    tiplying wheel The other three glass wheels are twenty-eight inches each in diameter, fixed alternately between their revolving fellows, and are continually stationary, being held by insulating bearing* and screw damps at their outer edges. Each of these latter wheels have three large holes cut in them, one circu- lar and large enough at the centre to allow the axis of the revolving plates to pass through without touching them, while the other two oval opening*, cal led windows or cells, are at opposite sides of the horizontal diame- ter. Fixed on these glass wheels at opposite sides near the edges of the windows are pieces of stiff paper, covered with gold foil, notched on their edges where they appear just within the side of the windows, so as to lean a little over toward* the nearest revolving plate, as accumulators. Near the outer or other side* of each of the re* voicing plates, in rather wider spaces, and opposite the gold point* in the edge of the windows in the alternate stationary plate*, are horizontal brass arras with metallic oombt and gold fringes, reaching to lav tween the glass plates, for taking up the electricity and leading it on to the two main conductor*. The other bra;** arm.* with gold fringe*, that brush the glass wheels, and are seen to be fixed at an angle of forty- five degrees are for maintaining the reliable position of the positive and the negative pole; at the same time, together with the small piece of eat skin next the rear glass wbe«l, they also act to insure tint ** initial charge in starting the machine; all of which is inclosed in a large plate glass case, with a strong mahogany frame ami doors, made as nearly air tight a* feasible. The two main conductors, 1*. and N., project out forward by piercing the front glass plate of the case, some two feet apart. The positive pole is on the right hand, and the negative is on the left, as we face the front of the machine. To these are attached two small glass con- densers, with a connecting rod between them. Outside the glass case, and near the outer ends of
