is the em of the size pica; the small one , one fourth the size (one half the height and breadth), is the em of the size nonpareil, the one here used. The em is the unit of measurement in calculating the amount of type in a piece of work, as a page, a column, or a book, the standard of reckoning being 1,000; thus, this page or this book contains so many thousand, or so many thousand and hundred, ems. In the United States it is also the unit in calculating the amount of work done by a compositor, while the en is generally used for that purpose in Great Britain. - In colloquial speech, the objective plural of he, she, it: equivalent to them.
