Copy of draft letter, from Sir John Herschel to Humphrey Lloyd, dated at Slough Copy of draft letter, copied as part of the correspondence project led by Colonel John Herschel FRS following the death of his father. Would like a statement from Edward Sabine and Humphrey Lloyd outlining the probable expense and materials required for the proposed expedition so that he can hand it to the government at the interview. Has written to G. B. Airy, who is not in favor of the proposed expedition, so will write again. Thinks it necessary for men of science to agree before presenting petitions to the government. 16 November 1838
