The curvesof July and September for Stat. 29 (Fig. 18Iexhibit no similar irregularities, and they follow eachother very closely; evidently because the temperaturesare correct in their upper as well as their lower is also noteworthy that the density curves for Stat. 30(Fig. 19) and for Stat. 31 (Fig. 20) show no great differ-ence in density between July (22nd and 23rd! and Sept-ember 6th, 1910. As heavier water-strata cannot as a rule rest uponlighter water-strata, it is fairly easy to see how much. 800
