in the British Museum; and I have since seen single shells more than four times the weight of the above shells and fish taken together.

There were various small channels amongst the reefs, some of which led to the outer breakers, and through these the tide was rushing in when we returned to the ship; but I could not any where see an opening sufficiently wide for the vessels. Low water took place at a quarter past three, which corresponded with the time of high water observed at the preceding anchorage.

It was too late in the day to begin following the line of the high breakers to the north-westward; but we lifted the anchor to remove further from the eastern reef, which was dry within a mile of the ship. The wind was light at south-east; and in steering westward, with a boat sounding a-head, we got into one of the narrow streams of tide which carried us rapidly to the south-west; nor could the boat assist us across, so much was it twisted about by the whirlpools. At six o'clock, being well clear of the stream, an anchor was dropped upon coral sand, in 30 fathoms; at ten, when the ship swung to the ebb, the depth was 33 fathoms, and 28 at low water; as, however, we had two-thirds of a cable out, some of the difference probably arose from the irregularity of the bottom.

Sunday 10.At daylight we steered N.N.W.; but reefs were presently seen all round in that direction, and the course was altered for the small passage through which we had come on the 8th. Such, however, was the change in the appearance of the reefs, that no passage could then be discovered; and fearing to be mistaken, I dared not venture through, but took a more southern channel, where before no passage had appeared to exist. At nine o'clock, having sandy ground in 32 fathoms, and it being very difficult to distinguish the shoals at high water, the anchor was dropped in latitude 20° 56½′ south and longitude 150° 54½′ east. Between one and two in the afternoon, we steered W.N.W. and N.W.; and meeting with a small dry reef at four, hauled up northward, following the line of the great northern reefs upon which the high breakers had been seen. At half
