But our machines have now been running for 70. or 80. years, and we must expect that, worn as they are, here a pivot, there a wheel, now a pinion, next a spring, will be giving way: and however we may tinker them up for awhile, all will at length surcease motion. Our watches, with works of brass and steel, wear out within that period.
