Now, for the first time, I saw what is called the zodiacal light. It commenced below the horizon with a considerable breadth, and as luminous as a moderate aurora, and extended upward in the direction of the star Aldebaran, thus forming a triangle. Mr Vernon explained to me the supposed cause of this phenomena. It is that the sun is surrounded by a mass of nebulous matter, of which this light is but a manifestation. Some philosophers have an idea that the matter has solid particles in it, which, when they pass through the earth's atmosphere, produce shooting stars, or are drawn towards it in the shape of meteoric stones. It is seen always, it must be remembered, nearly in the elliptic, or sun's path. Now, too, my eyes gazed for the first time on the magnificent constellation of the Southern Cross, which rose night after night higher in the heavens. Greater, also, grew the heat, till it was impossible to sit, walk, or stand--indeed, to exist--without being in rather an uncomfortable state of moisture. I had expected to see more living beings--birds and fish--than we had hitherto met with. When the ocean was rough, only the larger sorts--whales and dolphins, porpoises and sharks--were likely to be distinguishable; and now in the calmer and hotter latitudes the inhabitants of the deep seemed to eschew the surface, and to keep to the cooler regions below. Now and then, however, as some of the sportsmen on board declared, we flushed a covey of flying-fish, or rather, they rose out of the water to avoid their enemy the bonito. A hundred yards is said to be the utmost extent of their flight; and that is a good flight, considering the weight of their bodies and the size of their gauze-like wings. They can also turn at an angle; but they seldom rise more than a dozen or twenty feet above the surface. They thus frequently fall on the decks of vessels of no great burden. When getting up a bucket of water from alongside, I was often interested in examining the variety of minute creatures which it contained. Among others, I found some beautiful specimens of swimming crabs, with paddles instead of the usual sharp-pointed legs, by which they propel themselves rapidly along.
