Had written previously to JH to obtain more information about JH's father, William. Is now asking JH for a response to the same requests.

Thanks RW for sending RW's Mittheilungen and RW's Neue Untersuchungen. Replies to RW's queries about JH's ancestry and about the current state of JH's father's largest reflecting telescope.

Thanks JH for his letter, and RW sends on additional writings in astronomy.

Thanks RW for sending him a photograph of RW; sends photograph of JH in return.

Because RW has had no response from JH, he is worried that if the letter and printed material were not lost, then JH must be dissatisfied with what RW had written about JH's father, William.

Thanks RW for sending copies of RW's memoir on JH's father. States that JH has now revised a catalogue of all JH's father's double stars.
