_D_e_t_a_i_l_s:

     As a part of a study of seventeenth-century English skulls three
     angles of a triangle in the cranium  

         N:  nasial angle,
         A:  alveolar angle,
         B:  basilar angle,

     were measured for 22 female and 29 male skulls. These, together
     with similar measurement of 22 female and 29 male skulls of the
     Naqada race are presented. The general objective is to investigate
     possible sex and race differences in skull shape. The angles sums
     in the  row are all equal to 180 degrees.
