" This is a low rounded granite rock in False Bay, about eight 

 miles from Simon's Bay, Cape of Good Hope, A perpetual surf 

 washing on the island renders landing difficult. It is inhabited 

 by sea-birds, especially Spheniscus demersus (Jackass Penguin), 

 and Phalacrocorax capensis (Cape Cormorant)."
