Asks for JH's help in trying to determine the likely cost of making magnetic observations at Greenwich.
Thanks JH for his help [see JH's 1840-8-14], and tells JH about a visit to Greenwich by Charles Wheatstone.
The Royal Observatory wants to make magnetic observations at Greenwich, and it appears will need to make some building alterations. Estimates are required immediately by the Admiralty/Treasury, and GA seeks JH's assistance.
