that a method of classification which divides the data into groups varying from 
1*6 per cent, to 32 2 per cent, of the total is not entirely satisfactory.

But apart from this it is interesting to compare the percentage of the various 
hair colour groups so obtained in Birmingham with those obtained elsewhere. 
Table II is copied from Tocher's "Pigmentation Survey of School Children in 
Scotland*." The comparison between the hair colour schemes cannot be made in 
detail because the classification is not identical. The percentage of red haired

children is less in Birmingham, where it does not exceed 3'5 per cent., while in 
Scotland it is not less than 5 per cent.; the black haired class, however, would 
seem to be present in Birmingham in larger numbers. The two classes denomi-

go in the Birmingham arrangement under the head of Light Brown.
