On the 19_th_ and 20_th_ the mercury in the barometer sunk gradually from 30 to 29-02, and rose again as before on the 21st. It blew hard; the thermometer fell to 58°, in latitude 42° S. There are many albatrosses and stormy petrels about the ship. _22d_.--Latitude 46° 25' S., longitude 52° 40' W. The weather very cold, though the thermometer is at 56°, barometer 29-08; a very heavy swell. Great numbers of the Cape pigeon about the ship. _24th_.--Latitude 50° 30'; thermometer 44° morning and evening, 47° at noon. Seeing two penguins to-day, we supposed some land must be near, but found no bottom with 100 fathoms line. The cold weather seems to have a good effect on our invalids. The barometer fell suddenly, and a strong S.W. wind succeeded, and we were glad to light a fire in the cabin. I am sorry we have passed so far out of sight of the Falkland Islands, Sir John Hawkins’s maiden land. The idea of seeing a town left standing as it was, by all its inhabitants at once, and of the tame animals becoming wild, had something romantic. It seemed like a realisation of the Arabian tale of the half-marble prince, and in real interest comes near the discovery of the lost Greenland settlements. I do not know any thing that gratifies the imagination, more than the situations and incidents that by bringing distant periods of time together, places them, as it were, at once within our own reach. I remember some years ago spending a whole day with no companion but my guide at Pompeii, and becoming so intimate with the ancients, their ways, and manners, that I felt, when I went home to Naples, and its lazaroni, and its English travellers, as I suppose, that one of the seven sleepers to have done, who went to purchase bread with money five centuries old. As to the marble cities of Moorish Africa, when we consider their exposure to the sirocco, and read Dolomieu's Experiments on the Atmosphere, during the prevalence of that wind at Malta, we shall find but too probable a reason for their existence as reported.
