Their letters have missed more than once, and JH's last letter is now at the Return Office. Would like to see this letter to learn JH's views on the article on Heat. Gives own ideas how article should be written, too busy himself, so hopes JH can write it, or does he know any other person?
Apologizes for delay in writing. Describes JH's travels across Europe back to England. Is sending GP copies of JH's papers in physics, mathematics, and astronomy, especially double stars. Describes a new instrument, a floating collimator, described by Henry Kater at the R.S.L. [Rough notes for a later letter on the back of part of this one.]
Thanking him for his friendly reception when in Italy. Is sending GA journals and pamphlets likely to be of interest to him. Regarding various papers on the electrization of mercury. Please send details of Giuseppe Bianchi's barometer.
