clyster should be composed of three or four ounces of tincture of opium in two quarts of gruel, or warm water. Gibson gave half an ounce of solid opium dissolved in water, as a clyster to a horse in locked jaw, with success. Nourishing clysters are composed of arrow-root, or wheat-flour gruel with sugar, or broth thickened with flour. Tincture of opium is an useful addition to such clysters, especially in locked jaw.—_Blaine._—_White._ COAL, _s._ The common fossil fuel; the cinder of burnt wood, charcoal. COAL-BLACK, _a._ Black in the highest degree. COAT, _s._ The upper garment; the covering of any animal; any tegument. COAT, _v._ To cover; to change the hair. COAT-CARD, _s._ A card having a coat on it; as the king, queen, or knave; now corrupted into _Court-card_. COB, _s._ A sort of sea-fowl; a low but powerful horse; a hack. [Illustration] Perfection is seldom found in any living being; but certain it is, that of all animals in which perfection, or as near to it as their nature will admit, is required, it is in a horse to carry a man or a woman on the road: and were I requested by a friend to purchase a good hack for him, I should consider him to have given me a commission ten times more difficult than if he had requested me to purchase half a dozen hunters. The qualifications of a good hack are so numerous as to be almost disheartening to look for them: he must have good fore legs as well as good hinder ones: he must have perfect feet, a good mouth, not given to start, safe on his legs, gentle in his temper, and quiet to ride on all occasions. A fidgetty hack, however good in his nature, is very unpleasant, and in hot weather insupportable. He is fit for nothing but to ride to covert at the rate of twenty miles in the hour.—_Nimrod._ COBBLE, _v._ To mend any thing coarsely; to do or make any thing clumsily. COBBLE, _s._ A punt used for wild-fowl shooting, fishing, &c. COCHINEAL, _s._ An insect, from which a red colour is extracted. COCK, _s._ The male to the hen; the male of any small bird; the weather-cock that shows the direction of the wind; a spout to let out water or any other liquor at will; the notch of an arrow; the part of a lock of a gun that strikes with the flint; cock-boat, a small boat; a small heap of hay; the form of a hat. _Cock-fighting_ is a sport of great antiquity. It is supposed to have first originated with the Greeks; and that at one period it became so prevalent amongst them, that families of extensive property were reduced thereby to the lowest ebb of fortune. As the Romans were so fond of imitating the Greeks, in their bad as well as good customs, it came to them as a mere gambling sport. According to Herodian, the first cause of contention between the two brothers, Bassianus and Geta, sons of the Emperor Septimus Severus, happened in their youth, about cock-fighting, which they had probably seen in Greece, whither they had often accompanied their father.
