Asks JH's opinion about GA's plan not to print a separate volume of magnetic and meteorological observations for 1848.
Will reconsider the proposal about printing observations [see JH's 1849-3-29], and get back to JH.
Has little advice to offer JH about time calculation [see JH's 1849-3-29], except for fairly standard reminders.
Regarding the 'chilled' casting of a telescope.
Tells GA about the internal counterpoise system in use in some German telescope mountings, and includes a diagram; JH knows nothing about chilling speculum metal [see GA's 1849-3-7].
Some concerns about GA's intent of attaching magnetic and meteorological observations to the R.A.S.'s Astronomical Observations [see GA's 1849-3-28].
Asks GA if he knows of any rules or pitfalls in calculating time from earlier times [even B.C.] to the present.
