Some of the doctor’s arguments, however, seem erroneous. For example, he thinks the masculine fashion of cutting off the hair an evidence that men instinctively know hair to be injurious—that is to say, a disadvantage in the struggle for existence. This I can not admit; it does not follow, for testators have a fashion of cutting off legatees-expectant, yet legatees-expectant are not injurious—until known to be cut off; and then the testator’s struggle for existence is commonly finished. Capitalists have a fashion of cutting off coupons; it hardly needs to be pointed out that coupons are not amongst the malign influences tending to the shortening of life. I have tried (with some success, I hope) to show that hair is a disadvantage, but this view derives no support from the scissors. If the hair of men were obviously, conspicuously beneficial; if it made them healthy, wealthy and as wise as they care to be; if they needed it in their business; if they could not at all get on without it—they would doubtless cut it a little oftener and a little closer than they do now. Men are that way. The truth of the matter is plain enough. Men become bald because they keep cutting their hair. Every man has a certain amount of capillary energy, so to say. He can produce such a length of hair and no more, as the spider can spin only so much web and then must cease to be a spinster. By cutting the hair we keep it exhausting its allowance of energy by growth; when all is gone growth stops, and the roots, having no longer a use, decay. By letting their hair grow as long as it will women retain it. The difference is the same as that between two coils of rope, equal in length, one of which is constantly payed out, the other not. If this explanation do not compose the immemorial controversy about the cause of men’s baldness the prospect of its composure by that phenomenon’s universality will be hailed with delight by all who love a quiet life. The first generation to forget that men ever had hair will be the first to know the happiness of peace; the succeeding one will begin a dispute about the cause of hair in woman. An important discovery made and stated with confidence is that to the human tooth, also, civilization is hateful and insupportable. Dr. Denison Pedley, whose name carries great weight (and would to whomsoever it might belong) examined the teeth of no fewer than 3,114 children, and only 707 had full sets of sound ones. That was in England; what would be shown by a look-in at the mouths of the young of a more highly civilized race—say the Missourians—one shudders to conjecture. That nearly all the savages whom one meets have good enough teeth is a matter of common observation; and missionaries in some of the remoter parts of Starkest Africa attest this fact with much feeling. Yet in all enlightened countries the prosperous dentist abounds in quantity.
