Papers on determining galvanic longitudes, 1852 - 1854
File
Reference Code: GBR/0180/RGO 6/633
Scope and Contents
Correspondence and papers concerning the use galvanic signals to determine longitude. The papers describe the attempts to establish the longitude of the Edinburgh, Oxford and Cambridge Observatories by observing set stars and taking the difference between the local time and the Greenwich Time received by telegraphic signal. Other centres included in the project, but not necessarily tested, were Liverpool, Dublin, Vienna, Bristol and Lowestoft. The papers include correspondence with C.P....
