CHAPTER III
THE THORAX
We have already had occasion to point out, in connection with the types of stature, the importance of the thorax.
The relation of the thoracic perimeter (circumference of the chest) to the total stature (see chapter on Technique) was called by Goldstein the index of life, in order to indicate that the organic resistance of any individual depends upon the proportional relation between the thorax and the whole body; whoever has a narrow chest is liable to pulmonary tuberculosis, and in his physiological entirety is a weakling (see chapter on Macroscelous and Brachyscelous Types).
