force destroys the silicic force of the glass atom, and libe- 

 rates its sodial force, to take its place upon the positive 

 conductor P. On the other side, the cushion may be regarded 

 as constituting one atom in thickness, in which the corre- 

 lative of the sodial force is destroyed by the silicic force of 

 the glass, thereby liberating the correlative of the silicic 

 force, to take its position on the negative conductor N". 

 Each conductor comports itself as a single atom, with nodes 

 at the extremities and venter at the centre ; and if conducting 

 wires s and s f be respectively attached, each acts as a single 

 wave, carrying the positive and negative forces through to 

 the reservoir R at one dash. 



When at rest, not only does equilibrium exist through the 

 diameter from every point of the cylinder, but also through- 

 out the circumference at every point of the shell; but the 

 effect of rotation upon these circumferential atoms does not 

 interfere with the diametral effect. If a circular glass plate 

 EE' (fig. 15) be adopted instead of a cylinder, a more sym- 

 metrical form may be given to the machine. The cushion 

 CC might also be attached to a circular plate; and then, 

 attention paid to the proper insulations, revolving motion 

 may be given either to the electric or the cushion, by means 

 of a strap around the rim of the circular plate, and governed 

 by a multiplying wheel. According to this fancy, one dy- 

 namical opposing wave on each side of the contact between 

 the cushion and the electric crosses to the other side of the 

 plate to which it belongs, and takes thence its route through 

 the nodes formed by the points projecting from P and 1ST 

 respectively, and onwards through the wires p and n to the 

 analysing plate or vessel E. 



13, When matter is elevated to the gaseous state, and 

 the application of heat is persisted in, the atomic radii con- 

 tinue to increase, the mass increases in bulk, the resistance 

 to compression becomes a force sufficient to set machinery 

 in motion, and work is performed (Carnot, Joule).
