our fiſhermen, was a very fine dorado (coryphæna hyppurus). This was ſufficient to put the whole crew in motion; but the fiſherman had the mortification of finding only a part of its gills upon his hook, as he had drawn the line too haſtily.
Since our departure from Teneriffe the wind had blown pretty ſteadily from the N.E. point.
A ſwallow of the common ſpecies (hirundo ruſtica), undoubtedly lately come from Europe, followed us for ſome time, without lighting upon the veſſel; but ſoon directed its flight right towards the African coaſt, where it was ſure of finding the inſects on which it feeds. We were now about 28° N. lat. 22° 30′ E. long.
As there was very little wind, we obſerved a great number of the meduſa caravela floating upon the ſurface of the water. This plant ſhould not be touched unguardedly, as, like many other kinds of ſea-nettles, it raiſes bliſters upon the hand, that afterwards become very painful.
The ſpecies of remora, known by the name of echineis remora, generally follows the ſhark, as it finds ſufficient nouriſhment in the excrements of that voracious fiſh. It does not, however, attach itſelf ſo excluſively to the ſhark as not to follow other large fiſhes alſo, and even veſſels, to which it fixes itſelf when it is fatigued with ſwimming.
