States unequivocally that the letter referred to in JS's 1864-10-11 has not 'a syllable' that can in any way affect the question of the conduct or character of the late Humphry Davy. JH could not conceive of publication of the letter without the express consent of the other person mentioned in it [Charles Babbage].

As JH has been approached by Charles Babbage for permission to publish certain portions of JH's correspondence, JH is writing to say that he gives both Babbage and JS permission to publish what they will.

Writes a very kind letter, encouraging JS to remember the good days when JS and JH worked together in astronomy, and to forget less happy events. [This letter was enclosed in JH's 1865-5-31 to John F. South.]
