GLADYS.--The chief causes of somnolence are overwork, insufficient sleep, underfeeding, overfeeding, indigestion, anæmia and other forms of physical weakness; and lastly hysteria and nervous exhaustion. From which of these are you suffering? Seven and a half hours' sleep daily is sufficient; but, if you could, we advise you to give yourself another hour. Do you eat properly? Do you eat sufficient, or do you eat inordinately? Do you have indigestion or fulness after meals? All these make you feel sleepy. Are you in any way unwell? Do you feel the cold severely, or have any symptom which would suggest that your circulation was not what it should be? Are you at all nervous, or do you belong to a nervous family? This last more commonly causes wakefulness than sleepiness. Lastly, are you worse in the morning or the evening? If you are all right in the morning, but tire and get sleepy as the day wears on, then we must look for a physical cause of your trouble. If you are worse in the morning than you are later in the day, then the cause is probably nervous. To cure yourself of your trouble you must find out and remove the cause. Take an extra hour's sleep if you can manage it. Look carefully to your digestion; many forms of dyspepsia give rise to scarcely any symptoms except sleepiness. ALICE.--Read the advice we gave to “Anxious.” You must be very careful about your digestion, and take the minimum amount of fluid that you can. Let your diet be as solid but as digestible as possible. SUFFERER.--You had far better see a physician, for you may be seriously ill, and it is quite beyond our power to help you. As regards hot-bottles, they should never be filled with boiling water, and should always be provided with jackets or wrapped in flannel. You are not the only person whose legs have been burnt through ignorance of the proper use of hot-bottles. STUDY AND STUDIO. COUNTRY LASS.--By far your best course would be to enter some small ladies' school, where you would associate with well-educated women. We do not think the scheme you mention would be very feasible. It is difficult for us to mention any one school; the fees (unless under special arrangements) would vary from £50 to £100 a year. Would you like to go on the Continent? If so, we should advise Lausanne. Perhaps you can give us a few more particulars. IRIS.--1. You might procure Creighton's _First History of France_, published at 3s. 6d., or Smith's _Student's History_, published at 7s. 6d. There is a book by Charlotte Yonge--_Aunt Charlotte's Stories from French History_--but we do not know it.--2. A thunderbolt, in the sense of a metallic substance, or bolt, hurled through the air by a thunderstorm, does not exist. The term is properly applied to the stream of electrical fluid passing from the clouds to the earth. Aërolites, or meteoric stones, have no connection with thunderstorms. Two questions are our limit.
