Iron content was determined in fifty intact placentas plus cords, but one value, 6 standard deviations from the mean total iron content was omitted from subsequent calculations. Total iron content ranged from 34.5 to 170 mg. and averaged 75.5 mg., while the mean concentration of the mineral was 13.6 mg. and the range 7.1 to 34.8 mg. per 100 gm. of the wet weight of the samples. This loss of iron represented an average of 8.4 per cent, from a 3.5 to 18 percentage range, of a 900 mg. total dietary increment suggested for pregnant women.
