NOTES. 



1. Porto Praya. — The longitude of this place appears to be well determined, particular 

 attention having been directed to it by many of our most skilful navigators. Captain 

 FitzEoy placed the West point or landing-place on Quail Island (called also Gun Point"), 

 at Porto Praya, in longitude 23° 30' 0" W. Captam P, P. King made it 23° 80' 17" ; 

 Captain Vidal, 23° 31' 28" ; and Captain Owen, 23° 31' 3" ; therefore, 23° 30' 34", the 

 longitude formerly assigned to it by Mr. Pvu-dy, in previous editions of this work, cannot 

 be far from the truth. Telegraphic observations by MM. de Sugny and Garnier, 1885, 

 place the flagstaff on Quail Island as 6° 4' 49-6" West of Dakar East jetty, which would 

 make it 23° 30' 17" West of Greenwich. 



2. St. Vincent. — The position of the flagstaff in front of the Brasilian Submarine 

 Telegraph Company's Office was determined, by telegraphic means, by United States 

 ofiScers, in 1878 and 1879, in eormection with the establishment of secondary meridians 

 on the East Coast of South America, to be in long. 24° 59' 22-3" W., or about 1' 50" 

 eastward of the position previously given. The latitude is 16° 53' 20*12" N. 



3. Captain King made Terrafal Bay, at the S.W. end, by eleven chronometers, in 

 longitude 25° 20' 1" ; Captaui Owen made it 26° 21' 42" ; and Captain Foster, 25° 22' 56" 

 the mean from these being about 25° 21' 30" ; and the West point, 25° 23' 10". 



The Variation of the Compass is increasing among the Cape Verde Islands, at the rata 

 of about 1' per annum.
