Note 75 — Early Typography. CHAPTER III.

Eight great inventions may be enumerated in the history of Typography. These are, first, the block books; second, the separable types; third, the printing-press; fourth, type-founding; fifth, stereotyping, (taking plaster moulds of whole pages of type, and from them castings in solid metal plates); sixth, composition inking rollers; seventh, cylindrical printing machines, to be worked by steam-power; and eighth, steam type-setting machines. As the four last are of modern date, they do not come within the scope of the present work.
