If there be a question made as to the character of the note, require the second presenting it to you, who considers it respectful, to endorse upon it these words: "I consider the note of my friend respectful, and would not have been the bearer of it, if I believed otherwise." 4.

If the party called on, refuses to receive the note you bear, you are entitled to demand a reason for such refusal.

If he refuses to give you any reason, and persists in such refusal, he treats, not only your friend, but yourself, with indignity, and you must then make yourself the actor, by sending a respectful note, requiring a proper explanation of the course he has pursued towards you and your friend; and if he still adheres to his determination, you are to challenge or post him.
5.

If the person to whom you deliver the note of your friend, declines meeting him on the ground of inequality, you are bound to tender yourself in his stead, by a note directed to him from yourself; and if he refuses to meet you, you are to post him.
6.

In all cases of the substitution of the second for the principal, the seconds should interpose and adjust the matter, if the party substituting avows he does not make the quarrel of his principal his own.
