GALAXY

A broad and irregular zone of stars that surround the heavens, so distant that their united light gives but an indistinct and undefined whitishne to the whole appearance — whence its name. See Gaiiaxy. MILL. (Yunanca köken — orijinale bakınız.) This term seems to have signified originally an engine for grinding corn, but it is now used in-a general sense to denote a great variety of machines, whose action depends chiefly on circular motion. The particular purpose is usually indicated by a prefix; thus, bark-mill, cotton-mill, flour-mill, oil-mill, saw-mill, spinning-mill, . The machinery by which it is nece ary to accomplish the ultimate objects of the mill must obviously vary almost indefinitely. Many voluminous works on this subject have been published, as well as separate accounts of particular structures. See Brewster's edition of Fergiison's Lectures; Gray^s Experienced Millwright; Buchanan on Millwork, by Tredgold; Banks on Mills; The Repository of Arts, . A catalogue of the principal works on the subject of mills is given in Gregory's Mechanics, vol.ii. MILL, BARKERS* Sc^ Centrifugal Machine. [s. 756]
