XX. Caroline Islands. — These islands have been so well surveyed 
by Captain Duperrey and Captain Liitke, that there is very little now 
left to be done concerning them. I shall, however, point out here 
some islands that require to be determined with great precision : 1 . 
The island named by Captain Morell, Fasolis, is most likely the same 
with Captain Liitke's, Farroilep ; but a difference of 21' in latitude, 
makes this doubtful. 2. Island Lydia, on Captain Duperrey's chart. 
We do not know by whom it has been discovered, nor who has 
determined its situation. 3. I have endeavoured to prove, in my 
Supplementary Memoir of the Caroline Islands, that the islands Bor- 
delaire, Fame, Campbell, and the island St. Augustine, are one and 
the same. This hypothesis requires to be verified. 4. The Monte- 
verde Islands ought to be surveyed ; what Captains Monteverde and 
Morell, the only navigators who have seen them, have said of them, 
is not sufficiently satisfactory. 5. We see on Captain Duperrey's 
chart of the Caroline Islands, several islands, of which we know 
nothing more than the name, viz. : Bumkay's, Quekin's, &c, and 
their existence and position remain to be ascertained. 6. The island 
of Arrecifos has, so far as my knowledge extends, been seen only by 
the ship Providence, in the year 1811. Not knowing much respect- 
ing it, it is to be wished that it should be surveyed. 
XXI. The Island of Gilbot. — At the end of my supplementary 
volume, I have pointed out what remains to be done in order to have 
a perfect knowledge of all the islands belonging to this archipelago. 
Remark. — Independent of the American Exploratory Expedition, 
there are to be at the same time three others in the South Seas : two 
English and one French expedition. Many of the islands will of 
course be visited by all the expeditions ; and it is to be apprehended 
that their longitudes, determined by the different astronomers of the 
expeditions, will, perhaps, not agree so well as might be wished. 
This difficulty will of course be obviated, by referring their astrono- 
mical observations to the longitudes of such places as are determined 
by absolute astronomical observations with the greatest precision, 
and those most likely to be visited by the ships of the expeditions. 
The positions we have in the South Seas, are Point Venus, in lon- 
gitude 149° 29' 17" W., determined by the passage of Venus over 
the disk of the sun ; Port Honolulu, in the island of Oaho, by 
occultation of several stars, in 202° 10' E.; and Port lackson, Sydney 
Cove, in 151° 17' E., by an eclipse of the sun. In the northern part 
of the Pacific, East Cape, 190° 16' 10" E., may be adopted as a well-
