The features in the following cut are familiar to teachers the world over. Parents may reconcile themselves to such lips, eyes, and mouths, but seldom do even neglectful parents fail to notice "mouth breathing." Children afflicted by such features suffer torment from playfellows whose scornful epithets are echoed by the looking-glass. No fashion plate ever portrays such faces. No athlete, thinker, or hero looks out from printed page with such clouded, listless eyes. The more wonder, therefore, that the meaning of these outward signs has not been appreciated and their causes removed; conclusive reason, also, for not being misled by recent talk of mouth breathing, adenoids, and enlarged tonsils, into the belief that the race is physically deteriorating. Three generations ago Charles Dickens in his _Uncommercial Traveller_ pointed out a relation between open mouths and backwardness and delinquency that would have saved millions of dollars and millions of life failures had the civilized world listened. He was speaking of delinquent girls from seventeen to twenty years old in Wapping Workhouse: "I have never yet ascertained why a refractory habit should affect the tonsils and the uvula; but I have always observed that refractories of both sexes and every grade, between a Ragged School and the Old Bailey, have one voice, in which the tonsils and uvula gain a diseased ascendency." To-day we are just beginning to see over again the connection between inability to breathe through the nose and inability to see clearly right from wrong and inability to want to do what teachers and parents wish. Physical examinations show now, and might just as well have shown fifty years ago, that the great majority of truants and juvenile offenders have adenoids and enlarged tonsils. A recent examination made by the New York board of health on 150 children in one school made up from the truant school, the juvenile court, and Randall's Island, showed that only three were without some physical defect and that 137 had adenoids and large tonsils. Dickens wrote his observations in 1860; in 1854 the New York Juvenile Asylum was started, and up to 1908 cared for 40,000 children; in 1860 William Meyer pointed out, so that no one need misunderstand, the harmful effects of adenoids. What would have been the story of juvenile waywardness, of sickness, of educational advancement, had examinations for defective breathing been started in 1853 or 1860 instead of 1905; if one per cent of the attention that has been given to teaching mouth breathers the ten commandments had been spent on removing the nasal obstructions to intelligence?
