    PulveTTUCLcheT^s iTupts, ifi the ConstvuGtiou of JElectTic Chaius, ^cinds, ^c, which a springy character is given to the belt or article to which the plates are attached by the lips ct, h, it also permits of the belt or other article being folded or rolled up without fear of one plate becoming disconnected from the other. The plates in figures 3 and 4 are so arranged that the upper row can be folded over and upon the lower ones, 5 so that by laying a film or sheet of moist fibre or tissue between the folds the elements will be excited independently from the skin and be caused to act like a voltaic battery chain or band. Tigure 5 is another modification of the form of the plate C, Z, both of which have a tongue or projecting lip c, d, at the corner which lays 10 upon or overlap one another to establish and preserve voltaic contact in each separate element or battery; the elements may however be connected to form a continuous band by either of the foregoing means. Pigure 6 shows a series of plates C, Z, with tongues passed into and through the loops of ,a fabric so that the points project from the same 15 side as on that which the plates are arranged, which loops may be formed by additional or by stronger threads being used in the weaving at the proper places or in the usual threads, or the threads for the loops may be introduced by the sewing machine or by hand as desired. The plates C and Z in this Pigure are shown as being lapped and soldered 20 together, the lapping and soldering having been effected when the plates were in strips and before they were stamped or cut out to form plates of the required sizes, the tongues being formed at the lapping to give strength and rigidity at those parts. I have spoken of fabrics, and it will be understood that felted, woven, knitted, or fabrics otherwise pre- 25 pared are equally applicable for securing the plates to or to form a lining as desired. The fabrics may be coated or impregnated with a solution of any acidulated liquor or body to assist the exciting action of the perspiration thrown off from the body. The parts of the fabric which are not covered by the plates may have an adhesive substance such as 30 one of those I have before referred to or a substance analogous to them by which the chain, band, or other article can be caused to adhere to the flesh with sufficient tenacity to hold it in place, or the plates themselves may be more or less coated with such or an analogous substance for the same purpose so long as the electrical or galvanic action upon the parts 35 affected is not interfered with. I have in Pigure 7 represented one article of dress called a chest protector. This is shown as having metal beads or tinsel plates sewn on
