Ladies’ Book of Etiquette, and Manual of Politeness [EPUB ebook] 

Excerpt: "In preparing a book of etiquette for ladies, I would lay down as the first rule, "Do unto others as you would others should do to you." You can never be rude if you bear the rule always in mind, for what lady likes to be treated rudely? True Christian politeness will always be the result of an unselfish regard for the feelings of others, and though you may err in the ceremonious points of etiquette, you will never be impolite."
