Reading edition
The new system of electric signals has again altered the position of Bombay, which is placed now in E. long. (G.) 72° 48′ 4″. Before that invention the difference between London and Paris varied from 2° 20′ 15″ to 2° 20′ 24″. In 1854 M. Le Verrier determined it from 200 observations to be 2° 20′ 9.45″.
