OFFICER’S PRISON. - Yesterday afternoon the commissioned Yankee officers confined in the Libby prison Twentieth and Cary streets, were removed therefrom to the new quarters expressly prepared for them, on Eighteenth street, near Main. The prisoners formed quite a respectable and select company, and numbered one hundred and twenty five in all, including majors, colonels, captains and lieutenants. At five o’clock, A. M., the whole number of prisoners received fell a trifle short of five thousand.
