Monteiro, in a passage previously quoted, says that in all the long years he has been in Africa he has “never seen a negro put his arm round a woman’s waist, or give or receive any caress whatever that would indicate the slightest loving regard or affection on either side.” Considering the general obtuseness of a savage’s nerves, it is no wonder that the subtle thrill of a kiss should be unknown to him. In many cases, moreover, Kissing is rendered physically impossible by the habit indulged in of mutilating and enlarging the lips. For instance, Schweinfurth, in his _Heart of Africa_, says that among the Bongo women “the lower lip is extended horizontally till it projects far beyond the upper, which is also bored and fitted with a copper plate or nail, and now and then by a little ring, and sometimes by a bit of straw, about as thick as a lucifer match.” Many other similar cases could be cited. Evidently, under these circumstances, kissing would prove a snare and a delusion. THE ORIGIN OF KISSING is a topic on which doctors disagree, the opinions of Darwin and Mr. Spencer in particular differing as widely as their views regarding the origin of music. Mr. Spencer traces the primitive delight in osculation to the gustatory sense, Darwin to contact. “Obviously,” says Mr. Spencer, "the billing of doves or pigeons, and the like action of love-birds, indicates an affection which is gratified by the gustatory sensation. No act of this kind on the part of an inferior creature, as of a cow licking a calf, can have any other origin than the direct prompting of a desire which gains by the act satisfaction; and in such a case the satisfaction is that which vivid perception of offspring gives to the maternal yearning. In some animals like acts arise from other forms of affection. Licking the hand, or, where it is accessible, the face, is a common display of attachment on a dog’s part; and when we remember how keen must be the olfactory sense by which a dog traces his master, we cannot doubt that to his gustatory sense, too, there is yielded some impression—an impression associated with those pleasures of affection which his master’s presence gives. “The inference that kissing, as a mark of fondness in the human race, has a kindred origin, is sufficiently probable. Though kissing is not universal—though the negro races do not understand it, and though, as we have seen, there are cases where sniffing replaces it—yet, being common to unlikely and widely-dispersed peoples, we may conclude that it originated in the same manner as the analogous action among lower creatures.... From kissing as a natural sign of affection, there is derived the kissing which, as a means of simulating affection, gratifies those who are kissed; and, by gratifying them, propitiates them. Hence an obvious root for the kissing of feet, hands, garments, as a part of ceremonial.”
