centers of the small ones, was 5'. 3" from the vial, and the middle point of the 

 trial plate 8'. 2" from vial, and that some boards forming a floor about 4 or 

 5 feet square was placed under the circles 14 inches from the ground, and that 

 a perpendicular bar of the same breadth as those of the frame was placed 

 5 inches nearer to the circles than the other, so that the distance of the center 

 of the large circle from the vial and the ground, and also the distance of the 

 nearest small circle from the perpendicular bar when they were placed at 

 36 inches distance, were diminished in about the ratio of 2 to 3*.

The wires were placed parallel to each other, horizontal and perpendicular 

 to the horizontal bar. They were touched almost close to one extremity by the 

 same wires and in the same manner as the circles in the former experiment. 



That end of the wires near the part which was touched was suspended by 

 silk, the other end was supported on waxed glass. The distances were the same 

 as in [Art. 472].
