Saussure's hygrometer is now warmer than the air in which it is immersed, and in consequence becomes dryer than before, by warming the air which immediately surrounds it, a part of its moisture evaporating along with its heat.] 2. "SYLPHS! your soft voices, whispering from the skies, Bade from low earth the bold MONGULFIER rise; 145 Outstretch'd his buoyant ball with airy spring, And bore the Sage on levity of wing;-- Where were ye, SYLPHS! when on the ethereal main Young ROSIERE launch'd, and call'd your aid in vain? Fair mounts the light balloon, by Zephyr driven, 150 Parts the thin clouds, and sails along the heaven; Higher and yet higher the expanding bubble flies, Lights with quick flash, and bursts amid the skies.-- Headlong He rushes through the affrighted air With limbs distorted, and dishevel'd hair, 155 Whirls round and round, the flying croud alarms, And DEATH receives him in his sable arms!-- So erst with melting wax and loosen'd strings Sunk hapless ICARUS on unfaithful wings; His scatter'd plumage danced upon the wave, 160 And sorrowing Mermaids deck'd his watery grave; O'er his pale corse their pearly sea-flowers shed, And strew'd with crimson moss his marble bed; Struck in their coral towers the pausing bell, And wide in ocean toll'd his echoing knell. [_Young Rosiere launch'd_. l. 148. M. Pilatre du Rosiere with a M. Romain rose in a balloon from Boulogne in June 1785, and after having been about a mile high for about half an hour the balloon took fire, and the two adventurers were dashed to pieces on their fall to the ground. Mr. Rosiere was a philosopher of great talents and activity, joined with such urbanity and elegance of manners, as conciliated the affections of his acquaintance and rendered his misfortune universally lamented.
