|Copy letter from Francis Alexander Towle, Assistant Secretary of the Royal Society; to the Superintendent of Mining; His Majesty's Gunwharf, Portsmouth
|19 September 1921
|Informs the Superintendent that the instruments mentioned in his letter of September 13th are the property of the Society and asks that arrangements be made to send them back. Notes that he can offer little information as regards the magnetic balance; all he knows is that Mr. Walker sent it to Dr. Schmidt for testing and later made an unsuccessful attempt to have it returned.
