Christopher Dock, A Hundred Necessary Rules of Conduct for Children (1764)
“ Turn your face to one side, hold the hand before it, put the uncleanliness of the nose in a handkerchief and do not look at it long, let the spittal fall upon the earth and tread upon it with your foot. Do not accustom yourself to continual hawking, grubbing at the nose, violent panting, and other disagreeable and indecent ways. ”
