Regrets missing JH's visit. Refers JH to [Charles] König for admission to Department of Natural History at the British Museum.
Many thanks for his beautiful ballad.
JH is correct, and TY's 'little man is wrong.' Moon's apparent angular motion increases as spectator moves closer.
Packets will be sent Saturday by Smith, Elder & Co., so that the one for [Caroline] Herschel will not be late for Mr. Köhler.
Regrets delay in answering JH's communication, but was away from Bath when the letter arrived. Interested in the extraordinary local attraction observed by Mr. Duncan in 1791. Gives locations of three such situations in his recent voyage. Comments on the use of Peter Barlow's plate. Will write to Barlow before his next voyage.
Will forward Astronomische Nachrichten to JH and Astronomical Society. Comments on quality of [Joseph] Fraunhofer's micrometer, which has only the wires illuminated. [C. F.] Gauss uses a theodolite to determine the angle of the telescope.
Requesting information of the dispersion of rays in Crown and Flint glass.
Had no report he could offer the Astronomical Society. Outlines the situation in Chile. Hopes to arrange the material on his recent voyages in the form of a book.
