Page 107 - If the cohesive force oF(Fig. 117) is strong in comparison with the adhesive force oE, the resultant oR will fall to the right of the vertical, in which case the liquid must be depressed about o. Whether, then, a liquid will rise against a solid wall or be depressed by it, will depend only on the relative strengths of the adhesion of the wall for the liquid and the cohesion of the liquid for itself.
