During a calm, on the morning of the 2d, some parts of the sea seemed covered with a kind of slime, and some small sea-animals were swimming about. The most conspicuous of which were of the gelatinous or _medusa_ kind, almost globular; and another sort smaller, that had a white or shining appearance, and were very numerous. Some of these last were taken up, and put into a glass cup with some salt water, in which they appeared like small scales or bits of silver, when at rest, in a prone situation. When they began to swim about, which they did, with equal ease, upon their backs, sides, or belly, they emitted the brightest colours of the most precious gems, according to their position with respect to the light. Sometimes they appeared quite pellucid, at other times assuming various tints of blue, from a pale sapphirine to a deep violet colour; which were frequently mixed with a ruby or opaline redness; and glowed with a strength sufficient to illuminate the vessel and water. These colours appeared most vivid when the glass was held to a strong light; and mostly vanished on the subsiding of the animals to the bottom, when they had a brownish cast. But, with candle light, the colour was, chiefly, a beautiful pale green, tinged with a burnished gloss; and, in the dark, it had a faint appearance of glowing fire. They proved to be a new species of _oniscus_, and, from their properties, were, by Mr Anderson, (to whom we owe this account of them), called _oniscus fulgens_; being probably an animal which has a share in producing some sorts of that lucid appearance, often observed near ships at sea in the night. On the same day two large birds settled on the water, near the ship. One of these was the _procellaria maxima_ (the _quebrantahuessos_), and the other, which was little more than half the size, seemed to be of the _albatross_ kind. The upper part of the wings, and tip of the tail, were black, with the rest white; the bill yellowish; upon the whole not unlike the sea-gull, though larger.
