Commanding Depot Prisoners of War, Elmira, N. Y.: COLONEL: I am directed by the Commissary-General of Prisoners to acknowledge the receipt of your inspection report for the week ending December 25, 1864, and to inform you that if cases of smallpox continue to multiply you are authorized, after consultation with the proper medical authorities, to pnt up temporary buildings for the isolation of that class of patients. Place it within the inclosure, if practicable, but if circumstances require it to be established outside it should be suitably guarded.
