Unpublished letter, 'On the determination of the difference of longitude by means of the magnetic telegraph' from Elias Loomis to [Edward] Sabine
Reference number: AP/31/9
Date: 08 August 1848
Description
Loomis describes a series of experiments made under the direction of Professor Bache, for the determination of the difference of longitude between New York, Philadelphia and Washington, by means of the magnetic telegraph. By this series of experiments he considers it established that, by means of Morse’s telegraph, two clocks distant from each other 200 miles, can be compared together with the same precision as if they were placed side by side; and that the difference of longitude of two places can be determined with the same precision as the relative error of the clocks. He describes further similar experiments.
