GRADATION OF TYPES.

The following specimen shows the proportion which one size of type bears to another in width; but it is necessary to observe that it must be taken with certain limitations, because each founder has letter of every size that will either drive out or get in with others of the same body, some faces being more extended and others being more condensed than the standard width of type. The scale contains thirteen sizes in order of gradation, viz., Great Primer, English, Pica, Small Pica, Long Primer, Bourgeois, Brevier, Minion, Nonpareil, Agate, Pearl, Diamond, and Brilliant.
