Dr. Mary E. Walker. – Some excitement among the juveniles and negroes was produced Saturday morning, by the appearance on the streets of Mary E. Walker, the Yankee surgeon, in her outré costume, of men's pants, boots and short cloak and broad brimmed beaver hat. She was walking between two detectives, who conducted her to Gen. Winder's office, and thence back to the Castle. The cause of her visit to the General we did not learn.
