Tables CLVIII to CLXI show the same general behavior of sea water as shown for land water in Tables CLIV to CLVII. The rate of absorption was rapid upon first exposure to the air and diminished with time, until near the point of saturation, when the absorption proceeded very slowly. By a comparison of the results obtained with land water and sea water, it is seen that the latter recovers its oxygen at a slightly more rapid rate than the former. The
