coruscation.

This extraordinary illumination of the sea is of very unfrequent
occurrence, and rarely happens after long-continued, violent storms.
The captain told me that he had never yet beheld the sea so lighted
up. For my part, I shall never forget the sight.

A second, and hardly less beautiful, spectacle came under our
observation at another time, when, after a storm, the clouds, gilt
by the rays of the sun, were reflected as in a mirror on the bosom
of the sea. They glittered and shone with an intensity of colour
which surpassed even those of the rainbow.

We had full leisure to contemplate Eddystone Lighthouse, which is
the most celebrated building of the kind in Europe, as we were
cruising about for two days in sight of it. Its height, and the
boldness and strength with which it is built, are truly wonderful;
but still more wonderful is its position upon a dangerous reef,
situated ten miles from the coast; at a distance, it seems to be
founded in the sea itself.

We often sailed so near the coast of Cornwall, that not only could
we plainly perceive every village, but even the people in the
streets and in the open country. The land is hilly and luxuriant,
and appears carefully cultivated.

During the whole time of our cruising in the Channel, the
temperature was cold and raw, the thermometer seldom being higher
than 65 to 75 degrees Fah.
