Em and en quadrates, and figures as well, should be entirely exact and uniform in body, as even a trifling variation will be apparent when they are arranged in table or figure-work; and no ingenuity on the part of a compositor can rectify the zigzag appearance caused by irregular types. The inconvenience arising from founts of the same body not agreeing in depth is great, where the quadrates, through necessity, are sometimes mixed. The founts cast by MacKellar, Smiths & Jordan are not liable to this charge, as their moulds for all regular type of a specific size harmonize perfectly, and the quadrates and spaces work together. QUOTATIONS. Quotations are large blank type used for filling up considerable spaces at the beginning or end of a chapter, and also for job-work. They are cast to two sizes, and are called broad and narrow. They vary in size according to the standard of the foundry where they are cast. They are being superseded, however, by [Illustration: LABOUR-SAVING QUOTATION FURNITURE.] This is cast with great accuracy to Pica, of assorted widths and lengths; and, as its name imports, it serves not only for quotations in general job-work, but also for furniture. [Illustration: STANDARD METAL FURNITURE.] Owing to the large assortment of sizes contained in this furniture, it is useful for blanking out all varieties of work, from the card or circular to the large hand-bill or poster. As the above metal furnitures are not liable to warp or shrink, they form a highly economical substitute for wooden reglet. [Illustration: HOLLOW QUADRATES] Answer many of the purposes of quotations, but are principally useful as frames or miniature chases for circular or oval jobs. The sizes are graduated from 5 × 8 to 12 × 18 Pica ems. [Illustration: CIRCULAR QUADRATES.] These are made of various sizes, so as to form circles or parts of circles from one to twenty-four inches in diameter. Each piece is exactly one-eighth of a full circle, and, when combined with similar pieces, will form quarter, half, three-quarter, and full circles. By reversing the combination of some of the pieces, serpentine and eccentric curves may be made of any length or depth. There are two kinds: _inner quadrates_, with convex surface, and _outer quadrates_, with concave surface. The curved line is produced by placing the convex and concave surfaces parallel to each other, so that when locked up firmly they hold the type inserted between them. The other sides of the quadrates are flat and right-angled, to allow a close introduction of type, and an easy justification with common quadrates.
