Values given for adult female are not necessarily those of the mother. Values in parentheses are ranges and con- 

 form, unless otherwise specified, to estimate "c" of the 95% range (cf Introduction).

84. ERYTHROCYTE AND HEMOGLOBIN VALUES FROM BIRTH TO MATURITY: MAN 



Values are smoothed means from plotted curves. Values in parentheses are ranges and conform, 

 specified, to estimate "c" of the 9 5% range (cf Introduction).

III Cord clamped after placental separation, averages 560,000 more RBC/cu mm and 2.bg/100 ml more hemoglo- 

 bin during first week of life than cord clamped immediately after birth. In newborn, heel blood (capillary) higher 

 in RBC and hemoglobin than blood from superior sagittal sinus.
