465. _To make Verjuice._--The acid of the juice of the crab or wilding is called by the country people, verjuice, and is much used in recent sprains, and in other cases, as an astringent or repellant. 466. _Medicines in Travelling._--In case of change of food disagreeing with the stomach, dissolve a tea-spoonful of Epsom salts in half a pint of water, as warm as it can be drunk, and repeat the dose every half-hour, until it operates. For diarrhœa, or acidity of stomach, mix one drachm of compound powder of kino, with half an ounce of compound powder of chalk; divide into six powders, and take one or two a day, in three table-spoonfuls of water, and a tea-spoonful of brandy. 467. _To prevent Sea-sickness._--Pass a broad belt round the body, and place within it, on the region of the stomach, a pad stuffed with wool or horse-hair; this, when tightly braced, restrains the involuntary motion of the stomach, occasioned by the lurching of the vessel. During sickness, very weak cold brandy and water will be found the best means of allaying the heat and irritation. The frequent use of any sea-sickness preventive is, however, attended with danger. 468. _Valuable properties of Cherry-tree Gum._--The gum that exudes from the trunk and branches of the cherry-tree is equal to gum-Arabic. Hasselquist relates that, during a siege, more than an hundred men were kept alive for two months nearly, without any other sustenance than a little of this gum taken into the mouth sometimes, and suffered gradually to dissolve. 469. _How to get Sleep._--How to get sleep is to many persons a matter of high importance. Nervous persons who are troubled with wakefulness and excitability, usually have a strong tendency of blood on the brain, with cold extremities. The pressure of the blood on the brain keeps it in a stimulated or wakeful state, and the pulsations in the head are often painful. Let such rise and chafe the body and extremities with a brush or towel, or rub smartly with the hands to promote circulation and withdraw the excessive amount of blood from the brain, and you will sleep in a few moments. A cold bath, or a sponge bath and rubbing, or a good run, or a rapid walk in the open air, or going up or down stairs a few times, just before retiring, will aid in equalizing circulation, and promoting sleep. These rules are simple and easy of application in castle or cabin, and minister to the comfort of thousands who would freely expend money for an anodyne to promote "Nature's sweet restorer, balmy sleep."
