HEMOGLOBIN IN NORMAL MALES AND FEMALES DURING DIFFERENT AGE PERIODS 



both sexes (from 16 to 70 years) the hemoglobin maintains a fairly con- 

 stant level of about 16 per cent. From the third month to the fifteenth 

 year the values obtained in the female appear to slightly exceed the male,

 female averaging close to 15.5 per cent, while in the male it reaches nearly 

 17 per cent. 



A few observations taken from Meyer and Butterfield are given in the 

 table below. They employed the same method as did Williamson and
