Darwin, as we have seen, has satisfied himself as to the flooding of the eyes. The concomitant movements of hands and feet seem to be common. A more precise account of these movements is given by Ling Roth. The Tasmanians, he tells us, accompanied their loud bursts of laughter with movements of the hands to the head and quick tapping movements of the feet.[158] The loud, deep-chested character of the men’s laughter is sometimes specially noted. A recent visitor to Central Africa regrets that, under European influence, the deep-chested, hearty laughter of men is being replaced by what is known as the “mission giggle” in the younger folk.[159] I have come across, too, one attempt to describe with some exactness the expression of a happy mood when it flows on more quietly. The good spirits of the Andamanese, it appears, show themselves in a sparkling of the eyes, and a wrinkling of the surrounding skin, also in a drawing back of the corners of the mouth which remains partially open.[160] It may be concluded that the facial movements and {228} other changes correspond broadly with what we have seen to be the characteristic expression in the case of the children of civilised races; though differences of racial physique undoubtedly introduce a slight amount of dissimilarity into the expressive movements of laughter.[161] Much of this savage laughter is just the outcome of a “gladsome mind,” a flow of good spirits undisturbed by the thought of care or trouble. This persistent “cheerfulness,” to describe it by our inadequate language, stands their possessors in good stead. The natural gaiety of the Maoris, we are assured, comes to their aid when they encounter hardship. They are full of fun even when short of food on a journey.[162] But the laughter of savages does not appear merely as a general sign of gaiety and rollicking spirits. It has become specialised into the expression of particular mental conditions and attitudes similar to those which are expressed by the laughter of our own children.
