CASE (Fr. cusses CniSSC, Catalan eapsa, Portug. enixa, from Lat. eupsa, box, from cupric, to take). A receptacle for type used in printing, which is divided into compartments or 'boxes,' each of which contains type of one character or 'fetter. A pair of eases consists of an upper and a lower ease: the upper one contains the capi tals. small capitals and some other letters that are only occasionally required; the lower one holding the small letters. figure,. spaces. and most of the points. The places assigned to the
several letters of the alphabet in the boxes of the ease are not the same in all print ing,-ofliees, but the differences are few. The dif ferent sizes of the boxes in the lower ease depend neon the comparative frequency with which the several letters occur in composition. and the position in the case allotted to each letter is such as to a tr,,rd the greatest facility in com posing. The letter e, which is most used in tire English language. has a box much larger than any of the other compartments, and is placed directly in front of the compositor. In the upper ease the boxes are of uniform size, and the let ters are placed in alphabetical order, the com paratively rare occurrence of capitals rendering it immaterial which letter is nearest the com positor's hand.
