CAT-GUT, a denomination given to small strings for saddles, and other instruments, made of the intestines of sheep or lambs, dried and twisted together, either singly, or several together. These are sometimes coloured red, sometimes blue, but are commonly left whitish or brownish, the natural colour of the gut. They.
Cat-harp-ings. They are also used by watch-makers, cutlers, turners, and other artificers. Great quantities are imported into England, and other northern countries, from Lyons and Italy.
Cat-Harpings, a purchase of ropes employed to brace in the shrouds of the lower masts behind their yards, for the double purpose of making the shrouds more tight, and of affording room to draw in the yards more obliquely, to trim the sails for a side-wind, when they are said to be close hauled.
Cat-Heads, two strong short beams of timber, which project almost horizontally over the ship's bows on each side of the bow-sprit; being like two radii which extend from a centre taken in the direction of the bow-sprit. That part of the cat-head which rests upon the forecastle, is securely bolted to the beams: the other part projects like a crane as above described, and carries in its extremity two or three small wheels or sheaves of brass or strong wood, about which a rope called the cat-fall passes, and communicates with the cat-block, which also contains three sheaves. The machine formed by this combination of pulleys is called the Cat, which serves to pull the anchor up to the cat-head, without tearing the ship's sides with its flukes. The cat-head also serves to suspend the anchor clear of the bow, when it is necessary to let it go: it is supported by a sort of knee, which is generally ornamented with sculpture. See Plate CXXVIII.
The cat-block is filled with a large and strong hood, which catches the ring of the anchor when it is to be drawn up.

Cat-Salt, a name given by our salt-workers to a very beautifully granulated kind of common salt. It is formed out of the bitter, or leach-brine, which runs from the salt when taken out of the pan. When they draw out the common salt from the boiling pans, they put it into long wooden troughs, with holes bored at the bottom for the brine to drain out; under these troughs are placed vessels to receive this brine, and across them small sticks to which the cat-salt affixes itself in very large and beautiful crystals. This salt contains some portion of the bitter purging salt, is very sharp and pungent, and is white when powdered, though pellucid in the mass. It is used by some for the table, but the greatest part of what is made of it is used by the makers of hard-soap.
Cat-Silver. See MICA.
