Various rates of rapidity of motion in this primary ether, producing various numerical combinations of positively and negatively electrified particles, result in the formation of what we know as the different chemical elements, and thus explains the phenomena of their combining quantities, the law by which they join together to form new substances only in certain exact numerical ratios.

From the first movement in the primary ether to solid substances, such as wood or iron or our own flesh, is thus a series of vibrations in a succession of mediums, each denser than the preceding one out of which it was concreted and from which it receives the vibratory impulse.

This is in effect what physical science has to tell us.

But to get further back we must look into the world of the invisible, and it is here that psychological study comes to our aid.

We cannot, however, study the invisible side of Nature by working from the outside and so at this point of our studies we find the use of the time-honored teaching regarding the parallelism between the Macrocosm and the Microcosm.
