They are harmless & timid creatures & always run from their assail- ant except when wounded, when in that predicament they sometimes turn on their pursuer. We found them to be excellent eating, & much superior to the green turtle. An aquatic species of smaller size and less frequent occurrence was also procured & I succeeded in preserving an example of it. The shore abounded in a large species of Lacerta. It is probably one of the largest species of the genus. Snakes are said to be frequent on these islands, & to be of large size. During the three days we were on the island not a single serpent was seen by any individual of our party.

To one whose knowledge of rocks & of geological phe- nomena had been confined to the primitive & transition districts of Scotland, James Island presents a new series of geological phenomena of the utmost interest to those who cultivate that science. The appearance of the island varies in different places; in some parts the coast rises into perpendicular ragged
