In any disease in which the mortality rate is unusually high, numerous and not altogether successful methods of treatment are likely to be advocated. This has been true of erysipelas in infants. Morse1 reported 90 per cent mortality in infants; Erdman2 reported 39.7 per cent; while Schaffer and Rothman3 gave the following results: infants under 1 month of age, 80 per cent; under 6 months, 53 per cent; from 6 to 12 months, 47 per cent, and from 1 to 2 years, 14 per cent. As regards the influence of different forms of therapy, Knox4 reported a mortality rate of 60 per cent in infants under 6 months of age treated by local measures; Robertson5 quoted 65 per cent in infants under 12 months of age treated by exsanguination-transfusion; Borovsky,6 29 per cent by the use of a 2 per cent solution of mercurochrome-220
