In a previous report Abbott and Ahmann1 showed that the hemoglobin values for rural children in several sections of Florida varied widely. These results emphasized the importance of determining the mean values for and the average limits of variation in hemoglobin in a large group of children. The present study gives data on the hemoglobin concentration of 2,205 rural white school children by sex and by age. Hemoglobin determinations were limited to children attending school; no children with pathologic conditions or gross defects were included.
SUBJECTS AND METHOD
The children were from thirty-four schools in five counties. The following tabulation shows the counties, the number of schools and of subjects from each county and the years in which the determinations were made:Hemoglobin.—Hemoglobinwas determined by a Fisher electrohemometer. This instrument is designed for determination of hemoglobin by the acid-hematin method. It employs
