ABSTRACT
IN CONTRAST with the decline of interest in other branches of marine science, tidal studies remained active during the early eighteenth century but, after Halley's voyage, the initiative passed to the other side of the Channel, particularly to France. The Academic Royale des Sciences had observations made at Dunkirk in 1701-1702 and at Brest in 1714-1716 and the results were published by Jacques Cassini (1677-1756). Observations continued to be made at intervals throughout the century in different places.1
