They are fixed into the windows so that the passengers may turn them round from time to time to raise the water from the lower half to the top, whence it trickles back again and cools the heated air that percolates through.
The conclusion is evident: the Epeira's glue is a substance that absorbs moisture freely. In an atmosphere with a high degree of humidity, it becomes saturated and percolates by sweating through the side of the tubular threads. These data explain certain facts relating to the work of the net. The full-grown Banded and Silky Epeirae weave at very early hours, long before dawn.
During the wet season water percolates freely from the surface down through the lodes, and the gold set free by the decomposition of the ore at the surface must be carried down into it, so that in the course of ages, during the gradual degradation and wearing away of the surface, there has, I believe, been an accumulation of the loose gold in the upper parts of the lodes from parts that originally stood much higher, and have now been worn away by the action of the elements.
They cannot say that it is in the earth above the level of the sea: for, the same appearances are found as deep as we can examine below that level; besides, we see that water has the opposite effect upon the surface of the earth, through which it percolates dissolving soluble substances, and thus resolving solid bodies in preparing soil for plants.
Then it is ground, and placed in a coffee-pot with a filter through which, when it has yielded up its life to the boiling water poured upon it, the delicious extract percolates in clear drops, the coffee-pot standing on a heated stove to maintain the temperature. The nose of the coffee-pot is stopped up to prevent the escape of the aroma during this process.
The stalagmites were all a little concave, and the cavities were filled with water. The water percolates through the roof, a drop at a time often the drops several minutes apart and more or less charged with mineral matter. Evaporation goes on slowly, leaving the mineral behind.
The waters from which Bath gets its fame are believed to owe their origin to the surface drainage of the E. Mendips, which percolates through some vertical fissure, perhaps at Downhead, to the heart of the hills, and are conducted by some natural culvert beneath the intervening coal measures, washing out as they go the soluble mineral salts, and whilst still retaining their heat emerge again at the first opportunity at Bath.

In fact, there are vast tracts of land bordering the shore, which lie so low that dikes have to be built to keep out the sea. In these cases, there are lines of windmills, of great size and power, all along the coast, whose vast wings are always slowly revolving, to pump out the water which percolates through the dikes, or which flows from the water-courses after showers of rain.
Of course, all the fluid matter deposited upon the surface that does not exhale in the atmosphere percolates through this loose stratum until it reaches the rock, where it stagnates and corrupts, returning into the air in the form of poisonous gases, instead of undergoing the healthy transformation which is effected in all soils capable of sustaining vegetable life.
