Pale Faces & Black Mouths
Native Americans commonly called white settlers “pale faces.”
They also called them “black mouths.”
Mouth breathing (as opposed to nasal breathing) is responsible for numerous diseases, not just dental and facial ones.
George Catlin (Shut Your Mouth and Save Your Life, Ninth Edition, 1891) wrote …
“There is no animal in nature, excepting Man, that sleeps with the mouth open; and with mankind, I believe the habit, which is not natural, is generally confined to civilized communities, where he is nurtured and raised amidst enervating luxuries and unnatural warmth, where the habit is easily contracted, but carried and practised with great danger to life in different latitudes and different climates; and in sudden changes of temperature, even in his own house.
“The physical conformation of man alone affords sufficient proof that this is a habit against instinct, and that he was made, like the other animals, to sleep with his mouth shut — supplying the lungs with vital air through the nostrils, the natural channels; and a strong corroboration of this fact is to be met with amongst the North American Indians, who strictly adhere to Nature’s law in this respect, and show the beneficial results in their fine and manly forms, and exemption from mental and physical diseases, as has been stated.
“The Savage infant, like the offspring of the brute, breathing the natural and wholesome air, generally from instinct, closes its mouth during sleep; and in all cases of exception the mother rigidly (and cruelly, if necessary) enforces Nature’s Law in the manner explained, until the habit is fixed for life, of the importance of which she seems to be perfectly well aware. But when we turn to civilized life, with all its comforts, its luxuries, its science, and its medical skill, our pity is enlisted for the tender germs of humanity, brought forth and caressed in smothered atmospheres which they can only breathe with their mouths wide open, and nurtured with too much thoughtlessness to prevent their contracting a habit which is to shorten their days with the croup in infancy, or to turn their brains to Idiocy or Lunacy, and their spines to curvatures — or in manhood, their sleep to fatigue and the nightmare, and their lungs and their lives to premature decay.”

“The Registrar-General shows an average of over 700,000 infants born in England per annum, and over 100,000, which die under one year of age – 12,738 of these from Bronchitis, 3660 from the pains of teething, and 19,000 of convulsions, and says, ‘suffocation in bed, by overlaying or shutting off the air from the child, is the most frequent cause of violent deaths of children in England.'”
