Exposure is one of the principal sources of injury to the constitution, and therefore the clothing should always be adapted to the season of the year, and the temperature of the air, whether children are at home or abroad. Girls are generally clothed sufficiently warm while at home, but when they are going from home, they change their warm apparel for thinner and cooler garments. They are often allowed to expose themselves to the chilling blasts of winter, with their arms naked, their breasts and shoulders exposed, and their feet clad with thin stockings and shoes, in the place of those just laid aside, which were warm and comfortable.--This is a practice that cannot be too much deprecated, being one of the great evils of dress and fashion, upon whose altar thousands have been sacrificed. How many do we find in these days with enlarged tonsils and broken croaking voices, the fruits of exposure and nothing else? The practice of tight lacing is another fruitful cause of destruction of health and broken-down constitutions. Young girls should not lace at all--an easy smooth jacket to make the dress fit smoothly is all they should wear. Are we asked why lacing is injurious? We answer, first, the ribs are soft and very elastic and the cartilages that join them to the breast bone are softer than the ribs. If then a jacket or corset be laced around the ribs or chest, so as to prevent a free and full play of the ribs at every inspiration, in the same proportion is the cavity of the chest diminished, and consequently the lungs are deprived of a certain amount of atmospheric air, in proportion to the contraction of the ribs, produced by the laced jacket or corset. Thus the order of nature is deranged and the system is deprived of that due proportion of oxygen which is necessary to health, the vitality of blood and the vigor and proper proportions of the system. One of the consequences of tight lacing therefore is, that the lungs are prevented from discharging a due portion of carbonic acid gas from the blood, and receiving in lieu therefor of due proportion of oxygen from the atmosphere. Hence the person looks pale, the lips assume a blue or purplish color, the breathing is labored, the breast heaves and the circulation is prevented from going on as freely as it should. The small air vessels of the lungs are partially obliterated, they become diseased in their action and tubercles form in them or the lungs; these remain to become in a few years the seeds of an incurable consumption.
