Notations were made from a paper on renal tuberculosis by Braasch and Scholl to the effect that 77.4 per cent, of the total number of patients operated on at the Mayo Clinic for renal tuberculosis were dead at the end of five years. This is manifestly erroneous, in that but 119 of 847 patients operated on were reported dead, and this includes many patients who died from ten to fifteen years after operation from causes attendant to old age. In other words, the postoperative mortality at the end of five years in the hands of a skilled surgeon should not be more than 20 per cent.
