 notwithstanding the stormy weather, some 

 heights of the sun. at the moment when we be- 

 lieved ourselves, though twelve miles distant, in 

 the meridian of the center of the Great Cay- 

 man, which is covered with cocoa-trees. I 

 have discussed in another place % the position 

 of the Great Cayman and the two islands on 

 the east. Those points have long wandered on 

 our hydrographic charts, and I fear that I have 

 not been more fortunate than other observers, 

 who flattered themselves they had made known 

 its real position. The fine maps of the Depo- 

 sito de Madrid, have, at different periods, 

 marked the eastern cape of the Great Cayman, 

 (in 1799-1804), long. 82° 58'; (in 1809), 83° 

 40'; (in 1821), again 82° 59'. The latter posi- 

 tion, indicated on the map of M. Barcaiztegui, 

 is identical with that on which 1 fixed ; but it 

 now appears certain, from the assertion of a 

 very able navigator, Rear-Admiral Roussin, to 

 whom we owe an excellent work on the coast
