A study of the outcome of glomerular nephritis in childhood, similar to that reported from the Stanford University Medical School,1 was undertaken at the University of Rochester Medical School, Rochester, N. Y. The earlier survey was based on 186 children seen in the children's service of the Stanford University Medical School from 1920 to 1936 and demonstrated a much higher percentage of cases of chronic and fatal glomerular nephritis than had previously been found by other observers. A similar study, done subsequently in Milwaukee,2 demonstrated for the younger age groups a prognosis as serious as that found in the Stanford series.
Several reasons have been advanced for these discrepancies in statistics, the chief one being lack of agreement in classification of the condition, failure of recognition of the latent stage of glomerular nephritis, failure to make quantitative urinalyses of concentrated urine and selection in sampling of the Stanford
