The weight of girls averages, at 5} years, about 6 pounds 
less than that of boys, and up to age 104 years the average 
is about 4 pounds less. After that year the girls increase 
more rapidly than the boys, and at 124 years the weights 
are equal. From 124 years to 14} years the girls are 
slightly heavier than the boys, but at 15 years they are 
again equal; after 15 years the weight of the boys increases 
very considerably until adult age is reached, while that of 
the girls does not increase beyond the 17th year.
