AIR.

As we have passed through the water, let us now investigate her sister fluid, the air. They are both necessary to life, and the purity of both to the prolongation of it; this small difference lies between them, a man may live a day without water, but not an hour without air: If a man wants better water, it may be removed from a distant place for his benefit; but if he wants air, he must remove himself.--The natural air of Birmingham, perhaps, cannot be excelled in this climate, the moderate elevation and dry soil evinces this truth; but it receives an alloy from the congregated body of fifty thousand people; also from the smoke of an extraordinary number of fires used in business; and perhaps, more from the various effluvia arising from particular trades. It is not uncommon to see a man with green hair or a yellow wig, from his constant employment in brass; if he reads, the green vestiges of his occupation remain on every leaf, never to be expunged. The inside of his body, no doubt, receives the same tincture, but is kept clean by being often washed with ale. Some of the fair sex, likewise are subject to the same inconvenience, but find relief in the same remedy.
