Girls in Staffordsliire are taller at ages 6, 9, and 13 than girls in Glasgow, but 
they are lighter at ages 6 and 9. We might argue from this a lack of physique in 
tStaflordshire girls who are absolutely '7 lbs. lighter at age 6 than Glasgow children, 
and relatively to their height even more than this amount. At age 9 the absolute 
difference is less and at age 1.3 Staffordshire girls are heavier than Glasgow girls 
but they are 1^ inches taller, and since the regression of weight on height at 
age 13 for girls is 3'272 lbs. we should expect Staffordshire girls to be 4'9 lbs. 
heavier than Glasgow girls, but they are not so much. I should hesitate to say 
that the physique of Staffordshire giils is inferior to that of Glasgow girls ; the 
difference probably is one of race, but such questions must remain unsolved till we 
have a far wider range of anthropometric data than is available at present for all 
the districts of Great Britain. Boys show the same characteristics to a lesser 
extent; Staffordshire boys are taller at ages 6, 9, and 13, but they are lighter in 
weight ; at age 6 they are '8 lbs. lighter than Glasgow boys ; at age 9 they are "7 lbs. 
lighter and at age 13 they are 1*7 lbs. heavier. Again relative to their height 
Staffordshire boys are lighter than Glasgow boys at the three ages for which a 
comparison can be made. 
Comparing boys and girls in Staffordshire we find that girls of 6 and 9 are 
shorter and ligliter than bo3's of the same age, but at 13 and 13^ girls are both 
taller and heavier. At 6 and 9 years the regression of weight on height is 
practically the same for both sexes, but at 13 and 13| the regression of weight on 
height is greater for girls than for boys ; girls are heavier proportionally to their 
height than boys are. For giils of 13 an additional inch in height should mean 
3 3 lbs. more weight while for boys the additional pounds expected are only 2"8, 
while for girls of loh we expect 3'4 lbs. increase for every inch of growth and for 
boys 3"2 lbs. increase. A comparison of the regression coefficients with those given 
for Glasgow in Table I will show that the coefficient is higher in Staffordshire for 
children of 6 and boys of 9 than in any of the school groups in Glasgow. The 
regression coefficient found for girls of 9 and 13 in Staffordshire is practically 
identical with that found in Group D in Glasgow, and boys of 13 in Staffordshire 
would seem to be most like boys of Group C in Glasgow.
