the fea, which was quite calm (it being a fine day, 
and no wind ftirring) was obferved to retire fud-

five times between high water and low water mark, 
the undulations continually decreafing (not unlike 
the vibrations of a pendulum) it fubfided, and the

The feafon of the year has been more than ordi-
