Cook, New London whalers and others. The material for this zone does not belong exclusively either to the one that precedes or to the one that follows, the limit between the two being the parallel of latitude 55°. It is thought best, therefore, to arrange it in a zone by itself. (Nos. 1 to 16.) Off Cape Horn, longitude 55° to 89° west.
