Persons liable to fainting fits should be careful to avoid extremes of temperature, such as very hot or very cold baths. Fall, A.--After a fall from a height, where there is no apparent outward injury, there is often such a severe shock to the spinal cord and brain that continued unconsciousness occurs. In such a case, foment the spine at first, to remove the effects of the concussion. This may bring on serious difficulty of breathing, owing to congestion of the spinal cord. This can be removed by applying cold cloths along the spine. If the difficulty of breathing be present from the first, then apply the cold at once. The first effect of such a fall is to deprive the brain and spinal cord of vital force. This must be restored by _heat_. Subsequent effects due to congestion can be removed by cold. The effects of a shock in a railway accident may be similarly treated. Common sense will guide in using heat or cold by watching the effect. Where heat fails try cold. This is the simple rule. It is good also to give the patient some simple purgative medicine, and some warm drink. _Avoid all doses of alcoholic drinks._ We have known the flickering flame of life almost extinguished by a teaspoonful of brandy. Feeding, Over.--It is well to remember that over-feeding is a relative term. To take more than a weak stomach can digest, is to over-feed, although very little be taken. We give some invalids food every two hours but that food is only two-thirds of a teacupful of milk, mixed with a third of boiling water. In every case we must watch to give the right amount, no less and no more. Every case will require to be considered by itself in the light of common sense. The amount of food eaten should be just sufficient to supply the body with material to replace that consumed in work, build up its wasted tissues and leave a slight surplus over for reserve store. Anything more is harmful. In youth, if too much be eaten, nature relieves herself by giving the transgressor of her laws a bilious attack, during which there is no appetite, and so the excess is worked off. In later years this safety valve does not work, and the surplus is generally stored as useless fat, impeding the action of the heart or other internal organs, or as gouty deposits in various parts. The Anglo-Saxon race at all events does not limit its diet as we think it should, and Sir Henry Thompson, M.D., has stated that in his opinion more ill-health arises from over-eating than from the use of intoxicating liquor, great a source of illness as this last undoubtedly is. Temperance in diet is absolutely necessary therefore, if one would be healthy, and the avoidance of stimulating foods, with a restriction of flesh foods especially, is a precept which the great majority of well-to-do people need to attend to.
