A note to arrange a meeting with JH.
Would like JH to come to Manchester on 23-25 to give support for the Kew Observatory. F. W. Bessel and G. A. Erman are coming.
Thanks for suggestion of gold plating the telescope mirrors. Mentions idea of mounting a reflector horizontally but finds its execution 'insufferable'. Thanks for work on photometric measurement of light of stars. Disagrees on some results. Encloses new photographic specimens.
