Excerpt: ... tions were made in the summer months. Dryness, in the morning before sunrise, is ordinarily from 6 to 7 degrees, the utmost 12 degrees, the least 3 degrees; which for a mean temperature of 77 degrees, answer to about 17 to 20 centesimal?, 30 and 39 respectively. The atmospheric dryness usually augments as the day advances; for, while the temperature rises towards noon, the point at which the hygrometric thermometer becomes stationary remains more nearly uniform; mean dryness in the morning 7. at noon 14. These observations were made at inland situations, and the minimum of humidity actually noticed has probably not amounted to a fourth of the atmosphere's real capacity for moisture. During the warm season, although the S.E. monsoon predominates, westerly winds are not unfrequent; they are always moist. When south-easterly winds blow, they bring from the shallow sea, over Lagullas bank, humidity, which is condensed upon the summits of the mountains. It is seen rolling down the western cliffs in volumes of thick vapour; and the elevation at which this is dissipated, as it descends, answers precisely to the hygrometric state of the air. Were marks noted upon the precipitous sides of Table Mountain, at intervals of 60 yards in perpendicular height from the base, the number of such divisions below the cloud, familiarly termed the Table Cloth, would correspond with the degrees of dryness exhibited by the hygrometer; for temperature decreases with ascents of heights, about one degree of Fahren heit's scale for every 90 yards of elevation. This will be made plain by citing an instance. Thus, on the 11th of Jan., at Cape Town, temperature, 71. hyg. therm. 58.; a cloud hanging over Table Mountain, not touching it, but just elevated above the summit: the height of T...
