Formula.  A woman should introduce her husband
       to acquaintances as “My husband,”
       and not “Mr.”; to intimate friends as
       “Henry.”

  Hostess.  Introductions to the hostess at an
       “At Home,” or reception by women assisting
       hostess, of those who have been invited to
       the entertainment by them, are not recognized
       thereafter unless by mutual consent.

       The hostess receiving in her own home
       should offer her hand to all to whom she is
       introduced.

       The hostess introduces her immediate family
       to all her guests.  No formal permission
       is necessary.

       In the case of one woman desiring an introduction
       to another, the hostess should be
       asked to bring this about.

Introduction, letters of.  The introduction of one
       person to another by letter is as follows:  The
       party introducing writes the name of the party
       he introduces upon his own card, and above
       his name the words:  Introducing Mr. Wilson
       (his friend’s name).  It is then placed in an
       envelope and addressed to the person to whom
       the introduction is to be made.  On the
       lower left-hand corner of the envelope, Introducing
       Mr. Wilson, is written, and given to
       the bearer unsealed.

The party to whom a letter of introduction is given should send it by mail to the party they desire to be introduced to, enclosing their own card with address, and then await invitation to call.

       This is preferable to calling in person, as
       it may not be agreeable or desirable for the
       party to open and begin such an acquaintance.

       In business introduction, such formality
       may be set aside.

       If a letter of introduction is personally delivered,
       the party presenting it should also
       enclose card.

       If the party called upon is not at home,
       the letter or card should not be left, but sent
       by mail or messenger.

The one giving another a letter of introduction
may write to the friend explaining
why it is done, who and what the party is.

If a man sends a letter of introduction to
a woman, she should acknowledge it, and, if
she wishes, invite him to call.

Party receiving—­women.  The party receiving
cards of introduction should call in person
upon woman introduced; if unable to do
so, a letter should be sent, stating reasons of
inability to be present.  A member of the
family may make the call instead.  It should
be done within three days.

If not agreeable to receive party for any
reason, a card may be sent or left.  No personal
visit need be made.
