“ Attention has been called to the similarity existing between a man's handwriting and the manner in which he walks or gesticulates. It has been claimed that age and sex and profession leave their impress upon writing, that the pencraft of the painter mirrors minutely the grace and distinction that marks the sweep of his brush across the canvas. Carried out boldly such speculations venture even the claim that the handwriting of any individual would be found to resemble the characteristic tracings shown by his pulse and respiration and fatigue curves. ”
