Joseph Banks Journal

This morn calm again: went out shooting, killd another new procellaria, aequorea, and many of the sorts we had seen yesterday; caught Holothuria angustata, a species of floating helix much smaller than those under the line, Phyllodoce velella very small, sometimes not so large as a silver penny yet I beleive the common species; in the evening went out again, killd an albatross Diomedaea exulans, who measurd 9 ft 1 inch between the tipps of his wings, and struck one turtle testudo caretta.

Sydney Parkinson’s Journal

We observed an eclipse of the moon; and about seven in the morning a bright cloud in the west, from which a stream of fire proceeded: it bore away to the westward, and about two minutes after we heard two loud explosions like that of a cannon; and then the cloud soon disappeared.
