What can we do? Symptoms are often bettered at an asylum. Phobias vanish and so do fears for the immediate future. All energies may be guided to one channel and the person may be made useful and his fear of being useless thus cured. The old are thus often anxious to do little services to show they are not worthless and little tasks can occupy them without strain. A patient pensioned after sixty-five years of work could get no other employment, felt useless, instead of being cheery became depressed, and was cured by being re-employed. The influence of young people keeps up interest in life--especially marriage with a young person, the development of a hobby, collecting anything, such as stamps, coins, books; witnessing new sights, but not fairs, where numbers confuse. Drugs give temporary relief. Small doses of morphine give exhilaration and arouse the imagination, but its effects soon wear off. “Phosphorus in solution is the most effective drug for prolonged use.” It is a mental and nervous stimulant and aphrodisiac, increasing mental power and producing a sense of well-being. One-fiftieth-grain doses several times a day, stopping just as soon as the intellect begins to brighten, are often beneficent. This can be kept up for years. Perhaps amorphous phosphorus may be used. * * * * * Sir Dyce Duckworth[152] asks: Why are some remarkably young for their age and others old? It cannot all be explained by anything in the individual life or habits. Perhaps it is in part because the ancestors lived a hard life. We want the degree of inherent vitality proper to each individual patient. This would be as important for prognosis in pneumonia as are the hæmic leucocytes. Arterial hardening may be local only, for example, radial. There are two kinds of arterial degeneration, namely, the brittle and the tough, the former more liable to cause hemorrhages and fatty degeneration. Very important is the discovery that the rigidity of calcified arteries is greatly increased immediately after death. The lime is present before, as disclosed by the X-rays, but it is like wet or unset mortar and only sets after death under the influence of carbon dioxide and the rapidly diminishing alkalinity of the blood. The so-called air in the arteries after death is chiefly carbon dioxide and this explains why such arteries do not rupture so frequently as we might expect. Premature death of parts of the body is constantly occurring, for example, baldness, teeth. One may be vulnerable to one and another to another type of injury or bacilli. Syphilis is mainly a conjoined trait or infection and greatly predisposes to tubercle. Indeed, a syphilitic patient may be regarded as a prematurely aged one in spite of a good constitution, because there is always the possibility of sequels or parasyphilis, general paralysis, etc.
