Note 17 — INTRODUCTION TO PART II

A simple experiment will serve to prove this shortening by the increase of, say, the lumbar curve. Take a piece of cardboard of six inches in length and place it flat on a table or against the wall. With a pencil draw lines on the table or wall as close to the upper and lower ends of the cardboard as possible. Remove the cardboard and curve it slightly across the lower portion about an inch from the end which touched the lowest line. Replace it on the lower line without interfering with the curve and you will find that it does not reach the upper line any longer. A similar condition occurring in the human being means a shortening in stature.
