Sends photograph of a medal lately struck in Paris to commemorate the discovery of 100 asteroids, on which Hind appears.

His last note on the Julian period puzzled him. Has not taken many double star measurements, but will send on a few later. Has not finished the ecliptical charts yet. Regarding a planet more distant than Neptune.

Would like his views on an actinometrical scheme. Has been busy over the affairs of the late Sir James C. Ross.

Is grateful for JH's notice of his ideas. Outlines his ideas for an actinometer.

Finds there is not one of JH's actinometers at Kew; would be grateful if he could inform him who has been working with one.

Thanks for the information. Has written to Henry Barrow, and to Negretti and Zambra. The latter can supply actinometers for 14 guineas; too expensive for him. Barrow has just replied that he can supply for 6 guineas.

Tried Kew and the Admiralty for actinometers but had to obtain one from Henry Barrow in the end, which was broken en route. Thinks these are too fragile for mountain climbing.

Is grateful for JH's reply. Gives reasons why he was looking for smaller and more portable instruments to take with him to the Alps.

Has now applied to the R.S.L. for a Government Grant and would like JH's support for his application. Wishes sunfall as well as rainfall was recorded.

Found it impossible to answer JH's letter before his departure. Delighted with JH's contrivance. Hopes to make some observations on Mont Blanc.

Has been voted a grant of £30 from the R.S.L. Committee. Results of his recent observations in the Alps. Comments on these and gives indexes for instruments.

Sir Henry James does not wish to be connected with the new expedition to Sinai until the work of the previous one has been cleared. Will approach the Royal Geographical Society with his scheme. [H. S.] Palmer is the man to go on this expedition.

R. I. Murchison has forwarded JH's letter about the noises at Nakkus in Sinai. Has heard the noises several times and thinks they are caused by the movement of sand. There is much static electricity in sand.

Had no time to write before he sailed [see FH's 1868-10-23, which is similar in content]; forward letters to the Ordnance Office, Southampton.

Sinai expedition did not complete its work. Would like to send out Messrs. E. H. Palmer and C. F. T. Drake again. Can they continue to use JH's name as a trustee?

Takes it that the expense of the Sinai Expedition so far carried out has been met from the funds. Sees no objections to a continuation of the expedition.

JH's translation of first canto of Dante's Inferno (1868) is best HH has ever seen. Thanks for JH's commendation of HH's own translations [?]. More observations of soap bubbles.

Received manuscript of JH's translation of third book of Iliad.

Received JH's translation of fourth book of Iliad. Will return it with comments in a few days. Attended two or three excellent lectures by JH's son. HH needs to balance mental efforts with more physical activity.

Will send copy of second edition of HH's Essays on Scientific...Subjects (1862). Received letter from HH's friend and former patient Louis Napoleon, who will send copy of Napoleon's book on Gallic campaigns of Caesar.
