d,
to be sealed before delivery by the one introduced. They should receive
immediate attention by the parties who receive them. When a gentleman
delivers such a letter to a lady, he is at liberty to call upon her,
sending her his card to ascertain whether she will receive him then, or
appoint another hour that will be more convenient. The same rule is to
be observed by those whose stay in the city is short. He may also send
it to her with his card bearing his address.

A letter of introduction should not be given, unless the person writing
it is very well acquainted with the one whom he introduces, and the one
to whom he writes. If the person who receives such a letter is really
well-bred, you will hear from him or her within twenty-four hours, for a
letter of introduction is said to be like a draft, it must be cashed at
sight. The one receiving it either invites you to dine, or to meet
others, or to a drive, or to visit some place of amusement. Too great
caution cannot be exercised in giving a letter which makes such demands
upon an acquaintance.

When the letter of introduction is left with a card, if there is a
gentleman in the family, he may call upon the stranger the next day,
unless some engagement prevents, when he should send his card with an
invitation. If the letter introduces a gentleman to a lady, she may
write a note of invitation in answer, appointing a time for him to call.

The following is an appropriate form for a letter of introduction.

months in your city. I am sure that an acquaintance
with her will be a pleasure to you, as it will also
be to Miss Thornton. Any favor you may show her
during her stay in your city, I will consider a
personal favor._
