1. Every person is susceptible to magnetic influence, and also capable of successfully resisting a degree of it equal to his own magnetic power, and of sustaining a higher degree, so far as to be little affected by the magnetism of another.
2. Every person is capable of communicating animal magnetism to others; but if the person to whom he attempts to communicate it possesses as high a degree of the same power as he does, no distinct manifestation of the influence will be perceived.
3. Persons possess at different times different degrees of magnetic power, and also different degrees of impressibility. Consequently the same class of experiments, by the same persons, will sometimes be successful and sometimes fail.
4. Experiments with the sick, if judiciously conducted, seldom fail to afford relief; and if disease should be entirely of a nervous character, permanent recovery will usually follow.
5. If susceptibility to animal magnetism is a quality or power of the nerves themselves, it is always improved and rendered more acute and distinct by exercise. If the susceptibility is the result of disease, it generally diminishes as the patient recovers. In other words, it requires more magnetic power to influence a healthy organ than it does to influence a diseased organ.
6. The most important faculty in an operator is his ability to concentrate his mind. For want of this ability, many who possess a high degree of animal magnetism are very poor operators, when they should be most successful The power of concentration of mind may be greatly increased by persevering practice.
7. By judicious scientific experiments in animal magnetism, every depressed part of the body may be brought into a condition of natural activity, independent of the action of other organs, and may be forced to perform its particular function in a natural manner without interfering with other organs. That is, it is possible to stimulate a depressed organ without over-stimulating organs that are working naturally.
8. Through animal magnetism the seat and character of disease may be ascertained and the proper means of restoration indicated. Also, the improvement or decline of the patient's condition may be noted from day to day.
1. Do not operate upon persons who are seriously affected in the vital organs unless you are yourself strong and in good health; otherwise, through your own impressibility, you may receive from them the symptoms of their diseases, instead of communicating to them the beneficial influences of your own system.
2. In treating diseased persons, if you wish to stimulate or arouse to activity any special organ that is depressed, while directing your magnetism to that organ, always keep one hand near the antagonistic organ of the patient or of a sound and healthy bystander.
3. If operating upon persons who are passionate by nature or easily angered, be careful not to excite their organs of combativeness, destructiveness, etc., unless provided with assistance to control them. If by accident or design you should happen to excite these organs, and the subject should become outrageous, touch the organs of benevolence and reverence and the excitement will subside by equalizing the nervous action.
