After five years of search I have been able to discover but one book in English upon the art of kissing, and that is a very feeble treatise by a savant of York, Pa., Dr. R. McCormick Sturgeon. There may be others, but I have been quite unable to find them. Kissing, for all one hears of it, has not attracted the scientists and literati; one compares its meagre literature with the endless books upon the other phenomena of love, especially divorce and obstetrics. Even Dr. Sturgeon, pioneering bravely, is unable to get beyond a sentimental and trivial view of the thing he vivisects, and so his book is no more than a compendium of mush. His very description of the act of kissing is made up of sonorous gabble about heaving bosoms, red lips, electric sparks and such-like imaginings. What reason have we for believing, as he says, that the lungs are "strongly expanded" during the act? My own casual observation inclines me to hold that the opposite is true, that the lungs are actually collapsed in a pseudo-asthmatic spasm. Again, what is the ground for arguing that the lips are "full, ripe and red?" The real effect of the emotions that accompany kissing is to empty the superficial capillaries and so produce a leaden pallor. As for such salient symptoms as the temperature, the pulse and the rate of respiration, the learned pundit passes them over without a word. Mrs. Elsie Clews Parsons would be a good one to write a sober and accurate treatise upon kissing. Her books upon "The Family" and "Fear and Conventionality" indicate her possession of the right sort of learning. Even better would be a work by Havelock Ellis, say, in three or four volumes. Ellis has devoted his whole life to illuminating the mysteries of sex, and his collection of materials is unsurpassed in the world. Surely there must be an enormous mass of instructive stuff about kissing in his card indexes, letter files, book presses and archives.

Just why the kiss as we know it should have attained to its present popularity in Christendom is probably one of the things past finding out. The Japanese, a very affectionate and sentimental people, do not practise kissing in any form; they regard the act, in fact, with an aversion matching our own aversion to the rubbing of noses. Nor is it in vogue among the Moslems, nor among the Chinese, who countenance it only as between mother and child. Even in parts of Christendom it is girt about by rigid taboos, so that its practise tends to be restricted to a few occasions. Two Frenchmen or Italians, when they meet, kiss each other on both cheeks. One used to see, indeed, many pictures of General Joffre thus bussing the heroes of Verdun; there even appeared in print a story to the effect that one of them objected to the scratching of his moustache. But imagine two Englishmen kissing! Or two Germans! As well imagined the former kissing the latter! Such a display of affection is simply impossible to men of Northern blood; they would die with shame if caught at it. The Englishman, like the American, never kisses if he can help it. He even regards it as bad form to kiss his wife in a railway station, or, in fact, anywhere in sight of a third party. The Latin has no such compunctions. He leaps to the business regardless of place or time; his sole concern is with the lady. Once, in driving from Nice to Monte Carlo along the lower Corniche road, I passed a hundred or so open taxicabs containing man and woman, and fully 75 per cent. of the men had their arms around their companions, and were kissing them. These were not peasants, remember, but well-to-do persons. In England such a scene would have caused a great scandal; in most American States the police would have charged the offenders with drawn revolvers.

The charm of kissing is one of the things I have always wondered at. I do not pretend, of course, that I have never done it; mere politeness forces one to it; there are women who sulk and grow bellicose unless one at least makes the motions of kissing them. But what I mean is that I have never found the act a tenth part as agreeable as poets, the authors of musical comedy librettos, and (on the contrary side) chaperones and the gendarmerie make it out. The physical sensation, far from being pleasant, is intensely uncomfortable—the suspension of respiration, indeed, quickly resolves itself into a feeling of suffocation—and the posture necessitated by the approximation of lips and lips is unfailingly a constrained and ungraceful one. Theoretically, a man kisses a woman perpendicularly, with their eyes, those "windows of the soul," synchronizing exactly. But actually, on account of the incompressibility of the nasal cartilages, he has to incline either his or her head to an angle of at least 60 degrees, and the result is that his right eye gazes insanely at the space between her eyebrows, while his left eye is fixed upon some vague spot behind her. An instantaneous photograph of such a maneuvre, taken at the moment of incidence, would probably turn the stomach of even the most romantic man, and force him, in sheer self-respect, to renounce kissing as he has renounced leap-frog and walking on stilts. Only a woman (for women are quite devoid of aesthetic feeling) could survive so damning a picture.

But the most embarrassing moment, in kissing, does not come during the actual kiss (for at that time the sensation of suffocation drives out all purely psychical feelings), but immediately afterward. What is one to say to the woman then? The occasion obviously demands some sort of remark. One has just received (in theory) a great boon; the silence begins to make itself felt; there stands the fair one, obviously waiting. Is one to thank her? Certainly that would be too transparent a piece of hypocrisy, too flaccid a banality. Is one to tell her that one loves her? Obviously, there is danger in such assurances, and beside, one usually doesn't, and a lie is a lie. Or is one to descend to chatty commonplaces—about the weather, literature, politics, the war? The practical impossibility of solving the problem leads almost inevitably to a blunder far worse than any merely verbal one: one kisses her again, and then again, and so on, and so on. The ultimate result is satiety, repugnance, disgust; even the girl herself gets enough.
