The first line of a paragraph is usually indented an em quadrate; but when the matter is leaded or the measure is wide, an em and en, or two or even three ems may be used. An em quadrate is the proper space after a full-point when it terminates a sentence in a paragraph.
En quadrates are generally used after the semicolon, colon, &c., and sometimes after an overhanging letter. They are useful in spacing.
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 They are being superseded, however, by
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.
