History. In the north of the island ruined cities have been discovered, bringing to light rock-hewn temples, cave temples, relic shrines which almost compare with the pyramids of Egypt and gigantic water-tanks on which an immense amount of labor must have been bestowed. The Portuguese settled on the island in 1517, but were driven out by the Dutch in 1658, who were in turn conquered by the British, in 1796. The chief town is Colombo (population, 158,228). Population, chiefly Singhalese and Tamils, 3,592,397.

Chalazogamy (k&l'a-zog'a-mZ), in plants. In ordinary angiosperms the pollen tube, having passed through the style, enters the micropyle of the ovule and so reaches the egg. In certain dicotyledons, as walnut, birch, alder, etc.,-it has been found that the pollen-tube does not enter the micropyle, the natural passageway to the egg, but penetrates directly through the external parts of the ovule and burrows its way to the egg from the side or from beneath. The name has been given from the fact that the basal region of the ovule is known as the chalaza, which is at the opposite end of the ovule from the micropyle. The habit is a curious one, and its significance is not clear.
Chalcedony (kal-sed'o-ny), a beautiful mineral. It is a variety of quartz, with a mixture of opal. It was found abundantly near Chalcedon, in Bithynia, which gave it its name. It is found lining or wholly filling cavities in old rocks, like the basalt rock of Scotland, Iceland, etc. Chalcedony composes the whole or main part of many agates. It is generally translucent, has a waxy luster and is usually white or bluish white; sometimes reddish or milk white; more rarely gray, blue, green, yellow, brown or black. Chalcedony is much used in jewelry for brooches, necklaces and ornaments of all sorts; and large pieces are often made into little boxes, cups, etc. The people of olden times prized it highly, and many beautiful engraved specimens can be seen in museums. Petrified plants are sometimes found in chalcedony, in which they seem to have been incased while it was forming. Sometimes a specimen with a little water inside is discovered.
