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.

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.

Work will begin on obelisk at Feldhausen. Occultation of Gamma1 and Gamma2 Virginis observed. Triangulation survey will take TM away from Royal Observatory for extended time. Slave ship carries small pox and causes outbreak. Parallax observations show brightest stars, not nearest.

Acknowledges letter requesting land for the Magnetic Observatory. Has a portion of land available in the S.E. corner of the grounds, but it will be necessary to obtain the permission of Rear Admiral George Elliot.

Erebus and Terror have arrived in Simon's Bay. Discussed Magnetic Observatory with J. C. Ross, Captain Croper, and F. E. Wilmot, and wrote government requesting funds. Obelisk has not yet reached the Cape. Small pox rages in Cape Town.

Arrived in Zwartland in September. Surveyed grounds; measured baselines. Will be absent from observatory until Zwartland work finished.

Informs JH that the B.A.A.S. has placed him on a committee to provide two actinometers for observing high in the Alps.

Informs JH that the B.A.A.S. has placed him on a committee to study the possibility of using balloon ascents to study the upper atmosphere.

Informs JH that the B.A.A.S. has again placed him on the committee to supervise the translation and publication of foreign scientific memoirs.

Sending check and a note from the editor of the Quarterly Review.

Has forwarded JH's note regarding a review of William Whewell's book to J. G. Lockhart, who will be very pleased to receive such an article.

Sending a list of the principal instruments possessed by Lt. Col. George Everest. Also the last report made by Everest of his observations.

Apologizes for his long silence. Outlines recent events at the Cape concerning Andries Stockenström, who has been replaced by J. Hare, and Major C. C. Michell, who has resigned. J. R. Innes has been all over the Colony and will shortly be coming to England. F. M. Eardley-Wilmot has dined with the Napiers.
