GEOGRAPHICAL POSITIONS.

JAMAICA, ETC. 



NOTES. 



1. Cape Matsi. — Captain Foster placed Cape Maysi in 74° 5' 18", considering Chagres 

 as 78° 57' 19". Captain Owen made it 74° 8' 0". 



2. Sx. Iago db Cuba. — Mr. NichoUs, Master of the Shearwater brig of war, in 1819, 

 communicated the situation of the Morro Castle of St. Iago, from observations made in 

 that ship, as follows : — Latitude observed, 19° 57' 50" ; longitude by lunars, 76° 2' 45 ; 

 by chronometer, 76° 0'. The Spanish Chart of the harbour represented the Morro as in 

 75° 55' 83" W. Telegraphic determination from Havana, by United States Officers, in 

 1875, placed the Morro Lighthouse m long. 75° 52' 6" W. 



3. Cape Antonio, Isle of Pines, «fec. — On the 12th of August, 1817, Capt. Livingstone 

 came to an anchor off Cape Antonio, in 7 fathoms; and, by an excellent observation, 

 found his latitude to be 21° 53' 54", confirming that given by the Spanish Officers. The 

 longitude was considered as well estabUshed between 84° 57' and 84° 58'. The Baron 

 von Humboldt gave 84° 57' ; Captain Owen, 84° 58' ; the Spanish Officers had pre- 

 viously given it as 84° 57' 30". The position given in the Table accords with that on the 

 most recent charts. 



4. Havana and Lighthouse. — The longitudes in the western part of the Caribbean 

 Sea depend upon the position of the Morro Lighthouse, Havana, given by Don Jose 

 Joaquin de Ferrer, Astro. Soc. Mem. iv., page 586 ; long. 82° 22' 12" W. Note : Telegra- 

 phic determination from Washington, United States, by the United States Hydi'ographic 

 Office in 1875, placed Morro Lighthouse in long. 82° 21' 23" W. 



The position of the Engineer's post, near the steam wharf under fort No. 4, Havana 

 Harbour, has been deduced from the Morro Lighthouse, and is here given as being 

 convenient for rating chronometers, lat. 23° 8' 53" N., long. 82° 20' 48" W. 



The position formerly given was lat. 23° 8' 18" N., long. 82° 22' 4" W., the longitude 

 being the mean of twenty results from stars eclipsed by the moon, by Don Josef Joachim 

 de Ferrer, 1809-10-11-12. This place, which was taken by Lieut. Raper as a secondary 

 meridian, was considered by him as in long. 82° 21' 57" W. The difference, 17", between 

 this and Mr. Purdy's position, as given in our previous editions, is but trifling, and the 

 difference between Mr. Purdy's position in 1850 and that determined electrically from 

 Washington in 1875, is but 17", the latter position placing it in 82° 21' 23". 



5. JAMAICA in general. — In his " Outline of Jamaica, 1821," Mr. De Mayne gives 

 Morant, or the eastern point, in longitude 76° 12', and South Negril, or the western 

 point, in 78° 25' W. Mr. Leard, in his survey of 1791, gave Morant Point m 76° 3', and 

 South Negril in 78° 33' ; consequently, he represented the island more than 15' longer 

 than it has since been exhibited.
