Not illustrated. 1867 Excerpt: ...as in our hands the testimony on this point has always resulted negatively., Sparks may be given to, or drawn from, any part of the body, but they can be most readily obtained on a dry surface; for if the skin or the patient's clothing is moist, the discharge is thus dissipated, and we get no spark. Electrization by this means has been greatly esteemed by some experienced physicians for its success in curing chorea, hysteria, colds, rheumatisms, some forms of paralysis, and neuralgia. While the patient is sitting in the insulating chair, and charged positively, sparks can be drawn from the body by applying any conductor near to the patient. If the person is being charged negatively, the same manoeuvre will give sparks to the spot where it approximates. In either case there is a vivid flash of light, which, so far as it goes, is a streak of lightning. This is always attended with the sound of a sharp crack, as the negative electricity instantly combines with the positive. The sensation of a spark on the skin is like that of a slight prick of a pin; and this pricking sensation is in proportion to the length of the spark, as well as according to the sensibility of the part. Hence it is necessary to proceed gently with this by holding the ball of the conductor against the skin, or very close to it, at the commencement, until the patient gets a little accustomed to its sensation, when the discharger may be carried farther off to give longer and stronger sparks, and produce a greater effect. Giving sparks does not have so much effect locally as drawing the less frequent but longer sparks; for this latter produces a local accumulation of high-tension electricity in the skin and sub-adjacent tissues near the spot where the ball approaches the body. Here is the simp...
