The author wishes to caution the reader not to rely merely on the forms of treatment here prescribed, but to study thoroughly the principles taught in the preceding pages, until he shall have mastered them, and can judge for himself of the correctness of these prescriptions. It should be remembered, however, that the diseases here considered are viewed in their _simple_ or _uncomplicated_ states. Where complications exist, the treatment must be modified according to the judgment of the practitioner. In these instructions, it is always to be understood that the treatment prescribed is with _cords of equal length_, except when the _long cord_ is especially mentioned. In most of the local diseases here named, particularly those which are electrically _negative_, it is desirable to supplement the local treatment prescribed with occasional _general tonic_ treatment, where, in the judgment of the practitioner, it can be given without detriment to the local affection. In all treatments, the electrodes should be moistened with warm water. GENERAL TONIC TREATMENT. Take the B D current, (A D is very good), of fair medium strength. Place the sponge-roll, N. P. [Negative Pole], at the coccyx--lowest point of spine--and manipulate with side-sponge cup, P. P. [Positive Pole], from the feet all over the lower limbs to and about the hips; occupying three or four minutes, or less. Then remove the N. P., substituting for the sponge-roll the end-sponge cup, and place this upon the spine at the lower part of the neck. Now manipulate with side-sponge cup, P. P., over the trunk generally, from the lower to the upper parts; giving special attention to the spinal column by treating it somewhat more than other parts. Treat the trunk some five to eight minutes. Next, keeping the N. P. still upon the back of the neck, treat with P. P. over the hands and arms, up to and about the shoulders. Treat here two or three minutes.
