classification would carry a student past the sense of its unimportance. But here I would rather attempt not to find a formula or a definition for humour, but to discover what it is, like argon, by eliminating other characteristics, until the evasive quality alone remains. It lies deep in nature. The peevish mouth and the fallen eye of the plaice, the helpless rotundity of the sunfish, the mournful gape and rolling glance of the goldfish, the furious and ineffective mien of the barndoor fowl, the wild grotesqueness of the babyroussa and the wart-hog, the crafty solemn eye of the parrot,--if such things as these do not testify to a sense of humour in the Creative Spirit, it is hard to account for the fact that in man a perception is implanted which should find such sights pleasurably entertaining from infancy upwards. I suppose the root of the matter is that, insensibly comparing these facial attributes with the expression of humanity, one credits the animals above described with the emotions which they do not necessarily feel; yet even so it is hard to analyse, because grotesque exaggerations of human features, which are perfectly normal and natural, seem calculated to move the amusement of humanity quite instinctively. A child is apt to be alarmed at first by what is grotesque, and, when once reassured, to find in it a matter of delight. Perhaps the mistake we make is to credit the Creative Spirit with human emotions; but, on the other hand, it is difficult to see how complex emotions, not connected with any material needs and impulses, can be found existing in organisms, unless the same emotions exist in the mind of their Creator. If the thrush bursts into song on the bare bush at evening, if the child smiles to see the bulging hairy cactus, there must be, I think, something joyful and smiling at the heart, the inmost cell of nature, loving beauty and laughter; indeed, beauty and mirth must be the natural signs of health and content. And then there strike in upon the mind two thoughts. Is, perhaps, the basis of humour a kind of selfish security? Does one primarily laugh at all that is odd, grotesque, broken, ill at ease, fantastic, because such things heighten the sense of one's own health and security? I do not mean that this is the flower of modern humour; but is it not, perhaps, the root? Is not the basis of laughter perhaps the purely childish and selfish impulse to delight, not in the sufferings of others, but in the sense which all distorted things minister to one--that one is temporarily, at least, more blest than they? A child does not laugh for pure happiness--when it is happiest, it is most grave and solemn; but when the sense of its health and soundness is brought home to it poignantly, then it laughs aloud, just as it laughs at the pleasant pain of being tickled, because the tiny uneasiness throws into relief its sense of secure well-being.
