increase of stature made by girls after that year is almost 
entirely in the trunk. The following are the lengths of the

Petvic MEASUREMENTS. 
A description of the pelvic measurements has already 
been given. The following table gives the actual meas- 
urements of boys. The figures present much the same 
features of growth as those of other parts of the body. 
From 54 to 8 years the growth is somewhat slow, and at 8 
years there is a marked retardation in all the measure- 
ments; from the 8th year to the 10th year there is a rapid 
increase in the rate of growth. After the tenth year, the 
measurements do not increase so rapidly as in the years 
immediately preceding, but the growth is regular until the 
adult size is attained.
