The second subject, plate 7, shows front view of same corset as plate 5, and the pronounced curve around base of thorax in line indicated by arrows. Pressure is greatest at this point and across diaphragm. Contrast the corset in plate 7 with that of the correct corset in plate 8, with normal width at base of thorax and curve at waist on sides where curve is physiologically correct, and does not interfere with expansion of rib wall or movement of diaphragm in breathing. |
