This Quality manifests outer form on the centre-line of the back part of the top head, just above Self-Esteem. The location may be ascertained by holding the head erect, drawing an imaginary line upward from the opening of the ears straight to the top of the head to the middle-line or centre of the top of the head--the location is at this last-point. It is usually quite prominent, and in many men unusually large. When fully developed it gives a "tallness" to the head from the opening of the ears to top of head. When it is weak, there is apt to be a flatness or even a depression at the point of its location. It also manifests in a "stiff upper lip," that is a firm upper lip, the latter often being longer than ordinarily. A certain stiffness of the upper-lip is often noticed when Firmness is habitually asserted, or in cases when the Quality is temporarily called into play. The term "stiff upper lip" is more than a mere figurative expression. Combe says of this Quality: "When this organ predominates it gives a peculiar hardness to the manner, a stiffness and uprightness to the gait, with a forcible and emphatic tone to the voice." CONTINUITY. This propensity manifests in a strong tendency to "stick-to" a thing once begun, until it is finished; a disinclination for change; a habit of patient work and thought; a desire to do but one thing at a time; etc. It is difficult to interest these people in _new_ things--they hold fast to the _old_. They are naturally conservative and are averse to "new-fangled" things. They are plodders and steady workers, and run on like a clock when once wound up. They are apt to possess the power of long and continued concentration upon anything which attracts their attention, although it is difficult to attract their attention to an entirely new thing. Prof. Sizer says: "Firmness gives a stiff, determined fortitude, decision of character; it serves to brace up the other faculties to the work in hand.... Firmness gives determination and obstinacy of purpose, while _Continuity_ gives a patient, perfecting, plodding application. Of two stone-cutters with equal Firmness, they will be alike thorough and persevering, but if one has large Continuity he prefers to use the drill in one place for hours, while the other with small Continuity craves variety, and prefers to use the chisel in cutting and dressing the entire surface of the stone."
