Sunset in these regions is a magnificent spectacle. The play of colours in the heavens is quite indescribable. When the moon rises, the same thing occurs. Opposite the orb, a huge pile of vapour rises in shadowy forms, on which the light is thrown, producing the most wonderful effects. In these chromatic displays, red is the colour that predominates. Towards midnight, the wind begins to blow from the east, at first gently, but icy cold, for it comes from the regions of perpetual frost and snow. The radiation of heat from such an extensive and almost glowing surface is naturally very great and rapid, and after midnight it begins to freeze. An hour before sunrise, all stagnant water is frozen over; and the thermometer falls sometimes to 28 degrees Fahrenheit--on an average it is at 32 degrees--to rise again at noon to 90 degrees. THINGS TALKED OF IN LONDON. _October_ 1852. The death of the great Duke has for a time kept other subjects of conversation in abeyance; but by slow degrees the old hero slides into the past, and the tongues and pens of thousands are busily recalling the words, works, and exploits by which he won for himself 'imperishable renown.' His life presents itself to us in different aspects, wherein the lowliest as well as the loftiest may find something exemplary; and all may learn a lesson in that virtue of virtues--persevering straightforwardness. By and by, we shall have a magnificent funeral; and then, as new events follow, we shall find whether new men are to come capable of meeting them; whether there are to be heroes after Agamemnon as well as before. The remains of the Great Exhibition building are fast disappearing from Hyde Park, under the busy hands of the troops of workmen engaged in the business of taking down and removal. Heavily-laden wagons are continually departing from each entrance, and every hour the prodigious mass of materials is diminished. The spectacle is a striking one in many respects, and would be a melancholy one were it not for the certainty of restoration. Already the grass is beginning to grow on the ground, worn bare by millions of feet; and before many months are over, the greensward will again cover the site of the world's Temple of Industry. Among the objects of most interest to be comprised in the new Palace, are galleries of Classic and Mediaeval Art, a Nineveh and Egyptian Court, Etruscan Restorations, Hall of the Alhambra, Court of Inventions, besides complete illustrations of the races of Man, to be arranged by Dr Latham, which will afford valuable aid to the student of ethnology; and of natural history and geology, all to be superintended by able professors. Seeing that there is talk of enlarging the British Museum, which is not half large enough for its purpose, might not some of its long-hidden contents be transferred, under proper regulations, to the Palace at Sydenham?
