tering on this curious
and copious theme, I feel anxious to carry our convoy fairly across
the tropical regions; after which an account of the Trades will be
better understood.

I have just mentioned that the changes of temperature, on a voyage to
India, are most remarkable. We set sail, for instance, in the month
of March, when it was bitterly cold in England; then we came off the
coast of Spain, where it was a little more moderate; next to Madeira,
which is always agreeable. Then we passed the Canaries; after which we
sailed over the tropic of Cancer, and got well toasted in the torrid
zone; steered down upon the equinoctial line, passed the tropic of
Capricorn, and again became conscious of the weakened influence of the
sun; till, at length, off the Cape of Good Hope, we were once more
nipped with the cold. Anon, having rounded the south point of Africa,
we put our heads towards the line, and a second time, within a few
weeks, emerged from the depth of winter into the height of summer.

The proximate cause of all these vicissitudes was, of course, our
approach towards and removal from the direct influence of the great
source of light and heat. At one time, the sun, even at noon, was seen
creeping stealthily along, low down in the horizon, at another his
jolly countenance was blazing away right overhead. On the 5th of May,
when our latitude was 17-1/2 deg. N., the sun's declination was 16-1/4 deg.
N., his centre being only one degree from our zenith: shadows we had
none. On that day we saw St. Antonio, the north-westernmost of the
Cape de Verde Islands, the summit of which is about seven thousand
feet above the sea.

On the next day I well remember going on deck with a certain flutter
of spirits, to see, for the first time in my life, the sun to the
northward, and moving through the heavens from right to left, instead
of from left to right. No one doubts that the earth is round; yet
these conspicuous and actual proofs of its rotundity always amuse the
fancy, and frequently interest the judgment, almost as much as if they
were unexpected. The gradual rise, night after night, of new stars and
new constellations, belongs to a still higher order of curiosity; for
it not merely places well-known objects in strange positions, but
brings totally new subjects of contemplation before our eyes, and
leads us to feel, perhaps more strongly than upon any other occasion,
the full gratification which novelty on the grandest scale
