The dull colored girls have a stronger hand grasp than the bright. Comparing the colored girls with the white girls, they are less sensitive to locality than the white girls, but much more sensitive to heat. Comparing the colored boys and girls, the boys are more sensitive both to locality and heat. Colored boys are remarkably sensitive to heat on the left wrist. COLOKED CHILDREN BEFORE AHD AFTER PUBERTY. ' While the number of colored children measured is comparatively small, yet it may be interesting to note some diflferences indicated in Table I: Among the boys and girls the per cent of long heads is much greater after puberty than before. This is also true of the white boys, but not of the white girls. The colored boys are more sensitive to heat and locality after puberty than before. The reverse is true with the white boys, but the colored girls, like the white girls, are less sensitive after puberty. Table I.—Colored children before and after puberty.
