These experiments were made upon living frogs, as well as upon the
separated legs, and in both cases the results obtained were very
similar to those observed on the employment of some form of artificial
electricity. In some of these observations, Galvani was anticipating
ideas that became current truth in electrical science only many years
after his time. In his observations upon the effects of lightning, he
was forestalling Franklin's works to a certain extent. Both of these
great scientists, however, had been anticipated by a clergyman in
Austria; whose work attracted very little attention, however, because
he was not in touch with the scientific bodies of the day. The
demonstration of the identity of ordinary terrestrial artificial
electricity and the lightning was in the air, as it were, and many
workers, as is usually the case with any great discovery, came very
close to it, and deserve at least a portion of the credit for it.
It is almost needless to say, many of these experiments with lightning
thus conducted by Galvani were not without an element of serious
personal danger. Not long after this time a Russian savant, Richman by
name, while repeating Franklin's experiments with the kite, was struck
dead by the charge received from his apparatus. Galvani, however,
{124} devoted himself only in passing to the physical problems
involved, and kept always in view the physiological aspects of the
problem of animal electricity; and, accordingly, made a series of most
interesting observations on the ray fish or torpedo, as it is
sometimes called, the fish which gives electrical shocks. His idea was
to demonstrate that the shocks felt when this animal is touched are
really due to sparks of electricity similar to those which can be
obtained by artificial means. This had never been determined, and
Galvani succeeded in showing the presence of sparks exactly as if the
animal were one of the apparatuses by which the sparks of frictional
electricity are developed. At this time this seemed surprising enough.
Galvani also endeavored to demonstrate that the electricity in the
electric torpedo differed only in degree, but not in quality, from
certain electric manifestations that he had noted in the bodies of
other animals, especially the frog. His idea always was to show the
existence of a natural animal electricity, by means of which some of
the complex mechanism of life was accomplished. He seems to have had
some notion of the theory that has been suggested often enough since,
and is not yet entirely disproved, that there is some very close
relationship between nerve impulses and the electric current. In this,
of course, he was far ahead of his time, and utterly unable to make
absolute demonstration, because of the lack of proper apparatus.
