an inflated rock on the western coast of Scotland, between the shores of Ayrshire and Cantire. It is two miles in circumference at the base, is accessible only at one place, and rises to a great height in a pyramidal form. A few goats and rabbits pick up a subsistence among the short grass and furze; but the importance importance of the rock confits in the great variety and immense numbers of birds which frequent it, particularly the gannets or folan geese, some of which are taken for the table, and others for the feathers. The rock is rented from the earl of Carlisle at £25 per annum. The depth of water around the base is from 7 to 48 fathoms. It is surrounded with excellent banks, well stocked with cod and other white fish. On one part of the rock are the remains of an old castle, which is said to have been erected by Philip II. of Spain, about the time that the Spanish armada invaded Britain.
