in sea affairs, a ship employed in the coal trade, formed from the Norwegian model. It is distinguished by a narrow stern, projecting quarters, a deep wale, and by having ornamental figures on the prow. These vessels are generally built remarkably strong, and carry from four to six hundred tons, or, in the language of their own mariners, from 20 to 30 keels of coals.

is also a sort of strong tackle, or combination of pulleys, to hook and draw the anchor perpendicularly up to the cat-head. See CAT-HEADS.

CAT'S-EYE, or Sun-stone of the Turks, a kind of gem found chiefly in Siberia. Cat's-eye is by the Latins called oculus cati, and sometimes onycoporus, as having white zones or rings like the onyx, and its colours variable like opal, from which last it differs chiefly by its superior hardness. It is very hard, and semitransparent, and has different points, from whence the light is reflected with a kind of yellowish radiation somewhat similar to the eyes of cats, from whence it had its name. The best of them are very scarce, and jewellers cut them round to the greatest advantage. One of these stones, an inch in diameter, was in the possession of the duke of Tuscany.
