In a previous paper1 we reported the observations on successive roentgenograms of the chests of 130 children taken during measles. It was shown that shadows suggesting pulmonic infiltration were present in 62.4 per cent of the patients less than 4 years of age and in 42.2 per cent of the patients 4 years of age or over. In the cases showing infiltration, this was present in at least 61 per cent before or during the height of the eruption. Thus the infiltration was often present in cases which were considered clinically mild. Abnormal intensity of the pulmonary markings, pleuropulmonary changes and progressive and retrogressive hilar changes were also present.
The purpose of the present study was to report the observations on roentgenographic reexamination of the chests of these children from six to ten months after measles. We realize that the one difficulty in judging the report of these observations
