Our yellow fever reports show that the dread disease is still making headway in the scourged cities.  For the week ending Saturday the record stands as follows: New Orleans, 2,877 cases, 867 deaths; Vicksburg, about 800 cases, 185 deaths; Memphis, 721 cases and 241 deaths.  For the twenty four hours ending Saturday, there were reported in Memphis 148 new cases and 77 deaths.  Earnest appeals are being made for aid, and contributions for the sufferers are still being forwarded.  In Memphis volunteer physicians and nurses are arriving, and in both that city and Vicksburg several prominent citizens are reported among the sick and dead.  Herbert S. Landrum, city editor of the Memphis Avalanche, is reported down with the disease.
