There are no features to this land, no conspicuous, far-famed landmarks for the eye; there is nothing so far down to tell you of the greatest agglomeration of mankind on earth dwelling no more than five and twenty miles away, where the sun sets in a blaze of colour flaming on a gold background, and the dark, low shores trend towards each other.

In reality, it was an infinite agglomeration of coloured infusoria, of veritable globules of jelly, provided with a threadlike tentacle, and of which as many as twenty-five thousand have been counted in less than two cubic half-inches of water.

The ether, my friend, is an agglomeration of imponderable atoms, which, relatively to their dimensions, are as far removed from each other as the celestial bodies are in space.
