The study of disabilities among employees of specific industries is contributing information which should be helpful not only to the industrial physician but also to the general problem of disease control and to the formulation of specific preventive and ameliorative measures. Gafafer and Frasier1 studied disability among employees of the Boston Edison Company as represented by absences due to disabilities lasting one calendar day or longer during 1933 to 1937 inclusive. The causes of disability are broadly grouped into industrial accidents, nonindustrial accidents, respiratory diseases and nonrespiratory diseases. There were altogether 16,241 total years of exposure with 17,628 absences lasting one calendar day or longer over the five year period. These absences totaled 133,022 days of disability. The frequency of absences by years showed a practically stationary trend for both males and females, the trend for the former being on a lower level.
