Those FersoDS engaged in occupations requiring the hands alone to move, while the lower limbs remain motionless, should bear in mind that without constantly raising the frame to an erect position, and giving a slight exercise to all parts of the body, such a practice will tend to destroy their health. They should, moreover, sit in as erect a position as possible. With seamstresses there is always more or less stooping of the head and shoulders, tending to retard circulation, respiration, and digestion, and produce curvature of the spine. The head should be thrown back, to give the lungs full play. The frequent long-drawn breath of the seamstress evinces the cramping and confinement of the lungs. Health cannot be expected without free respiration. The life-giving element is in the atmosphere, and without it in proportionate abundance must disease intervene. Strength ttnd robustness must come from exercise, Confined attitudes are in violation of correct theories of healthy physical development and the instincts of nature. Those accusfomed to sit writing for hours, day after day, can form some idea of the exhausting nature of the toil. some and ill-paid labor of the poor seamstress.
