egg, + λέμμα, peel, skin.] brane of an ovum. oölite (o'ō-lit), n. and a. + λίθος, a stone.] I. n. A granular limeston: [ Sheridan, School for Scandal, iv. 1. oop (up), v. t. [A dial. form of whip.] 1. Το bind round with thread or cord, whip: as, to ly spherical, and made up of concentric coats of carbonate of lime formed around a minute nucleus, which is usually a grain of sand: so called from the resemblance of the rock to the roe of a fish. The term oõlite gave the name to important series of fo iliferous rocks-the Oölite of English and the Jura ic of Continental and American geologists. Oölitic as thus employed is, however, obsolescent in England. The series was called oölitic from the fact that it is largely made up of limestone having that peculiar structure. The following are the generally recognized subdivisions of the Oolitic or Jura ic system in England: the Upper or Portland Oölite, comprising the Purbeckian, Portland i an, and Kimmeridgian; the Middle or Oxford Oölite, comprising the Cor all i an and Oxford i an; and the Lower or Bath Oolite, comprising the Great Oölite group, the Fuller's Earth, and the Inferior Oölite. Beneath this comes the Lias. See Jura ic. II. a. Same as oölitic.
