Questions related to JH's 1846-9-26 having been asked by RR, JH writes to answer these questions.
Is applying for the French Mastership at the Belfast Academy and would be pleased to receive a testimonial from JH. Is also inviting subscribers for a new work to be published later.
A long statement against a very nasty article in the Mechanics Magazine on the priority controversy surrounding the discovery of Neptune.
Has been carrying out a series of experiments with spiders immersed in acids and finds their bodies are not protected in any way. Has also been experimenting with elastic tissues to see if there is a change of temperature.
Has seen the seventh satellite of Saturn. Encloses diagrams and comments on them.
Was in error when in his last letter he stated he had seen the seventh satellite of Saturn; he has yet to see it.
Details of WL's observations of the seventh satellite of Saturn.
Details of WL's observations of a ring and satellite of U. J. J. Leverrier's planet.
François Arago has communicated JH's letter informing him that UL has been awarded the Copley Medal.
Will put the matter of UL's medal into the hands of Edward Sabine, the Foreign Secretary, who will hand it to the Ambassador for delivery to France.
Is pleased with the arrangements for the forwarding of his medal. Is sending for the R.S.L. five examples of his researches.
Did not realize his question would require so much of JH's valuable time to answer. Hopes to introduce some safe German Philosophy into the appropriate departments at Trinity College. Will look into the Lehrbuch.
Received his letter enclosing Edward Sabine's a few days ago on returning home. Busy at College; otherwise would have written. Could have attended a meeting of Committee of Physics had he known. Discovery of the new planet is a triumph. Has he heard of the attempt to destroy the telescope of William Parsons (3rd Earl of Rosse)?
When he received JH's request to give a lecture on American geology he did not treat it seriously. Now R. I. Murchison has made a similar request so thinks he could work up a popular lecture on the Mississippi Delta. Will keep off his old ground.
H. C. Oerstedt has been elected to the Society to replace F. W. Bessel, who has died. The Society is lacking one part of the Memoirs of the R.A.S.
Comments on WL's observation of the seventh satellite of Saturn as noted in WL's 1846-8-26.
Believes that the observations WL has made are quite sufficient to establish the existence of the seventh satellite of Saturn.
Announces, to WL, the discovery of a new planet beyond Uranus, gives co-ordinates, and urges WL to look for satellites 'with all possible expedition.'
Has just received his remarkable paper on the dynamical theory of crystalline reflection and refraction. Comments on this. The subject has not lately occupied his attention. Would like clarification on some points.
Has been on the Continent, which accounts for the delay replying to JH's letter of June. Regrets he cannot give an answer to JH's queries regarding the constitution of the ether. Fears his hypothesis on the density of the ether is not clear as it has misled JH. Has read Michael Faraday's papers with eagerness.
