NEW ORKNEY, a group of islands in the South Atlantic Ocean, lying between 60. and 61. S. Lat., about 675 miles S.E. of Cape Horn. The principal island is called Mainland or Pomona, and another, called Saddle Island, has a lofty mountain, known by the name of Noble's Peak, which is visible from a distance of nearly 70 miles. The islands are all covered with high and rugged hills; and there are found here large numbers of seals, and immense flocks of sea-fowl. This group forms a part of New South Shetland.
