A wife should not address her husband by the initial letter of his surname, as "Mr. B." or "Mr. P."; neither should a husband address his wife by the initial letter of his surname.
When intimate friends address each other by the initial letter of their names it is by way of pleasantry only, and such cases, of course, do not come within the rules of etiquette.
Peeresses frequently address their husbands, and speak of them, by the name attached to their title, in place of using their christian or family name. Thus, the "Earl of Blankshire" would be styled "Blankshire" by his wife, without the prefix of "Lord," and his usual signature would be "Blankshire," without the addition of any christian name.
Baronets' wives should not address their husbands by their surnames, but by their christian names, and should speak of them as "Sir George" or "Sir John."
The wives of knights also should not address their husbands by their surnames, but by their christian names, and should speak of them as "Sir George" or "Sir John."
The Lord Mayor should be addressed as "Lord Mayor," colloquially, and the Lady Mayoress as "Lady Mayoress," unless the Lord Mayor during office is created a baronet or receives the honour of knighthood, when he should be addressed as "Sir John" or "Sir Henry," and his wife as "Lady A."

With His Majesty this association is of frequent occurrence as regards the general public, and persons possessing special interest are constantly brought into communication with him.
