and intensities--that velocity being what is commonly called the speed of
light, 190,000 miles per second. Quite probably this may be true of koilon,
and if so it must also be capable of communicating those waves to bubbles
or aggregations of bubbles, and before the light can reach our eyes there
must be a downward transference from plane to plane similar to that taking
place when a thought awakens emotion or causes action.

In a recent pamphlet on "The Density of Æther," Sir Oliver Lodge remarks:--

"Just as the ratio of mass to volume is small in the case of a solar system
or a nebula or a cobweb, I have been driven to think that the observed
mechanical density of matter is probably an excessively small fraction of
the total density of the substance or æther contained in the space which it
thus partially occupies--the substance of which it may hypothetically be
held to be composed.

"Thus, for instance, consider a mass of platinum, and assume that its atoms
are composed of electrons, or of some structures not wholly dissimilar: the
space which these bodies actually fill, as compared with the whole space
which in a sense they 'occupy,' is comparable to one ten-millionth of the
whole, even inside each atom; and the fraction is still smaller if it
refers to the visible mass. So that a kind of minimum estimate of ætherial
density, on this basis, would be something like ten thousand million times
that of platinum."

And further on he adds that this density may well turn out to be fifty
thousand million times that of platinum. "The densest matter known," he
says, "is trivial and gossamer-like compared with the unmodified æther in
the same space."
