it seems to us that it should be brought forward that ulcers which consist of a somewhat angular figure reach a scar more quickly, because the healthy parts are closer to one another in the place where the angular ulcer was most prominent. For healthy parts do not unite into a scar with equal ease in just any way. For it is agreed that ulcers that have healthy parts closer to them, and less distant, are healed more easily. In round ulcers, however, the healthy parts are equally distant from one another on all sides, and this is much more so than in an angular figure. For example, if we take two points in a circle at a smaller distance and join them with a straight line, and then soon do the same in a triangle or another angular figure, namely by joining two points from either side of the angle through a straight line, a larger straight line will be found in the circle. Likewise, in round and angu-
