C.  RESULTS  OF  THE  STANDARD  ARMY  PHYSICAL  MEASUREMENTS.
                                    I. AGE  OF RECRUITS.

   Table 2, préparée! from material  published in Gould 2  and from material fur-
nished by  the  War Risk Bureau, gives  the  relative frequency  of  the  various
âges of officers and men serving in the Civil and World Wars.   It  is  apparent
that the great  majority  of the men measured  for  the data in this book were
between the âges of 18 and 31, inclusive.    (See Plate IV.)
