Before the ship’s head stretched the dangerous shores of the coral sea, on the north-east coast of Australia. Our boat lay along some miles from the redoubtable bank on which Cook’s vessel was lost, 10th June, 1770. The boat in which Cook was struck on a rock, and, if it did not sink, it was owing to a piece of coral that was broken by the shock, and fixed itself in the broken keel. I had wished to visit the reef, 360 leagues long, against which the sea, always rough, broke with great violence, with a noise like thunder. But just then the inclined planes drew the Nautilus down to a great depth, and I could see nothing of the high coral walls. I had to content myself with the different specimens of fish brought up by the nets. I remarked, among others, some germons, a species of mackerel as large as a tunny, with bluish sides, and striped with transverse bands, that disappear with the animal’s life. These fish followed us in shoals, and furnished us with very delicate food. We took also a large number of gilt-heads, about one and a half inches long, tasting like dorys; and flying pyrapeds like submarine swallows, which, in dark nights, light alternately the air and water with their phosphorescent light. Among the molluscs and zoophytes, I found in the meshes of the net several species of alcyonarians, echini, hammers, spurs, dials, cerites, and hyalleae.
