The dynamo-electric generator simply draws the dynamic caloric from
the air or earth, or both, and confines it in an insulated path. Now
if that path be a No. 10 wire, the conduit may be sufficient to permit
the caloric to pass without increasing the molecular velocity of the
metal to an appreciable degree, but if we cut the No. 10 wire and
insert a piece of No. 40 platinum wire in the path, the amount of
caloric flowing through the No. 10 wire cannot pass through the No. 40
wire, and the resistance so caused increases the molecular velocity of
the No. 40 wire to such degree as to exhibit the phenomenon of
incandescence, and this is the incandescent electric light. And if we
consider the carbon light, we find that the current of caloric, in
passing from one pencil to the other, produces a molecular velocity of
luminosity in the adjoining atmosphere, and in addition a portion of
the carbon is consumed, which sets free an additional amount of
caloric, at a very high velocity, hence the intensity of the carbon
electric light is largely due to the dynamic caloric unlocked from the
pencils, and thus we find that the electric light produced by either
method is due to the action of dynamic caloric.
Taking this theory based upon physical science, and the facts which we
know pertaining to electricity, I conceive that caloric exists in two
conditions.
