LETTER FROM "J.B."

WASHINGTON, D.C., July 12, 1857.

DEAR SIR:--Some of our citizens, I am told, lately left here for

Philadelphia, three of whom were arrested and brought back.

I beg you will inform me whether two others--(I., whose wife is

in Philadelphia, was one of them), ever reached your city.

To-morrow morning Mrs. Weems, _with her baby_, will start for

Philadelphia and see you probably over night.

Yours Truly,
