and fifty years ago. There i cumins, then, to be 

 made a complete survey of all these islands. As 

 to the islands near them, seen by Maurell, it is 

 wit likely that they are the same, as home ha\ e 

 supposed. This is another reason why they should 

 be all explored with the greatest precision. 



IX. Admiralty island t. — It is much to he wished 

 that the islamls seen by Maurell, to the eastward 

 of the Great Admiralty Island, should be explored, 

 since we know that Maun; IPs account of his dis- 

 coveries does not satisfy the hydrographer. 



X. i\VtP Brita in.— Admiral PVEntreeasteaux has 

 seen and determined, with his usual exactness, the 

 islands situated along the north coast of Now 

 Britain ; but he has not been able to lay down the 

 roast it*dfy which he has seen only at a distance, 

 and ROOM parts not all. 



XI. # Low Islamist. — Captain llsvgemuster, of the 

 Russian navy, discovered, in the year NUtO, mi 

 ifdiind to the westward of King George's Island*. 

 This island cannot be any oilier than Schouteti's 

 Waterlamll. Captain Wilson sailed between two 

 islands, which he took to be King George's Is- 

 lands. Must navigators have been of the same 

 opinion; although there is a difference of longi- 

 tude of more than a degree between tlie islands 

 seen by Wdsou and King George's Islands. Cap- I 

 tain Duperrey (an excellent authority, as every 

 hydrographer will reailily admit,) is i>f a different 

 opinion ; he maintains that the two islands be- 

 tween which Wilson sailed arc not King George's 

 Ishnds, but arc situated to the westward of them. 

 He thinks that the island seen by Captain llnge- 

 muster, which I take to be Watorlandt, is one of the 

 two islands ; and that Captain Hagemuster has not 

 seen the other. In order to refute Captain Du- 

 perrey's hypothesis, the second island, which, ac- 

 cording to hi in, Captain Ilagemustcr might not 

 have perceived, ought to be searched for, to 

 the westward of Captain llagemustcr's island ; 

 if it really does exist, it cannot be at a greater 

 distance than about fifteen or twenty miles. 



XII. * Commodore Byron's flftl of IHtOfSfohtt 

 matt have not been visited since their first discovery 

 in 1765. I have endeavoured to settle their longi- 

 tude at 140 J 42' W. (pitge h'7 of my supplement); 

 but this heing only an approximation, they ought 

 to ho surveyed— at least visited anew. 



XIII". By my memoirs, page 2^1, and supple- 

 ment, page <J0, you will perceive that there is u 

 difference of 27' between Captain Bellinghausen's 

 and Captain Kotze hue's longitude of the west point 

 of Prin&s of IFti/raV Island * and the island 

 situated to the westward of it \. What may be 

 the cause of this difference t fcince the two navi- 

 gators do not differ, either before or after, more 

 than three minutes. Either the length of Vlighen 

 Island has been overrated by Captain Kotzebue, 

 or some other error has crept into the longitude of 

 either the one or the other. As both are excellent 

 observers, it would be very desirable tu settle this 

 point, by examining and surveying carefully aJl 

 the islands lying to the westward and eastward of 

 Vlighen Island, and determine with the greatest 

 precision the width of the channels separating the 

 different islands, as well as the exact length of

 buc, Kruscustern Island. 



Vlighen or Prince of Wales's Island: the error 

 will, most likely, be detected in the length of that 

 tele. 



XIV. * There is a difference of 17' in the longi- 

 tude nf the isle Clermont d< T**nnerr« between 

 Captain Duperrey and Captain Ueeehey. .At 

 Serle Island, close to it, there is hardly any dif- 

 ference at all. The same difference of 17' exists 

 in the longitude of Prince William Henry, which 

 Captain Ueeehey has proved to be the same with 

 Captain Duperrey's isle Lortingo ; whereas at 

 MvMn I&faml, both Captains Ueeehey and Du- 

 perrey agree perfectly well. It would bo worth 

 while to search for the cause of such anomalies. 



XV. # Captain Beechey is of opinion that Cap- 

 tain Duperrey's isle CUrnwnl «/e Totintrrc is one 

 and the same wilh the island of Minerva. Cap- 

 tain Duperrey, on the contrary, maintains that the 

 island Minerva is the same as Serle Island. 1 am 

 of this latter opinion; although the solution of this 

 problem will much depend upon the distance of 

 the id.uid Clernii.nl ile Touuerre from Serle 

 Island, which is much less on DupernVs chart 

 than on Captain Ueeehey "s. 



XV* J." There has been lately discovered on 

 island of considerable extent, of the name of 

 Haraka. It would be well to examine it, since 

 the account given of it is not quite satisfactory. It 

 is stated to be situated in Hi, JV S., and 145° W. 



X V H .• 1 have placed on my chart of the Low 

 Islands, several Wands, the position of which is 

 rather doubtful ; for instance, the Hunyrr's (Iruu/i 

 of Tumbull, the island of iSritvmirt, the islands 

 discovered by Quires, aud several others. In 

 order to have any certainty about their existence 

 and precise position, it is necessary to search for 

 and make a survey of them. 



XVI II." The Inlands uf San Bernardo and the 

 Itlamls of iMmjer, — Mtttdaue discovered a group 

 of islands, named by him San Bernardo. These 

 islands have been seen by Captains Freyeinel and 

 Bellioghaiisen. Not far from them Byron dis- 

 covered a small group, which he named Islands of 

 Danger. Notwithstanding a difference of latitude 

 of lialf a degree, the two groups have been con- 

 sidered as one and the .same. It has not heeu 

 thought impossible that in Byron's latitudes there 

 might have been a typographical error: besides, 

 none, of all the navigators who have passed here, 

 have ever found a second group, which they 

 could nut have missed if it really existed. Cap- 

 tain Duperrey, however, who is, as I have said 

 above, a high authority in whatever relates to the 

 hydrography of the South Seas, is of a different 

 opinion ; he maintains that Byron's islands of 

 Danger do exist. In order to settle that question, 

 it t» necessary to search under the meridian nt ihe 

 ishuxls San Bernardo, as determined by Captain 

 Boll inghau sen, for these Islands uf Danger in the 

 latitude assigned to them by Byron, as well as for 

 the chain of rocks of which he speaks, and which 

 are situated, according to him, to the eastward. 

 This has not been done yet, and it would be very 

 desirable if it was done, in order not to leave the 

 least doubt on the Biibiect. 



xix.* Mariemm f demit? On Captain Frey- 



cinet's chart there is to ho seen, to the south-west 

 of the Island of Assumption, rocks, by the name 

 of Mary's. Rocks of the same name have been 

 seen by La Perouse, to tlto northward uf Assuiup-
