whose longitude is west of Greenwich, to the time of sunrise or sunset add the longi tade in time, and to places whose longitude is east of Greenwich, subtract the longitude in time, the result will be the railway or Greenwich time that the sun rises or sets. The same rule is applicable to places in Ireland whose longitude is east or west of Dublin. N.B.-Longitude in arc, indicated by the signs" (degrees, minutes, and seconds) is converted into longitude in time by reckoning 360° = 24 h., 15° = 1 h., and 1° = 4 m. Example:- On June 21st at Penzance, in latitude 50° 7' N. and longitude 5° 31′ W., what will be tlae railway time that the sun rises and sets? Sun rises. h. m.

For example:-On the 10th of January, the morning High Water at London Bridge is 8h. 10m.; the High Water at Dover Harbour is 2h. 55m. earlier; subtract, according to the direction, 2h. 55m. from 8h. 10m., and the time of High Water a Dover Harbour on that day will be found to be at 5h. 15m. in the morning.
