Note 42 — Chapter II · PENDULUM ISLAND. STATE OF THE ICE NORTHWARDS. LANDING ON SHANNON ISLAND.
Lewis Page Mercier translation
According to our later observations the harbour time on this spot was 12h. 0m., consequently high water on this day was at 6h. 41m.; the current noticed must therefore be ascribed to some local influence, especially as the tidal wave ran to the north.—Koldewey.
