ng that a very high authority doubles several of these
numbers." Then, writing upon the definite relationship of
electro-chemical equivalents, he states, Art. 835: "Electro-chemical
equivalents are always consistent; _i. e._ the same number which
represents the equivalent of a substance _A_, when it is separating from
a substance _B_, will also represent _A_ when separating from a third
substance _C_. Thus 8 is the electro-chemical equivalent of oxygen,
whether separating from hydrogen or tin or lead; and 103.5 is the
electro-chemical equivalent of lead, whether separating from oxygen or
chlorine or iodine."

So that from Faraday's experiments we learn definitely that the
electro-chemical equivalents coincide with and agree with the ordinary
chemical equivalents according to Dalton's theory. From these
experimental results of Faraday's we therefore learn that Faraday was of
the opinion that each atom had a definite and certain quantity of
electricity associated with it; and if this be true, then, in view of
the identity of Aether with electricity, it follows that each atom must
have definite and certain quantities of Aether associated with each
atom. So that through Faraday's experimental researches we are again led
to the hypothesis enunciated by Lord Kelvin in his paper "On the
Clustering of Gravitational Matter in any part of the Universe," viz.
that all matter has an aetherial, that is, an electrical basis, and that
it is by the condensation of this electricity, and combinations of the
condensational particles, that all the various elements are formed which
compose the infinite variety of forms that constitute the entire
Universe. Here, then, it seems to me, we have the evidence which gives
to the aetherial Nebular Hypothesis (Art. 121) that experimental
evidence which places that hypothesis upon a firm and philosophical
foundation, and conclusively proves that it is possible for Aether out
in the colder regions of interstellar space to be condensed into masses
of gaseous matter, which form nebulae, and other masses in the cold
regions of interplanetary space to condense and form comets and meteors.

ART. 125. _Physical Constitution of Matter._--In Art. 31 we learned that
all matter was made up of minute parts called atoms. When these atoms
enter into combination with each other, they form the smallest particles
of elementary substances as well as compound bodies, these parti
