In yesterday's editions, a map showing proposed new City Council districts for Baltimore incorrectly illustrated a boundary line between the proposed 4th and 6th Districts. The correct boundary is Charles Street. A map of the districts appears on Page 2B.

An article about biological security in Sunday's editions of The Sun gave an incorrect last name for Joseph Fitzgerald, a senior associate of the Johns Hopkins Center for Civilian Biodefense Strategies.

The Sun regrets the errors.
