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.
