Fair wind and steady tho but little of it.

Sydney Parkinson’s Journal

On the 24th, we caught a logger-head tortoise, which weighed one hundred and fifty pounds; and shot several birds, one of which was an albatros, that measured, from the tip of one wing to the other, nine feet one inch; and from the beak to the tail two feet one inch and a half. Some time after, we met with some birds of the same kind that measured fourteen feet from the tips of the wings.

The thermometer, in the middle of the day, was from 66 to 69; and in the evening 62, when the air was not so dry.
