This swell, which was not high, produced an obvious | |effect on the dip angle, as observed, the two horizons alternately | |separating and overlapping; this change was however so slight that I have | |not been able to measure it. | 96|All other circumstances as in Nov. 95. Parts of the horizon observed NE | |and SW. |
