[Eng. urox(anic); -il, -yl. ] [UROXANIC-ANHYDRIDE.] u-rox-in, 8. [Eng. urox ( anic ); -in.] [ALLOXAN TIN.] ür-pěth-ite, subst. [After the Urpeth Colliery, where found; suff. -ite ( Min.).] Min .: A member of the Paraffin group of hydrocarbons; soft, like tallow; specific gravity, 0.885; color, yellowish-brown. An analysis yielded Johnson: Carbon, 85-83; hydrogen, 14-17=100. Separated from the ozocerite of the Urpeth Colliery by its ready solubility in cold ether. ŭr-rỹ, s. [Cf. Gael. uirlach =mold, dust.] A sort ( Prov.) of blue or black clay, lying near a vein of coal. "In the coal-mines they dig a blue or black clay, that lies near the coal, commonly called urry , which is an unripe coal, and is very proper for hot lands, especially pasture ground."-Mortimer: Husbandry. Ur-są, s. [Lat.=(1) a she bear, (2) a constellation.] Astron.: The Bear; the first word in the name of two constellations. Ursa Major, s . Astron.: The Great Bear. The most conspicuous of the twenty ancient northern constellations, its seven leading stars attracting notice all the more conspicuously that there is a certain absence of visible heavenly bodies in the adjacent parts of the sky. The Semitic conception of the constellation was that it resembled a bier with mourners walking behind. [ARCTURUS, BENETNASCH]), and it has sometimes been called specifically Lazarus' bier, bench; go, gem; thin, this; ursine Mary Magdalene, the mourners. It is much like a plow, and is often called the Plow, the rectangle constituting its body, and the three projecting stars its handle. To other minds it suggests a vehicle, whence it has been called the Car of David, and sometimes Charles' Wain, or Wagon. The four stars standing together are the wheels, and the three behind are the shaft. Another name is the Dipper. But astronomers cling to the old cla ical conception of a bear, of which the four stars, Alpha, Beta, Gamma, Delta, Ur æ Major is, are the hind quarter, and the three the tail. The remaining portions of the animal are marked out by sundry small stars of the third and fourth magnitude. The Bear was supposed to require a ward or keeper. [ARCTURUS. The Arabs gave the seven conspicuous IMG:content-0342.jpg:[graphic][subsumed][merged small] stars names, some of which are still in use. They called Alpha Ur e Major is or Dubhe; Merak; Gamma, Phecda; Delta, Megrez; Epsilon, Alioth; Zeta, Mizar; and Eta, Alcaid, or Benetnasch. The first two are called Pointers, because a line drawn from Beta through Alpha and continued for about five times as far as the distance between them will reach the pole-star. Ursa Major is bounded on the north by Draco and Camelopard a lis, on the south by Leo Minor, on the east by Canes Venatic i, and on the west by Lynx and Camelopard a lis. Of the seven stars six are of the second magnitude, the remaining one (Delta) being at present between the third and fourth magnitude. Mizar (Zeta) is a double star. Powerful telescopes show that the Great Bear is made up of many you sand other stars. Ursa Minor, s . Astronomy: The Little Bear; one of the twenty ancient northern constellations, bounded by Draco, Camelopard a lis, Ca iopeia and Perseus. Its contour is marked out by seven stars. The curvature of the tail is in the contrary direction to that of the Great Bear; and at its tip is a star of the second magnitude, Alpha Urse Minor is, called Polar is, or the Pole Star (q. v.), midway between Ca iopeia and the Great Bear. Next in brightne are Beta Urse Minor is, called by the Arabs Kokab, and Gamma Urse Minor is. The two are sometimes designated the Guards of the Pole, or simply the Guards. Kokab is of the second, and the other of the third. The remaining stars are smaller. ür'-sal, s. [URSUS.] Zool.: The Ursine-seal. ( Ann andale .) ür-si-dæ, s. pl. [Mod. Lat. urs ( us ); Lat. fem. pl. adj. suff. -idœ.] 1. Zool .: Bears; a family of the Carnivora, group Arc to idea, or, in older cla ifications, Plant i grad a (q. v.). Claws, five on each foot, large, strong, and curved, non-retractile; tongue smooth; ears small, erect, and rounded; tail short; nose forming a movable truncated snout; cæcum absent. Though ranged with the Carnivora, many of the Urside live entirely or partially on vegetable diet, and their teeth are modified accordingly. They are widely distributed, but are entirely absent from the Australian and Ethiopian regions, and only one species, Ursus (or Tremarctos ) ornatus , from the Andes of Peru and Chili. Wallace reckons fifteen species, which have been grouped into as many as five genera (Ursus, Thala arctos, Helarctos, Melursus or Proc hilus, and Tremarctos); Mivart ( Proc . Zool. Soc . 1885, p. 395) makes two genera (Ursus and Melursus); and Prof. Flower ( Encyc . Brit . ed. 9th, art. Mammal i a ) includes Ailuropus, an annectant form connecting Ursus with Ailurus (q. v.). 2. Palæont .: The family appears first in the Miocene.
