[_And in still showers._ l. 260. The allegorical interpretation of the very antient mythology which supposes Jupiter to represent the superior part of the atmosphere or ether, and Juno the inferior air, and that the conjunction of these two produces vernal showers, as alluded to in Virgil's Georgics, is so analogous to the present important discovery of the production of water from pure air, or oxygene, and inflammable air, or hydrogene, (which from its greater levity probably resides over the former,) that one should be tempted to believe that the very antient chemists of Egypt had discovered the composition of water, and thus represented it in their hieroglyphic figures before the invention of letters. In the passage of Virgil Jupiter is called ether, and descends in prolific showers on the bosom of Juno, whence the spring succeeds and all nature rejoices. Tum pater omnipotens foecundis imbribus Aether Conjugis in gremium laetae descendit, et omnes Magnus alit, magno commixtus corpore, faetus. Virg. Georg. Lib. II. l. 325.] VII. "NYMPHS OF AQUATIC TASTE! whose placid smile Breathes sweet enchantment o'er BRITANNIA'S isle; Whose sportive touch in showers resplendent flings Her lucid cataracts, and her bubbling springs; 265 Through peopled vales the liquid silver guides, And swells in bright expanse her freighted tides. YOU with nice ear, in tiptoe trains, pervade Dim walks of morn or evening's silent shade; Join the lone Nightingale, her woods among, 270 And roll your rills symphonious to her song; Through fount-full dells, and wave-worn valleys move, And tune their echoing waterfalls to love; Or catch, attentive to the distant roar, The pausing murmurs of the dashing shore; 275 Or, as aloud she pours her liquid strain, Pursue the NEREID on the twilight main. --Her playful Sea-horse woos her soft commands, Turns his quick ears, his webbed claws expands, His watery way with waving volutes wins, 280 Or listening librates on unmoving fins. The Nymph emerging mounts her scaly seat, Hangs o'er his glossy sides her silver feet, With snow-white hands her arching veil detains, Gives to his slimy lips the slacken'd reins, 285 Lifts to the star of Eve her eye serene, And chaunts the birth of Beauty's radiant Queen.-- O'er her fair brow her pearly comb unfurls Her beryl locks, and parts the waving curls, Each tangled braid with glistening teeth unbinds 290 And with the floating treasure musks the winds.-- Thrill'd by the dulcet accents, as she sings, The rippling wave in widening circles rings; Night's shadowy forms along the margin gleam With pointed ears, or dance upon the stream; 295 The Moon transported stays her bright career, And maddening Stars shoot headlong from the sphere. [_Her playful seahorse._ l. 277. Described form an antique gem.]
