Mark the fronts of the charts with a pin, a thumbtack, a ring, etc, in such a way that the robber making such marks can say later by feeling the ranks of the charts. Such marks are applied to the surface of the charts and do not tear the charts, add simply the impressions which can be felt back, in opposition to the nailing (see the nail), which puts marks in the edges of the charts. Punch or blister also called. It is the opposite of the puncture, in which the robber marks the backs of the charts.
