Thought his letter had miscarried. Thanks for the gift of his recently published work [Cape Results]. Will be glad to supply any information from his own work on comets, which he hopes to send in the course of a few days. Is studying U. J. J. Leverrier's method of development by elimination.
Francis Beaufort is on leave. Does JH know of Beaufort's intentions regarding instruments assigned to [William] Mann, who departs aboard Arab in two days?
R.S.L. policy for paying postage on scientific communication by members to and from foreign correspondents. Addresses of proposed recipients for Cape Results. ES's illness and problem with eyes.
In Francis Beaufort's absence, AM is trying to clarify the matter of an astronomical instrument, apparently obtained from George Merz & Son.
WH notes that quaternions derive some interesting results in problems with three moving bodies.
Unable to explain how [Robert] Phelps received copy [of JH's Cape Results]. His name not on any list, and printer Peter Stewart did not send him one. Stewart requests copies be sent to John Ruskin and James Thomson. Will carry out JH's instructions for copy to Wilhelm Struve.
Thanks for excellent Talbotypes. Notes how few photographs are 'perspective representations on a vertical plane' and suggests how to correct this.
