摘要：
By the cranial coordinatograph the Cartesian coordinates of any point on the skull are obtained. Since skulls are somewhat asymmetrical the median sagittal plane as customarily determined from 3 points is unsatisfactory. The plane of minimum square deviation from 13 mid-sagittal points is therefore proposed as a more satisfactory sagittal standard plane. The 3 standard planes are mutually perpendicular. The horizontal plane makes a minimum angle with the Frankfurt horizontal plane, while the point of intersection of the 3 planes is that at which the sagittal plane meets the auricular axis. Formulae for the equations of these 3 standard planes are derived.
