thinks JH's opinion of this work would form a valuable article for the Quarterly Review.

John Murray transmitted JH's note regarding his review of William Whewell's book. Wonders if this letter has been acknowledged. Would like the paper as soon as possible.

Wishes he had communicated direct with JH regarding his article on William Whewell's History of the Inductive Sciences. Could not put it in the present number, but if any part of the article has been written please send it to their printer.

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.

A series of 'resolutions to be proposed as fundamental principles for a reform of the Southern constellations.'

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.

Has not had time to work on the constellations paper because of interference due to tithe surveys and land re-assessments, which JH fears may involve a lawsuit.

Is sorry JH did not inform him of the paper he was to read on the astronomical influence on climate. Would like an abstract when published. Would also like a copy of the verses on the great telescope. Encloses a paper of his own.

Father has died and he has taken over the business. Would like references as to where he can find information on instruments.

Has received no reply to his previous letters so probably gave an incorrect address.
