Response to some papers sent to R.A.S.
On the observation of sun spots.
More on the construction of a good optical eyepiece for solar observations [see FH's 1864-4-27].
Would like FH to study a phenomenon that JH has noticed on the sun's disk and that has no connections with sun-spots.
Proposes to travel to visit FH next day to observe the sun with him.
Details about sunspot observations.
Returns a paper of Mr. Stobart, which deals with astronomical knowledge of the early Egyptians.
