"Etiquette, the observance of formal rules of conduct, is nowhere more admirely proper than in connection with the funeral."

"One of the underlying purposes of all good manners is to lend grace and dignity to life to ameliorate its crudities, to do away with its vulgarities, to regulate the familiar intercourse of human beings in such a way as to avoid friction, coarseness and that which leads to contempt. And good manners in connection with all that has to do with death are just as essential."
