CROZET ISLANDS, an uninhabited group in the Indian ocean, in 46°-47° S. and 51° E., belonging to Britain. They are mountainous, with summits from 4,000-5,000f t. high and include two groups—Penguin or Inaccessible, Hog, Possession and East islands; and the Twelve Apostles. Like other islands in these waters, they appear to be of igneous formation; but owing to the bleak climate and their inaccessible character they are seldom vis ited. They were discovered in 1772 by Marion-Dufresne, after one of whose officers they are named. Possession, the loftiest, has a snow-clad peak said to exceed S,000f t. The hogs let loose by an English captain on Hog island have disappeared, the rabbits survive.
