WARING V. JOHNSON. 507 �movement at ail of any check leaf , and without any move- ment of any stub leaf in any direction, except to the left or right towards or from the place of binding, like turnin^ the leaves of any ordinary bound book. �On the question of infringement the first question is as to the proper construction of the first claim of the plaintiff's re-issue. On this subject, as well as on the question of nov- elty, several alleged prior inventions are introduced.
