_Novelty as related to Wit._--How much novelty and suddenness add to the effect of wit, every one knows. A story however witty, once heard, loses its freshness and zest, and, often repeated, becomes not merely uninteresting, but irksome, and at length intolerable. In the same manner, and for the same reason, a witticism which we know to have been premeditated produces little effect, as compared with the same thing said in sudden repartee, and on the spur of the moment. That a man should have studied out some curious relations and combinations of things in his closet, does not surprise us so much, as that he should happen to conceive of these relations at the very moment when they would meet the exigency of the occasion. The epithets which we most commonly apply to any witty production or facetious remark, indicate the same thing; we call it lively, fresh, sparkling, full of vivacity and zest--terms borrowed, perhaps, from the choicer wines, which will not bear exposure but lose their flavor and life when once brought to the air. _Even the Incongruous not always ludicrous._--We come to this result, then, in our own attempted analysis, that the incongruity of the ideas or objects brought into relation with each other constitutes the essential characteristic, the invariable element of the ludicrous, the effect being always greatly heightened by the surprise we feel at the novel and unexpected combinations thus presented. It must be remarked, however, that even the incongruous and unexpected fail to awaken the sense of the ludicrous, when the object or event contemplated is of such a nature as to give rise to other and more serious emotions. When the occurrence, however novel and surprising in itself, or even ludicrous, is of such a nature as to endanger the life, or seriously injure the well-being of ourselves or of others, in the one case fear, in the other compassion, are at once awakened, and all sense of the ludicrous is completely at an end. The graver passion is at variance with the lighter, and banishes it from the mind. Should we see a well dressed and portly man, of some pretension and bearing, accidentally lose his footing and sprawl ingloriously in the gutter, our first impulse undoubtedly would be to laugh. The incongruity of his present position and appearance with his general neatness of person and dignity of manner would appeal strongly to the sense of the ridiculous. Should we learn, however, that in the fall he had broken his leg, or otherwise seriously injured himself, our mirthfulness at once gives place to pity.
