GEOGEAPHICAL POSITIONS. 



6. Port Eoyal. — Telegraphic determination from Havana, by United States Officers, 

 in 1875, placed the flagsbaff at Port Eoyal in long. 76" 50' 38" W. The northern coast, it 

 appears, was placed too far North from 1 to 2 miles. 



7. Portland Eock. — Portland Eock is a single kay, 14 to 20 feet above the sea, and 

 covered with small bushes. It has been variously represented in from lat. 17° 7^' to 

 17° 13', and from long. 76° 32' to 77° 31'. In Mr. De Mayne's Chart it appears in 

 17° li' N., and 77° 29' W. The position given in our Table cannot, we think, be far 

 from the truth. The Officers of H.M.S. Winchester, iu 1834, by numerous altitudes, &c., 

 gained the latitude of the rock as 17° 7' 25", long. 77° 27' 4". 



8. Grand Cayman. — The latitude of the S.W. kay of the Grand Cayman, as observed 

 by Captain Livingstone, August 5th, 1817, appeared to be 19° 14', not 19° 11', the parallel 

 formerly assigned ; the longitude was communicated to us by the late Captain Hurd, as 

 a determination to be relied on, and it appears to have been confirmed by Captain 

 J. W. Monteith. x. 



Don J. M. Herrera, of the Spanish Navy, 1863, placed the East extreme of the Eastern 

 Little Cayman (Cayman Brae) in lat. 19° 45' 15" N., long. 79° 46' 24" E. The S.E. 

 point, according to Mr. Dunsterville, lies in lat. 19° 16' N., long. 81° 6' 40" W. 



The Variation of the Compass is decreasing aroimd the Coasts of Cuba, Jamaica, &c., 

 at the rate of 2|' to 2' per annum.
