“Here the record of vertical pressure is necessarily absent, since there are no spreading nibs to admit a larger flow of fluid. But the lateral deviations are very pronounced, and — what might not have been expected — in almost every case the position of the pencil may be determined by a more or less continuous line forming one margin of the stroke while the other is a fringe of detached dots and marks comparable roughly to the map of an archipelago and the main coast. These detached spots are evidently the minute bosses and corrugations of the fibrous surface of the paper which have been touched and soiled by the solid point of the writing instrument.”
