of mechanical effects, glimpses suggested by man's complex actions, no longer merely by his gestures. We instinctively feel that the usual devices of comedy, the periodical repetition of a word or a scene, the systematic inversion of the parts, the geometrical development of a farcical misunderstanding, and many other stage contrivances, must derive their comic force from the same source,—the art of the playwright probably consisting in setting before us an obvious clockwork arrangement of human events, while carefully preserving an outward aspect of probability and thereby retaining something of the suppleness of life. But we must not forestall results which will be duly disclosed in the course of our analysis.
Before going further, let us halt a moment and glance around. As we hinted at the outset of this study, it would be idle to attempt to derive every comic effect from one simple formula. The formula exists well enough in a certain sense, but its development does not follow a straightforward course. What I mean
