pi] of the circulation through the aperture in the hydro-kinetic analogue.

The law of the mutual force in our model, however, is not the simple Newtonian law, but the much more complex law of the mutual action between electro magnetswith this difference, that in the hydro-kinetic model in every case the force is opposite in direction to the corresponding force in the electro-magnetic analogue.

Only a few of those within the pranic kinetic belts reached the etheric.

Were it not for this fundamental difficulty, the hydro-kinetic model gas would be exceedingly interesting; and, though we could scarcely adopt it as conceivably a true representation of what gases really are, it might still have some importance as a model configuration of solid and liquid matter, by which without elasticity the elasticity of true gas might be represented.

If, however, we connect the perforated bodies with circulation through them in the hydro-kinetic system, by jointed rigid connecting links, we may arrange for configurations of stable equilibrium.
