Asks for details of several actinometers.
Surprised that JB sees theological doctrines in JH's astronomical observations.
Sends £5 note. This is all he can spare. Has no recollection of ever meeting him and their relationship is very remote. Wishes a speedy improvement in his prospects.
Thanking him for his letter in answer to hers on theological doctrine and its relation to JH's observations.
Reports on and recommends for publication experiments in paper [see RSPT, 137 (1847), 253-] by [A. F. J.] Claudet on effect of solar radiation on silver plate's mercury deposit, but questions conclusion about triplicity of photographic action.
JH has arranged for U. J. J. Leverrier, J. C. Adams, and Wilhelm Struve to visit JH together at Collingwood. JH is writing to invite JL to join them.
Tells JH that his invitation to visit came too late. Regrets deeply not having the opportunity to meet, but expects to do so next year. Hopes to present two works to JH at that time. Mentions working with the talented P. L. Seidel, his assistant.
Tells JH of [P. L. von] Seidel's success in comparing luminosity of stars by means of a photometer. The results match those of JH. Sends JH a copy requesting that the form be ignored and it be communicated to the R.A.S.
A resolution passed by members of the B.A.A.S. meeting at Oxford urges the publication of William Herschel's papers in one volume.
Asks RS to check the background of Samuel B. Lamb, who wants to lease JH's house at Slough.
Will send his man to C. R. Weld. F. W. Bessel will be in good time for council. Is glad he is on the last chapter.
Responds to JH's request [1847-6-28] that RS inquire about Samuel B. Lamb. Has visited [W. R.] Dawes and his telescope; thinks he will be productive. Lefevre [George Shaw-Lefevre?] has started for the university, adding 'what chance he has of success I can't guess.' On JH's contacts with Cambridge University.
Is still working on the obituary of F. W. Bessel; JH will not be at the R.A.S. anniversary dinner; comments on the usage of various fixed points for producing standard thermometers.
As instructed, sent 14 copies of JH's book to James Hayday, bookbinder. Confirms style of binding, lettering, and folding of plates requested by JH. One hundred copies will be finished by end of week.
Has not yet received copies [of JH's Cape Results] from Smith, Elder & Co. [Algernon Percy,] Duke of Northumberland called to discuss binding but made no decisions. Awaiting JH's instructions by return post.
Replying to GP's 1847-6-28, is worried about the amount of time that will be required of JH in preparing a suitable biography; does not want it to interfere with other work on hand.
