If you have not a certificate to produce at the time it is called for, your Christian and surnames, and place of abode, may be demanded by any assessor, &c. &c., (as before mentioned) and the penalty for refusing them, or giving a false name, is 20_l._ CERULEAN, _a._ Blue, sky-coloured. CHAD, _s._ A sort of fish. CHAFFINCH, _s._ A bird so called, because it delights in chaff. This bird is rather less than the sparrow. The bill is bluish; irides hazel; the forehead black; crown of the head, back part, and sides of the neck, bluish ash-colour; the cheeks, under side of the neck, and breast, dull pink; back, chestnut-brown; rump greenish; belly, white, tinged with pink; the bastard wing and coverts of the primary quills are black; those of the secondary tipped with white; the smaller coverts black and greyish, on which is a spot of white; the quill-feathers dusky, slightly edged with greenish yellow on the outer webs, marked with white on both webs at the base; tail dusky; the exterior feather is obliquely marked with white, taking in the whole of the outer web, the next is tipped with white; legs dusky. The female is of a dull green above; the breast and belly of a brown or dirty white; the wings have the same markings as the male, but less brilliant. This bird makes a most elegant nest of green moss, curiously studded with lichen, interwoven with wool, and lined with feathers and hair. It builds against the side of a tree, particularly in ivy, or in some forked branch of a bush; but particularly in apple trees overgrown with moss and lichen, and, like many other birds, adapts the materials of its nest to the surrounding colour; an instinct of no small importance.—_Bewick._ CHAIN, _s._ A series of links fastened one within another; a bond, a manacle; a fetter. CHAISE, _s._ A carriage either of pleasure or expedition. CHALDRON, or CHAUDRON, _s._ A dry English measure of coals, consisting of thirty-six bushels heaped up. The chaldron should weigh two thousand pounds. CHALK, _s._ A white fossil, usually reckoned a stone, but by some ranked among the boles. CHALYBEATE, _a._ Impregnated with iron or steel. CHAMBEL OF A HORSE, _s._ The joint or bending of the upper part of the hind leg. CHAMOIS, _s._ An animal of the goat kind, the skin of which made into leather is called _Shammy_. The chamois is a little larger than a goat, but much superior in power and agility; the strongest man could not hold one of a month old; they bound from precipice to precipice to a prodigious distance, gaining the loftiest summits, and precipitating themselves from the steepest rocks without fear. The chase of this animal occupies a great part of the mountainous population, and many perish annually in the hazardous pursuit.
