A bulb enema syringe may be used instead of the fountain, and less water--a pint or even less, and the water tepid or cold, may be preferred by some. The disadvantage of a bulb syringe is however that sometimes air gets in along with the water, causing pain and discomfort. Consumption, Prevention of.--This most insidious and deadly disease is caused by a tiny vegetable growth derived from persons or animals already suffering from tuberculosis. The spit of consumptive patients swarms with such germs, and when it dries and becomes dust the germs may be stirred up and breathed, or may mix with food, _e.g._, milk, and so enter the body. A dried handkerchief may also carry the infection. But these germs, though continually carried into the lungs of almost all, do not develop in all. The healthy body can resist them, and it is only in the body which possesses little resistance, owing to a low state of health, that they take root, and so start the disease. Want of pure air, such as is caused by badly ventilated rooms, dark, damp, and dirty houses, want of good food, or bad food, alcoholic drinks, frequent illnesses, dirty habits, are powerful causes in producing this low state of health, which is so favourable to the growth of the consumptive germ. Therefore we insist on fresh air, especially for children in schools, for employees in factories, for clerks in offices. All places of public resort should be provided with proper ventilation. The breath from the lungs is loaded with poisonous organic matter, and if continually re-breathed poisons the blood. The smell of a room is often an indication of whether the air is pure or not, especially in the nostrils of one entering from the outer air. Let all windows be kept open day and night, and let fresh air and sunlight continually flood the room. Nothing will kill disease germs quicker. Avoid choosing a residence with but little open spaces around, such as basement tenements and back to back houses. Have an open fireplace in the room. Gas or oil for lighting, heating, or cooking renders the air impure, and in need of constant renewal. _See_ Air. Dirt, either in the house or around, poisons the air, and refuse should be removed to a distance from the dwelling. Tea leaves should be sprinkled on floors before being swept. Remove dust with damp dusters, which should be boiled. Cleanliness should be strictly attended to, and schools and factories should be plentifully supplied with soap and water. The food consumed by the vast majority of people is far from being as nourishing as it should be. Tea and white bread have replaced porridge and milk. This should not be. Cocoa might with advantage replace tea, and porridge and milk by itself would make a highly nutritious meal (_see_ articles on Diet). Stimulants are not required by the healthy body, and intemperance is a fruitful predisposing cause of consumption. Skim milk is not a suitable food for the young. _See_ Infants' Food.
