What these irresolute dabblers in "medical fads" need most of all is to be inoculated with good, sound common sense, but until some method is discovered for the accomplishment of that psychological feat, they will continue to run hither and thither after every new remedy, dallying with all, and deriving benefit from none. Here is the testimony of an intelligent man who realizes that the cure of a chronic disease must necessarily be a gradual process: "I was a great sufferer from kidney disease of long standing. The doctors and the various remedies recommended for this complaint afforded me no relief. I have now used your treatment for nearly six months. It is working wonders. While I am not yet entirely cured, I am a great deal better than I was, and am sure, with the rate of progress made, in six months more I shall be entirely cured." Perseverence in the treatment will achieve results that seem little short of miraculous to those accustomed to the "hit or miss" methods that have so long been in use. And best of all, the benefit attained will be permanent, for the system being thoroughly cleansed, and kept so, nothing but fresh, firm, healthy tissue is formed, so that after a year's conscientious treatment the person practising it will be practically a new being. PART V. PRACTICAL HYGIENE. Of all the dangers by which we are menaced, none is so greatly to be apprehended as ignorance. This is especially true with reference to health. The majority of people fall easy victims to disease, simply through ignorance of the fundamental principles that govern health. It is because they do not rise superior to this ignorance concerning the health of their bodies that they become the prey of the unscrupulous charlatans who thrive upon the maladies of humanity, and the patent medicine vendors whose specious advertisements beguile them of their money. The humiliating part of it is that these same imposters (in a large majority of cases) possess but little more knowledge of these subjects than their dupes, but are absolutely devoid of conscientious scruples. It behooves every intelligent individual to see that this reproach is lifted from him. Knowledge is held to be a valuable possession in every department of life; but in no instance will it yield greater returns for the investment than in the field of hygiene--in learning how to keep well. It must not be imagined that because the treatment previously described is such a wonderful curative and preventive of disease that nothing more is necessary that all other hygienic measures can be ignored. These bodies of ours were given us for a nobler purpose than to be the sport of our caprice or neglect. It is our duty to treat them as a divine trust.
