Fig. 8 & 9. wave of Febr. 7 1909 is placed above the wave of 29 Jan. 1910. In the second diagram we see this wave placed above that of 19 Jan. 1911. Arranged in this manner the analogy is quite obvious. The difference in the dates at first puzzled me till I found the simple solution. The lunar year is 10 days shorter than the solar. It comprises 12 synodic lunar revolutions, each of 29,531 days, and 13 tropic periods of declination of 27,399 days each. Thus the same lunar phase will recur after nearly 355 days and the moon will attain almost the same declination north or south. 12 x29,531 (synodic revolutions) = 354,57 days 13 x27,399 (periods of declination) = 355,18 days. This means: 1) That the phase and declination of the moon influences the movements in the oceanic border-layer. 2) That if the moon's synodic period of revolution and period of declination at a certain season unite in raising a submarine wave somewhere in the sea, it is not to be expected that new waves will appear regularly every 14th (or 7th) day except for ajimited space of time on either side of the epoch.
