As explained in the foregoing chapter, the correct formal greeting is:
"How do you do?" If Mrs. Younger is presented to Mrs. Worldly, Mrs.
Worldly says "How do you do?" If the Ambassador of France is presented to
her, she says "How do you do?" Mrs. Younger and the Ambassador likewise
say "How do you do?" or merely bow.

There are a few expressions possible under other circumstances and upon
other occasions. If you have, through friends in common, long heard of a
certain lady, or gentleman, and you know that she, or he, also has heard
much of you, you may say when you are introduced to her: "I am very glad
to meet you," or "I am delighted to meet you at last!" Do not use the
expression "pleased to meet you" then or on any occasion. And you must not
say you are delighted unless you have reason to be sure that she also is
delighted to meet you.

To one who has volunteered to help you in charitable work for instance,
you would say: "It is very good of you to help us," or, "to join us."

In business a gentleman says: "Very glad to meet you," or "Delighted to
meet you." Or, if in his own office: "Very glad to see you!"

Informal greetings are almost as limited as formal, but not quite; for
besides saying "How do you do?" you can say "Good morning" and on
occasions "How are you?" or "Good evening."

On very informal occasions, it is the present fashion to greet an intimate
friend with "Hello!" This seemingly vulgar salutation is made acceptable
