Proposes meeting times in town. Suggests that JF observe the upcoming total eclipse astronomically. Agrees with JF's seemingly 'cold &c' circular on scientific partnerships, while regretting that it needed to be written.
Some information about Charles Piazzi Smyth. JH needs information about some of RH's photographic paper, which JH has tried but without success.
Sets up approximate meeting time, depending on his family's timely departure to Antwerp, with JF at the R.S.L. apartments.
Thanks for assistance in preparing trip. JH's daughters will probably not stay in Brussels long. Mentions his first engraving for Cape observations of nebulae is to be engraved this very day. Three quarters of his reductions of the southern sweeps are completed.
Thanks WS for C. P. Smyth drawings of Cape monument and Gamma Virginis observations. Notes J. H. Mädler's work on double stars and the doubt that they obey the inverse square law. Discusses use of photography in astronomy.
