The Radcliffe Trustees are asking for assistance in naming a new director of the Oxford Observatory; JH sends a draft response.
Draft of letter to be sent to Radcliffe Trustees, now being sent to G. B. Airy for his information [see JH's 1859-6-11].
Unable to attend the most recent meeting of the Society of Arts, where the idea of having a fixed musical pitch was discussed. As a committee has been struck to study this, JH sends in his thoughts on the topic.
Discusses the issue [then under debate] of a fixed musical pitch, urging that C be fixed at 512 vibrations per second and explaining in detail his reasons.
Returns GA's letter copy [see GA's 1859-6-14] with thanks, noting it is more complete than JH's own.
