artifices, invented to keep the people in ignorance and superstition,
were detected and punished. Though much good has already resulted from
the use of printing, yet much of what it is capable of still remains to
be accomplished; for its utmost utility is not to be looked for while
there remains any restraint]

persecution under which Printing labours in most of the Catholic
countries in Europe, wherein it still remains subject to the control of
bigotted ecclesiastics, who feel, as being still applicable to

It will be well to familiarize the eye with these different Sizes of
Type, which may easily be done by a little practice, as it will greatly
facilitate the understanding of the various technical details connected
with the Press.

Next to the Size of the Type, the Size of the Page will have to be

by custom, they are yet in practice sufficiently open to variation, to
meet the case of each particular Work. Thus by the Size of the Type, and
Number of Lines, a Work may be either expanded, or compressed, as may be
desired.
