Horehound , (Ang. Sax. hora, hoary, and hune, honey, a name originally applied to some related honey-bearing plant), the marrubium vulgare (Linn.), a plant of the natural order labiatoe. It is a native of Europe, now common in the older portions of this country in waste places and by roadsides. It is a herbaceous perennial, with four-angled stems 12 or 18 in. high, which, as well as the roughish opposite leaves, are whitish downy ; it bears in July and August white flowers in crowded axillary whorls. The herb, like many others of the same order, is remarkable for its aromatic odor and tonic properties, so that it is a favorite domestic medicine, being used in the form of a decoction, in a sirup, and in candy, and especially for colds and affections of the lungs. Its bitter taste is imparted to water and to alcohol. Its prolonged use is apt to derange the stomach.

Horites , the aboriginal inhabitants of Mount Seir. It is thought that they formed part of the race to which the Zuzims, the Rephaim, and Emim belonged, and inhabited Mount Seir before the Canaanites took possession of Palestine. Their name, which is derived from Hori, the grandson of Seir (Gen. xxxvi. 22), was descriptive of their habits as cave-dwellers. Their excavated dwellings are still found in hundreds in the sandstone cliffs and mountains of Edom, and especially in Petra. They are cut in the natural rock, some of them having rude arches carved over the doorways; and some are inhabited now, as they have been apparently by generation after generation. The genealogy of the Horites is twice given in the Scriptures, which say that they were divided into seven tribes. They were among the nations smitten by the kings of the east in the time of Abraham, and were superseded, or perhaps supplanted and absorbed, by the Edom-ites, who adopted their habits.
Horizon , (Gr. from to bound or define), the line that apparently separates earth and sky. In astronomy, the apparent horizon is a place tangent to the earth at the observer, and the real horizon is a plane through the centre of the earth parallel to the apparent horizon. The artificial horizon is a horizontal mirror, usually the surface of a basin of mercury. Half the angular distance between a star and its image seen in the artificial horizon is equal to the altitude of the star above the real horizon.
