One of the statements you hear most frequently is that drugs can never remedy disease, or help in remedying it. Now, I abhor the drugging system of the orthodox medical men; I have talked with them, and heard them talk with one another, and I know that they will mix up half a dozen different substances, in the vague hope that some one of them will have some effect. Even when they know definitely the effects they are producing, they are in many cases merely suppressing symptoms. On the other hand, however, it is a fact that medical science has had for a generation or two a specific which destroys the germs of one disease in the blood, without at the same time injuring the blood itself. That disease is malaria, and the drug is quinine. Of course, the way to avoid malaria is to drain the swamps; but you cannot do that all at once, nor can you always screen your house and stay in at sundown. When you first go into a country, you have no house to screen, and some emergency will certainly arise that exposes you to mosquito bites. So you will need quinine, and will be foolish not to use it, and know how to use it. Recently medical chemists discovered another remedy, this time for syphilis. It is called salvarsan, and while it does not always cure, it frequently does. In laboratories today men are working over the problem of constructing a combination of molecules which will destroy the germ of sleeping sickness, without at the same time injuring the blood. If they find it, they will save hundreds of millions of lives. I do not see why we cannot recognize such a possibility, while at the same time making use of physical culture, of diet and fasting. When the manuscript of this book was sent to the printer, there appeared in this place a paragraph telling of the work of Dr. Albert Abrams of San Francisco, in the diagnosis and cure of disease by means of radio-active vibrations. As the book is going to press, the writer finds himself in San Francisco, attending Dr. Abrams' clinics; and so he finds it possible to give a more extended account of some fascinating discoveries, which seem destined to revolutionize medical science. If I were to tell all that I have seen with my own eyes in the last twelve days, I fear the reader would find his powers of credulity overstretched, so I shall content myself with trying to tell, in very sober and cautious language, the theory upon which Abrams is working, and the technic which he has evolved.
