Great care should be taken to separate the healthy from the infected. The nurses selected for attending scarlet fever patients should be those who have previously had scarlet fever themselves. Dirty linen should be removed at once, and be put into boiling water. Very little furniture should be in the room of a scarlet fever patient--the less the better--it only obstructs the circulation of the air, and harbours the scarlet fever poison. The most scrupulous attention to cleanliness should, in these cases, be observed. A patient who has recovered from scarlet fever, and before he mixes with healthy people, should, for three or four consecutive mornings, have a warm bath, and well wash himself, while in the bath, with soap; he will, by adopting this plan, get rid of the dead skin, and thus remove the infected particles of the disease. If scarlet fever should appear in a school, the school must for a time be broken up, in order that the disease might be stamped out There must be no half measures where such a fearful disease is in question. A house containing scarlet fever patients should, by parents, be avoided as the plague; it is a folly at any time to put one's head into the lion's mouth! Chloralum and carbolic acid, and chloride of lime, and Condy's fluid, are each and all good disinfectants; but not one is to be compared to perfect cleanliness and to an abundance of fresh and pure air--the last of which may truly _par excellence_ be called God's disinfectant! Either a table-spoonful of chloralum, or two tea-spoonfuls of carbolic acid, or two tea-spoonfuls of Condy's fluid, or a tea-spoonful of chloride of lime in a pint of water, are useful to sprinkle the soiled handkerchiefs as soon as they be done with, and before the be washed, to put in the _pot-de-chambre_, and to keep in saucers about the room; but, remember, as I have said before, and cannot repeat too often, there is no preventative like the air of heaven, which should be allowed to permeate and circulate freely through the apartment and through the house: air, air, air is the best disinfectant, curative, and preventative of scarlet fever in the world! I could only wish that my _Treatment of Scarlet Fever_ were, in all its integrity, more generally adopted; if it were, I am quite sure that thousands of children would annually be saved from broken health and from death. Time still further convinces me that my treatment is based on truth as I have every year additional proofs of its value and of its success; but error and prejudice are unfortunately ever at work, striving all they can to defeat truth and common sense. One of my principal remedies in the treatment of scarlet fever is an abundance of fresh air; but many people prefer their own miserable complicated inventions to God's grand and yet simple remedies--they pretend that they know better than the Mighty Framer of the universe! 228. _Will you describe the symptoms of Chicken pox_?
