Once the threshold is crossed emotion comes to the aid of perception. That is to say, the blind, almost irresistible mating impulse, now fortuitously relieved from the contrary pressure of active disgusts, fortifies itself by manufacturing illusions. The lover sees with an eye that is both opaque and out of focus. Thus he begins the familiar process of editing and improving his girl. Features and characteristics that, observed in cold blood, might have quickly aroused his most active disgust are now seen through a rose-tinted fog, like drabs in a musical comedy. The lover ends by being almost anæsthetic to disgust. While the spell lasts his lady could shave her head or take to rubbing snuff, or scratch her leg at a communion service, or smear her hair with bear's grease, and yet not disgust him. Here the paralysis of the faculties is again chiefly physical--a matter of obscure secretions, of shifting pressure, of metabolism. Nature is at her tricks. The fever of love is upon its victim. His guard down, he is little more than a pathetic automaton. The shrewd observer of gaucheries, the sensitive sniffer, the erstwhile cynic, has become a mere potential papa. This spell, of course, doesn't last forever. Marriage cools the fever and lowers the threshold of disgust. The husband begins to observe what the lover was blind to, and often his discoveries affect him as unpleasantly as the treason of a trusted friend. And not only is the fever cooled: the opportunities for exact observation are enormously increased. It is a commonplace of juridical science that the great majority of divorces have their origin in the connubial chamber. Here intimacy is so extreme that it is fatal to illusion. Both parties, thrown into the closest human contact that either has suffered since their unconscious days _in utero,_ find their old capacity for disgust reviving, and then suddenly flaming. The girl who was perfect in her wedding gown becomes a ghastly caricature in her _robe de nuit;_ the man who was a Chevalier Bayard as a wooer becomes a snuffling, shambling, driveling nuisance as a husband--a fellow offensive to eyes, ears, nose, touch and immortal soul. A learned judge of my acquaintance, constantly hearing divorce actions and as constantly striving to reconcile the parties, always tries to induce plaintiff and defendant to live apart for a while, or, failing that, to occupy separate rooms, or, failing that, to at least dress in separate rooms. According to this jurist, a husband who shaves in his wife's presence is either an idiot or a scoundrel. The spectacle, he argues, is intrinsically disgusting, and to force it upon a refined woman is either to subject her to the most exquisite torture or to degrade her gradually to the insensate level of an _Abortfrau._ The day is saved, as every one knows, by the powerful effects of habit. The acquisition of habit is the process whereby disgust is overcome in daily life--the
