       (a) A division of the log line, serving to measure the
           rate of the vessel's motion. Each knot on the line
           bears the same proportion to a mile that thirty
           seconds do to an hour. The number of knots which run
           off from the reel in half a minute, therefore, shows
           the number of miles the vessel sails in an hour.
           Hence:
       (b) A nautical mile, or 6080.27 feet; as, when a ship

       coverts white, barred with dusky. The lower parts are
       pale brown, with the flanks and under tail coverts white.
       When fat it is prized by epicures. Called also {dunne}.
   Note: The name is said to be derived from King Canute, this
         bird being a favorite article of food with him.
               The knot that called was Canutus' bird of old, Of
               that great king of Danes his name that still doth
               hold, His appetite to please that far and near
               was sought.                        --Drayton.
