NOTES. 



1. Greenwich Observatory, the Prime Meridian. — This Observatory was founded 

 during the reign of Charles II., and the Prime Meridian in general use passes through its 

 great transit instrument. In 1884, a Conference of delegates, appointed by twenty-five 

 European and American coimtries, assembled at Washington, in the United States, for 

 the purpose of fixing a universal Prime Meridian, to do away with the inconvenience 

 experienced from various countries each assvuiiing a meridian of its own. Twenty -two 

 delegates voted in favour of Greenwich ; San Domingo voted in the negative ; whUe 

 Brasil and France abstained from voting, the latter favouring a so-called " neutral " 

 meridian, to pass through the Azores or Behring Strait. The Geodetic Conference held 

 at Rome, in 1883, also very decisively expressed its opinion in favour of Greenwich. 



French charts adopt the meridian of Paris ; Spain adopts the meridian of San 

 Fernando, Cadiz ; and Portugal that of Lisbon. Most other nations use the meridian 

 of Greenwich. 



From 720 observations of the Pole Star, made during eighteen months of 1825 and 

 1826, the latitude of the Royal Observatory was deduced as 51° 28' 38". By a later 

 correction it was placed in 51° 28' 40'16"; but by the Grand Trigonometrical Sr.ive3' it is 

 taken as 51° 28' 38-80". 



2. Plymouth Breakwater. — On the northern side, near the centre, is a landing pier, 

 on the East end of which is a granite pillar, with a brass plate, on which is engraved its 

 rorrect latitude and longitude, 50° 19' 59" N., 4° 8' 52" W.
