 Feet or legs, roll not the eyes, lift not one eyebrow higher than the other, rye not the mouth, and bedew no man's face with your spittle by approaching too near him when you speak. Kill no vermin as fleas, lice, ticks, etc. in the sight of others. If you see any filth or thick spittle, put your foot dexterously upon it. If it be upon the clothes of your companions, put it off privately.
