    The current developed from the Hydro-Electric Chain is a Voltaic Primary current and its effects on the human organization very diflerent from the Secondary Magneto-Electric or Electro-Magnetic, irreg- ular and turbulent currents of the ancient apparatus. The current of a Hydro-Electric Chain invaria- bly passes in the same direction and completes the Electric Circle through the body from the Copper (gilt) pole to the Zinc pole. With these Chains all the other effects of a battery of 120 elements can be produced. The decomposi- tion of water, the precipitation of metals from solutions, galvanoplastic, galvanotyping, decomposition of metallic salts in solution, and electro-magnetic and thermical effects. All auxiliary apparatus for all these experiments may be had on applying to our office at New York. CHAIN BATTERIES TO SELL. [A.] BATTERIES IN BOXES. No. 1—Morocco: containing 2 Chains of 60 elements each ; interrupting clockwork, interrupting cylinder, conductor, with brush for mouth, ear and teeth; instrument for galvano-puncture. Price, $22,50. No. 2—Morocco : containing 2 Chains of 60 elements each ; 2 conductors, interrupting cylinder, conductor, with brush for mouth, ear and teeth ; instrument for galvano-puncture. Price, $16. No. 3—Morocco : containing 2 Chains of 48 elements each; 2 conductors, interrupting cylinder, conductor for mouth, ear and teeth. Price, $12.-50. No. 4—Morroco: containing 2 Chains of 36 elements; 2 conductors, interrupting cylinder, conductor for mouth, ear and teeth. Price, $10. [b.] BATTERIES IN POCKET-BOOKS. The form of this apparatus is as simple as possible, with regard to its size. The whole of it, with its auxiliary apparatuses, is made up in form of a pocket-book not larger than a cigar-case. It has, besides, the advantage that its batteries may be employed by leaving the Chains in the ease. [aa.] Two Chains, with their contrary poles opposite each other. [bb.] Pieces of insulating horn, to which are hooked the Chains. [cc] Metallic threads, spun over with silk, to conduct the electric current to the conductors. [dd.] A hooked wire to effect the contact of the two Chains, in order to complete the electric circle ^e figures 12 and 13). After having taken out the Chains, moistened them with vinegar, they are fixed again in the pocket- book in such a manner that the white pole of one Chain, and the gilt one of the other, are together on
