PICTURE OF CONSTANTINOPLE.

[From the French of Lebrun.)
Queen of the Morn! Sultana of the East!
City of wonders, on whose sparkling breast,
Fair, slight, and tall, a thousand palaces
Fling their gay shadows over golden seas !
Where towers and domes bestud the

gorgeous land,
And countless masts, a mimic forest, stand;
Where cypress shades the minaret's snowy bue,
And gleams of gold dissolve in skies of blue.
Daughter of Eastern art, the most divine-
Lovely yet faithless bride of Constantine-
Fair Istamboul, whose tranquil mirror flings
Back with delight thy thousand colourings,
And who no equal in the world dost know,
Save thy own image pictured thus below!

Dazzled, amazed, our eyes balf-blinded, fail,
While sweeps the phantasm past our gliding sail —
Like as in festive scene some sudden light
Rises in clouds of stars upon the night.
Struck by a splendour never seen before,
Drunk with the perfumes wafted from the shore,
Approaching near these peopled groves, we deem
That from enchantment rose the gorgeous dream;
Day without voice, and motion without sound,
Silently beautiful! The haunted ground
Is paved with roofs beyond the bounds of sight,
Countless, and coloured, wrapped in golden light.
'Mid groves of cypress, measureless and vast,
In thousand forms of circles-crescents-cast,
Gold glitters, spangling all the wide extent,
And flashes back to heaven the rays it sent.
Gardens and domes, bazaars begem the woods;
Seraglios, barems-peopled solitudes,
Where the veiled idol kneels; and vistas, through
Barred lattices, that give the enamoured view,
Flowers, orange-trees, and waters sparkling near,
And black and lovely eyes.-Alas, that Fear,
At those heaven-gates, dark sentinel should stand,
To scare even Fancy from her promised land !

METEORIC APPEARANCES. Alloa, Monday evening, half past 8 o'clock, 15th Sept, 1828. Meteor.-A splendid luminous arch appeared in the heavens, embracing the whole horizon, from south-west to north-east, while its breadth seemed to be little more than that of a rainbow. The night was calm and clear, and before the arch appeared several columns of the aurora borealis were seen in the north, which continued luminous a considerable time. The light of the meteor was very much the same as that of the aurora borealis only that it was stationary. It retained its brilliancy and beauty for about an hour, when it gradually melted away. This interesting object was also seen in Edinburgh and Glasgow. This phenomenon, interesting from the rarity of its occurrence, was, in the present instance, rendered still more so from being in opposition to the received notions of the causes which are believed to produce it, and the season of its appearance. It has been supposed, that they appear only at the full of the Moon; now, the bow in question appeared just at the time the Moon set, and which, instead of being at its full, was only nine days old, and there was no rain at the time, the evening being uncommonly serene, the sky almost unclouded, and the air rather dry and frosty than humid; the thermometer at the time stand, ing at 50, and the barometer rather above 30.--Com. municated by William Brodie, Esq.

At ten minutes past six o'clock one evening lately (January 1828), a luminous arch appeared across the heavens, stretching directly from the magnetic east and west through the zenith-the east extremity being by far the most intense in light, and narrower than the west one. The east end appeared much more compact than the west; the latter having the appearance of streaks of light. The centre, which passed directly through Cassiopeia, had the appearance of flocci, and at least three times the breadth of the west end, and four times that of the east. About 20° far. ther north another arch of light appeared, quite distinct from the former, but much thinner; its ends terminated in the extremities of the larger bow. The north horizon exhibited the aurora by appearing like the sky when illuminated by the rising Sun. Round the Moon was a very distinct balo, and she had attained the altitude of about 50°. In the south were thick white clouds, which concealed the south horizon. After the appearance had continued about ten minutes, the larger bow began to move at the centre towards the south, and to increase in breadth, the extremities remaining stationary; and this continued till the part of the bow that had been in the zenith united with the clouds, the smaller bow advancing in the same degree. When the centre of the bow bad moved about 20° toward the south, the balo entirely disappeared. The bow, during the whole time, seemed to have motion from one extremity to the other, as though impelled by wind from the west to the east.

The wind at the surface of the earth was at the same same time north-west by north. The thermometer was 40°, the barometer 30:30, and had risen during the day from 30-07. The whole appearance lasted about half an hour, after which the whole sky was clear, except in the south. No streamers were visible, except from the east end, whence a few large ones moved towards the magnetic north, but rather sloggishly. The weather changed during the night, by
