herefore the
aetherial basis at the same time.
In paragraph 852 of his _Experimental Researches_ Faraday writes: "The
theory of definite electro-chemical action appears to me to touch upon
the absolute quantity of electricity, or electrical power, belonging to
different bodies. Although we know nothing of what an atom is, yet we
cannot resist forming some idea of a small particle which represents it
to our mind, and though we cannot say what electricity is, so as to be
able to say whether it is a particular _matter or matters_, or mere
motion of ordinary matter, yet there is immensity of facts which justify
us in believing that the atoms of matter are in some way endowed or
associated with electrical powers to which they owe their most striking
qualities, and amongst them their chemical affinity. As soon as we
perceive, through the teaching of Dalton, that chemical powers are
(however varied the circumstances in which they are exerted) definite
for each body, we learn to estimate the relative degree of Force which
resides in such bodies; and when upon that knowledge comes the fact that
electricity, which we appear to be capable of loosening from its
habitation for a while, or conveying from place to place, whilst it
retains its chemical Force, can be measured out, and being so measured,
is found to be as definite in its action as any of those portions which,
remaining associated with the particles of matter, give them their
chemical relation, we seem to have found a link which connects the
proportion of that belonging to the particles in their natural state."
Then in paragraph 855 he writes as follows: "It seems a probable and
almost a natural consequence, that the quantity which passes is the
equivalent of, and therefore equal to, that of the particles separated,
_i. e._ that if the electrical power which holds the elements of a grain
of water in combination (or which makes a grain of oxygen and hydrogen,
in the right proportions, unite into water when they are made to
combine) could be thrown into the condition of a current, it would
exactly equal the current required for the separation of that grain of
water into its elements again."
Further, in Art. 857, he states, "I can have no doubt that, assuming
hydrogen as 1, and dismissing small fractions for the simplicity of
expression, the equivalent number or atomic weight of oxygen is 8, of
chlorine 36, of bromine 78.4, of lead 103.5, of tin 59, etc.,
