A character cast in metal thus marked }. The compositor is to have these cast of several breadths, viz. to several number of lines of a designed body (most commonly of Pica body) that they may hook in or brace so many lines as his copy may show him. — M.
It is used in poetry at the end of a triplet, or three lines which have the same rhyme.
Braces are also used to connect a number of words with one common term, and are introduced to prevent a repetition in writing or printing. — Murray.
Braces are cast to different bodies as high as English; and braces on Long Primer are now cast from three to eight ems in length, which look much neater than the old fashion of middles and corners, filled up with metal rules.
The founders in casting long Braces always make the swell in the face of them proportionably thick to their length, so that in using them with small letter they look heavy and clumsy; I would recommend that long Braces should be cast to a small body, not larger than Brevier, and the faces of all the lengths uniform, so that when there happens to be a range of them of different lengths in a page they might harmonize, and not make such an incongruous appearance as they now do. When Braces are wanted longer than those already cast, I would not use middles and corners, but make them of Brass Rule in one continued piece, which has a better appearance than when they are joined, and which may be made with a file in a neat manner by any clever compositor.
