Conglomerate

in geology, pebbles, gravel, or any similar collection of rounded water-worn fragments of rocks, the whole bound together by a silicious, calcareous, or argillaceous cement. It is sometimes called also pudding-stone.

The pebbles, or gravel, have a history before becoming fixed in the conglomerate. By reading that history the geologist is able to trace the direction of currents of water, etc., and recompose lost chapters, or parts of chapters, in the history of the earth.

In anatomy, the conglomerate glands are compound glands, chiefly of the racemose class. Examples - the pancreas, the salivary, lachrymal, and mammary glands, Brunner's glands, and most of the small glands that open into the mouth, the fauces, and the windpipe.
