Rh of an inch diameter, on the side of the type, was firmly depressed in the metal, but did not perforate it. As this type had no nick on the body, it is apparent that the circular mark was cast there to guide the compositor. When the type was put in the stick with the mark facing outward, the compositor knew, without looking at the face, that it was rightly placed. There is no groove at the foot Duverger says that the early types had no jet or breaking-piece; that the superfluous metal was cut off, and the type made of proper height by sawing. These details may seem trifling, but they are of importance: they show that, in the more important features, the types of the early printers closely resembled ours.

There is a disagreement among bibliographers about the quantity of types ordinarily cast for a font by the early printers. Some, judging from appearances which show that one page only was printed at an impression, say that they cast types for two or three pages only; others maintain that they must have had very large fonts. That the latter view is correct seems fully established after a survey of the books known to have been printed by Zell, Koburger, Leeu, and others. It would have been impossible to print these books in the short period in which we know they were done, if the printer had not been provided with abundance of types. As the types were made in the printing office, by a quick method, from an alloy which could be used repeatedly for the same purpose, the supply was rarely limited by fear of expense.

The trades of compositor and pressman, and possibly that of type-caster, were kept about as distinct then as they are now. There were more compositors than pressmen, and the
