H and I are two similar and equal magnets fixed in the brass plate, A, C, very near each other, but not touching. K and L, two more, fixed in the brass plate, B, D. Now, as the north pole of one magnet repels the north pole of another magnet and attracts the south, and, inversely, the south pole of one magnet repels the south pole of another and attracts the north, so the south pole, I, "attracts all the north ones at E, and the north pole, H, repels all the nor in ones at M. In like manner, K attracts at N and L repels at O, and by this means the whole machine, E, F, is expected to move perpetually around.

     Now this would be all lovely if magnets did not attract in more than one direction. Many American inventors have tried the same principle over and over, only to find their wheel standing still, and have then sighed for some medium which, interposed between a magnet and its armature, would prevent attraction while thus interposed.
