Your statement that you are an American citizen, and a reference to the American Consul will procure you an interview. Punctuality to the hour appointed for the interview is essential, and ladies present themselves in full dress; gentlemen in a dress suit of black, white vest, gloves and neck-tie.
The ceremony of presentation will be explained before you are presented.
In the English court, the ladies must be presented by a lady; gentlemen by a gentleman. Strangers must have credentials from the Consul before they can be introduced.
If at a dinner, a ball, or upon any occasion you are introduced, at a friend's house, to one with whom you are not on good terms, though it be your bitterest enemy, etiquette requires you to salute him or her courteously, and make no sign of resentment whilst under your friend's roof.
If you are introduced as a petitioner to any one in authority, that introduction does not authorize you in claiming an acquaintance afterwards.
Never introduce persons who may be related to you, without calling their full name. It is done very often, even amongst well-bred people, from thoughtfulness, as, "Mrs. James, allow me to introduce my cousin Frank; Frank, Mrs. James," and poor Mrs. James is left entirely ignorant of cousin Frank's name. The proper way is to name the relationship and also the surname of the relative. If you introduce a brother or sister even, marriage may have changed the name of one. You should say: "Mrs. James, allow me to introduce to you my sister, Miss Curtis; Miss Curtis, Mrs. James."
If you are introduced to the relative of a friend, etiquette requires you to consider that relative an acquaintance, unless there is some special reason to the contrary.
It is best to avoid introductions in a public conveyance, as few people like to have their names called out in such places. If such introductions are made, however, it should be done as quietly as possible.
To introduce to a friend a person who is in any way objectionable, is an insult which fully justifies a withdrawal of friendship.
A gentleman should always raise his hat, if introduced in the street, to either lady or gentleman.
