From this table it appears, that under the Line and near the tropics,
the water is cooler at a great depth than at its surface. In high
latitudes, the air is cooler sometimes, sometimes very near upon a
par, and sometimes warmer than the sea-water at the depth of about 100
fathoms, according as the preceding changes of the temperature of the
air, or the direction and violence of the wind happen to fall out. For
it is to be observed, that these experiments were always made when we
had a calm, or at least very little wind; because in a gale of wind,
we could not have been able to make them in a boat. Another probable
cause of the difference in the temperature of the sea-water in the
same high latitude, undoubtedly must be sought in the ice; in a sea
covered with high and extensive ice islands, the water should be
colder than in a sea which is at a great distance from any ice." - F.
This table is evidently too confined, and made up of too few elements,
to justify almost any general inferences.
