DIFFERENCE IN TIME
IN THE PRINCIPAL CITIES OF THE WORLD.
Variation of time depends on Longitude; East of Greenwich every degree causes the clock to be 4 minutes earlier, every degree West 4 minutes later.
The times stated in the above diagram are strictly correct according to longitudinal difference, but it may be well to explain that the Railway Companies on the Continent largely adopt either MidEuropean or East European time. The following shows more precisely what this means:
BELGIUM AND HOLLAND.-Greenwich (West European) time.
FRANCE.-Paris time-9 minutes 20'6 seconds earlier than Greenwich.
AUSTRIA, DENMARK, GERMANY, ITALY, SWITZERLAND, NORWAY, SWEDEN.-Mid-European time 1 hour earlier than Greenwich. Italian time is reckoned from 1 to 24 o'clock.
GREECE. Athens time-1 hour 35 minutes earlier than Greenwich.
BULGARIA, ROUMANIA AND EASTERN TURKEY.-East European time-2 hours earlier than Greenwich. RUSSIA. St. Petersburg time-2 hours 1 minute earlier than Greenwich. Moscow time-2 hours 30 minutes earlier.
SPAIN.-Madrid time-14 minutes later than Greenwich,
PORTUGAL.-Lisbon tiine-364 minutes later than Greenwich.

In the 1-in. maps a number of symbols are used: these are explained below, as well as the manner in which roads, railways, tramways, &c., are indicated.
ALTITUDES in the Ordnance Survey maps are those above the approximate mean sea level at Liverpool. For Ireland they are given in feet above low water of spring tides in Dublin Bay.
CONTOURS begin as a rule at the 50-ft. line above mean sea level. They only appear on the 6-in. and 1-in. maps and are shown at intervals of rco ft. up to 1,000 ft. The 6-in. maps of the mountainous parts of Scotland are not contoured, but contours sketched by water level are shown at 100 ft. and 250 ft. intervals on the 1-in. maps.; In Ireland only a few counties in the north are contoured.
