powerful power. Having settled in his mind this second principle, he proceeded to fix upon the details, and accordingly established the following rules of attenuation. When the article to be used is a solid, he directs one grain of it to be mixed and pulverized with one hundred grains of sugar of milk—the rubbing be continued a long time. This is what Hahnemann called dynamizing—that is, making the article powerful. When this process has been continued long enough, it is called the first attenuation. One grain is next to be taken from; and added to another hundred grains of and dynamized as in the first instance. This makes the second attenuation. One grain next to be taken from this, and added to another hundred grains of sugar, and the process continued as before. By this rule, all the attenuations are to be made. Hahnemann considered the thirtieth as the most proper for use.
If the medicine is a liquid, the first attenuation is made by adding one drop of the tincture to one hundred drops of alcohol contained in a new vial; it is then to have at least one hundred
