5. His Excellency applies to the President of the United States, an Ambassador of the United States, or the Governor of a State. This title should be written on a line by itself; as,—
His Excellency,
Gov. C. M. Croswell,
Adrian,
Mich.
6. In addressing a married lady, the professional title of her husband is sometimes used; as, Mrs. Dr. Haven.
7. Two professional titles meaning the same thing should never be used; as, Dr. A. D. Smith, M. D.
Large Cities.—When the person to whom the letter is addressed, lives in a large city where letters are delivered at places of business or private residences, the title and name, number of house and street, the city, and state should be given; as,—
A. S. Barnes & Co.,
34 and 36 Madison St.,
Chicago.
Ill.
REMARKS.
1. The title and name should be written first, the number and street to the right and a little below, the city below the name of the street, and the state under the city.
2. The name of the state might be omitted in the address above given. It is not really necessary to give the state, when the city is so widely known that no mistake can arise, if the name of the state is omitted; as, New York, Philadelphia, Boston.
