{159} The Calenture.—[From the Spanish Calentura, a fever peculiar to sailors within the tropics—
"So, by a calenture misled, The mariner with rapture sees, On the smooth ocean's azure bed, Enamelled fields and verdant trees: With eager haste he longs to rove In that fantastic scene, and thinks It must be some enchanted grove; And in he leaps, and down he sinks."
Swift, The South-Sea Project, 1721, ed. 1824, xiv. 147.]
