_(For the Mirror.)_
This disease, according to Dr. Darwin, is an unconquerable desire of
returning to one's native country, frequent in long voyages, in which
the patients become so insane, as to throw themselves into the sea,
mistaking it for green fields or meadows:--
"So, by a _calenture_ misled,
The mariner with rapture sees,
On the smooth ocean's azure bed,
Enamell'd fields and verdant trees.
With eager haste he longs to rove
In that fantastic scene, and thinks
It must be some enchanting grove,
And in he leaps, and down he sinks."
