The above-mentioned two small islands on the reef lay directly North, and the southern part of the first cluster of Pallisers was no longer visible. Viewed from this spot, the smaller ones might have been mistaken by us also for part of another group, if we had not previously ascertained that they were connected with the first by means of the reef. The second and third group could also be seen from this point; the former to the S.E. the latter S.W. At six o'clock in the evening, we found ourselves near the eastern point of the third group, and saw from the mast-head the Greigh Islands, discovered by Captain Bellingshausen. We now steered between these two groups, in order to free ourselves from the Archipelago, and regain the open sea. Again the night was tempestuous; but a calm occurred in the course of it, which, had it lasted longer, would have been dangerous, as a strong current was carrying us towards the shore. The morning sun, as usual in the Torrid Zone, dispersed the clouds and restored the beautiful blue of the tropical sky. We soon lost sight of land, but a black cloud still lowered in that part of the horizon where it had disappeared; a proof how powerfully these masses of coral attract thunder clouds. We now recovered the south-east wind, and favoured by it, took the shortest way to O Tahaiti. All the longitudes in the dangerous Archipelago which I have given, (without entering into the manner in which they were calculated,) are made out by means of the chronometer. This, on arriving at O Tahaiti, was found six minutes fifty seconds wrong; and the longitudes here given have been rectified accordingly. The following is from our observations the situation of the Palliser Islands:-- South point of the first group. Lat. 15° 34' 25" Long. 146° 6' 49" The two small islands to the West of the first group Lat. 15° 30' 15" Long. 146° 20' 50" The Eastern point of the third group Lat. 15° 44' 52" Long. 146° 28' 2".
