The Hygrometer and Other Meteorological Instruments

Abstract. As was noted in Chapter I, the ancient Greeks had a fairly accurate grasp of the hydrological cycle—the ascent of water from the lakes, rivers, and oceans into the atmosphere, and its return again to the earth as precipitation. One problem with this cyclic concept was that at some stage in the process the water became invisible.
