Third subject, in plate 7, shows a corset similar in construction to those shown in plates 5 and 6. Greatest pressure is directly around the lower part of thorax with the same physiological effect. Full breathing is impossible in such corsets, as can easily be determined by taking the measure of the chest in expiration and inspiration, with and without the corset. Plate 8 shows the same subject with the correct corset on, the line of pressure being from lower part of abdomen to center of back by way of the hip bones. The contrast between this last and the three preceding illustrations should be illuminating to the careful observer. |
