A Good Disinfectant. – The Assistant Provost Marshall in charge of the Military Prison of the Eastern District, has adopted the practice of spreading loam and lime on the floors of the prison, which proved such an excellent absorbent of noxious gasses, that since its introduction, no case of small-pox has been reported. Before it was sprinkled on the floor, one or more cases used to be reported daily. The remedy is worth a trial.
