Such slight irregularities need not give rise to anxiety; but if there is an unwonted delay, combined with other symptoms of ill-health, as headache, pain in the side and back, a sense of languor and exhaustion, loss of appetite, and nausea, and fitful sleep, then it is important that some steps be taken to bring on the courses. For this purpose, soaking the feet in hot-mustard water, a tumbler of hot ginger or camomile-tea, a brisk walk, or a gentle laxative will generally be found sufficient. Gently kneading the lower abdomen and loins is a familiar, and if intelligently done, a safe means for the same purpose. More violent means than these should be eschewed. Whichever are used subsequent to their employment, rest, in a recumbent position, in a warm room should be secured. WHEN THE CHANGES ARE PAINFUL. There are wide individual differences in this respect. Some young women suffer much from local pains, headache and languor at such epochs, without apparently losing anything in general health; others experience no distress whatever. The causes of painful periods are various. Sometimes they depend on a tendency to rheumatism or to ague. Over-work, or excessive devotion to social duties and pleasures, is often their source. Cold and damp are common incidental causes. Green sickness and general debility are sometimes to blame. Of course the treatment must depend on which one of these is present. It is a good rule, however, always to wear flannel next the skin; also, to avoid exposure to the weather for several days before the change is expected. A large, hot, linseed-meal poultice, over which a dessert-spoonful of laudanum has been sprinkled, or a large mustard-plaster, spread on the lower abdomen, will afford much relief. A hot brick or bottle of hot water wrapped in flannel, and applied to the small of the back, is often of great service. Rest in bed is always to be recommended. A tea-spoonful of sweet spirits of nitre will sometimes bring early relief. But if these simple means are not sufficient, it would be better to consult a physician. A common belief is that such troubles are cured by marriage. Sometimes they are, but we do not approve the remedy. The state of marriage should be entered upon in perfect health and full vigor. Upon it depends the health of future generations, and it were better for them did only those assume its bonds who are able to endow their children with sound physical frames. THE AGE OF NUBILITY. It does not follow, because a girl is capable of marriage, that she is fit for it. Science teaches us many valid objections to too early unions. It goes farther, and fixes a certain age at which it is wisest for woman to marry. This age is between twenty and twenty-five years.
