The colour of the electric lights has a strange effect in giving a complementary tint to the air in the early evening.--ESSAY ON LONDON.

O, Heavenly colour! London town
Has blurred it from her skies;
And hooded in an earthly brown,
Unheaven'd the city lies.
No longer standard-like this hue
Above the broad road flies;
Nor does the narrow street the blue
Wear, slender pennon-wise.

But when the gold and silver lamps
Colour the London dew,
And, misted by the winter damps,
The shops shine bright anew--
Blue comes to earth, it walks the street,
It dyes the wide air through;
A mimic sky about their feet,
The throng go crowned with blue.
