6. 2. A leveling-instrument in which water is employed instead of mercury or spirit of wine. It consists in the about feet long bent at right angles at each end, with small short soldered on it at center, aid of which it can be fixed upon some kind of a support or tripod. In the bent ends of the long tube are inserted two small gla vials with their bot toms cut off. Enough water is then poured in to about half fill the bottles when the instrument is level. By sighting acro the surface of the water a level-line is got. The extreme cheapne and portability of this level make it serviceable sometimes, although it gives but a rough approximation to accuracy as compared with the best kind of spirit-level. water-lily (water-lil i), n. [ watir - lil i , watyr -lyly; water + lily .] 1. A plant of the genus Castalia (Nymphæa), which contains about 25 species distributed nearly throughout the world, but most freely in the northern hemisphere and the tropics. They are aquatic plants with a perennial rootstock, orbicular floating leaves, and large flowers, single on long scapes riding on the surface of the water. The flowers have numerous petals of a deli cate texture, forning when expanded nearly a hemisphere -white, blue, red, or yellow. Several white are the most familiar.

In the interior United States is found C. ( N. ) reniform is , with considerably larger leaves and flowers, scentle or slightly apple-scented, and always white-the rootstock bearing numerous self-detaching tubers. The golden water-lily, C. ( N. ) flava , of Florida, which long escaped the notice of botanists, is a locally abundant species of moderate dimensions, with yellow flowers. C. mystic a ( N. Lotus ), the specific Egyptian water-lily, with white, pink, or red flowers, and C. scut i folia (N. cærule a ), the blue water-lily, also of Egypt, are named among the lotuses. C. ( N. ) thermal is is a rare species occurring in warm springs in Hungary, and called Hunga rian lotus. The Australian water-lily, C. C. ( N. ) gigantea , has the leaves in the larger specimens 18 inches broad, the flowers a foot broad with over 200 stamens, the petals blue, purple, pink, or rarely white.
