Dear Tyndall
Thanks for Hirst’s letter,1 you shall have it back in a day or two; it will do me good to read it over and over again, so don’t be angry at my not returning it at once. By all means let him send Poinsot;2 his other requests shall also be attended to.
I send a duplicate proof of Ball’s paper;3 a proof has been forwarded by this evening’s post to Dublin. I have not yet read it but have glanced at it, and like it much
Yours sincerely | William Francis

Hirst’s letter: letter missing.
Poinsot: presumably a paper by Louis Poinsot. Hirst often relied on Tyndall to supply him with recent issues of journals and scientific papers of interest while he lived on the Continent.
Ball’s paper: J. Ball, ‘Observations upon the Structure of Glaciers’, Phil. Mag., 14 (1857), pp. 481–504.
