LUNULÆ. (Lunules, Fr.) In geometry a half moon or crescent, which is made by the arcs of two intersecting circles. If you inscribe a triangle-rectangle within a half circle, the diameter of which becomes the hypothenuse; and if upon each side that compresses the right angle, as its diameter, you describe a half circle, the space in shape of a half moon, closed in by the circumference of each of these two circles, and by a part of the circumference of the great half circle, will form the figure called Lunula.
LUTTE, Fr. Struggle. An exercise of the body, which consists in a full exertion of all its muscular powers to overcome another body, that resists with equal force and pertinacity.
