Is returning the proof of [Stephen] Groombridge's catalogue. Comments on the expense of printing it. Is pleased that Thomas Henderson has been appointed Cape Astronomer.
His paper on double stars is required for press so would be grateful if it could be sent along. The society is short of papers for reading so any JH can produce would be very welcome.
Sends JH's observations and measurements made during JH's Sept. 1821 ascent of a peak near Mt. Rosa. Also sends JH's observations of Mt. Etna made in June 1824.
Is grateful for the copies of his notes on his observations. Has compared them with his own and found them remarkably similar. JH should see Mr. Hildyard of Eton if he wishes to compare notes on their expeditions. Regarding JH's measurement of Etna.
Comments on some of JH's geological papers. Has received a paper on Yorkshire geology from R. I. Murchison.
