|Copy letter from Robert William Frederick Harrison, to J E Cullum, Valencia Observatory, Cahirciveen, County Kerry, Ireland
|9 March 1901
|The late Professor Fitzgerald was in communication with the Royal Society about publishing the reductions of Cullum's Magnetic Observations. The Royal Society is unable to form a definite opinion without more particulars. Asks Cullum to send the dates, hours and results of the individual observations of declination, inclination, and horizontal forces that he sent to Fitzgerald.
