Ent. The proof of a page displaying such conditions often causes
the author, unlearned in printers' methods, much perturbation of mind and unnecessary fear that his book is going to be printed with these defects. These should in reality be no cause for worry, since by a later operation,
that of "locking-up" the "form" in which the pages will be placed before they are sent to the electrotyping department,
the types readily
and correctly adjust themselves. Proofs of these twine-bound

pages are
taken on a hand-press, passed to the reviser for comparison with the galley-proofs
returned by the author, and if the latter has expressed a wish to see a second revise of the proofs, they are again sent to him. For such a "second revise" and any further revises an extra charge is made. The proofs to which an author is regularly entitled are a duplicate set
