So far we have been concerned mainly with the tactile kiss, which is sometimes supposed to have arisen in remote times to the east of the Mediterranean--where the vassal kissed his suzerain and where the kiss of love was known, as we learn from the Songs of Songs, to the Hebrews--and has now conquered nearly the whole of Europe. But over a much larger part of the world and even in one corner of Europe (Lapland, as well as among the Russian Yakuts) a different kind of salutation rules, the olfactory kiss. This varies in form in different regions and sometimes simulates a tactile kiss, but, as it exists in a typical form in China, where it has been carefully studied by d'Enjoy, it may be said to be made up of three phases: (1) the nose is applied to the cheek of the beloved person; (2) there is a long nasal inspiration accompanied by lowering of the eyelids; (3) there is a slight smacking of the lips without the application of the mouth to the embraced cheek. The whole process, d'Enjoy considers, is founded on sexual desire and the desire for food, smell being the sense employed in both fields. In the form described by d'Enjoy, we have the Mongolian variety of the olfactory kiss. The Chinese regard the European kiss as odious, suggesting voracious cannibals, and yellow mothers in the French colonies still frighten children by threatening to give them the white man's kiss. Their own kiss the Chinese regard as exclusively voluptuous; it is only befitting as between lovers, and not only do fathers refrain from kissing their children except when very young, but even the mothers only give their children a rare and furtive kiss. Among some of the hill-tribes of south-east India the olfactory kiss is found, the nose being applied to the cheek during salutation with a strong inhalation; instead of saying "Kiss me," they here say "Smell me." The Tamils, I am told by a medical correspondent in Ceylon, do not kiss during coitus, but rub noses and also lick each other's mouth and tongue. The olfactory kiss is known in Africa; thus, on the Gambia in inland Africa when a man salutes a woman he takes her hand and places it to his nose, twice smelling the back of it. Among the Jekris of the Niger coast mothers rub their babies with their cheeks or mouths, but they do not kiss them, nor do lovers kiss, though they squeeze, cuddle, and embrace.[213] Among the Swahilis a smell kiss exists, and very young boys are taught to raise their clothes before women visitors, who thereupon playfully smell the penis; the child who does this is said to "give tobacco."[214] Kissing of any kind appears to be unknown to the Indians throughout a large part of America: Im Thurn states that it is unknown to the Indians of Guiana, and at the other end of South America Hyades and Deniker state that it is unknown to the Fuegians. In Forth America the olfactory kiss is known to the Eskimo, and has been noted among some Indian tribes, as the Blackfeet. It is also known in Polynesia.
