theories of modern science, and have done much to further the idea that
life is present everywhere, and that there is no such thing as dead matter.
He bases his work upon the theory that the best and only true test for
the presence of life in matter is the response of matter to external stimulus.
Proceeding from this fundamental theory he has proven by in-numerable
experiments that so-called inorganic matter, minerals, metals, etc., give a
response to such stimulus, which response is similar, if not identical, to the
response of the matter composing the bodies of plants, animals, men.
He devised delicate apparatus for the measurement of the response to
the outside stimulus, the degree, and other evidence being recorded in
traces on a revolving cylinder. The tracings or curves obtained from tin and
other metals, when compared with those obtained from living muscle, were
found to be identical. He used a galvanometer, a very delicate and accurate
scientific instrument, in his experiments. This instrument is so finely adjusted
that the faintest current will cause a deflection of the registering needle,
which is delicately swung on a tiny pivot. If the galvanometer be attached
to a human nerve, and the end of the nerve be irritated, the needle will
register.
Prof. Bose found that when he attached the galvanometer to bars of various
metals they gave a similar response when struck or twisted. The greater the
irritation applied to the metal, the greater the response registered by the
instrument. The analogy between the response of the metal and that of
the living muscle was startling. For instance, just as in the case of the living
animal muscle or nerve matter, the response becomes fatigued, so in the
case of the metal the curve registered by the needle became fainter and
still fainter, as the bar became more and more fatigued by the continued
irritation. And again, just after such fatigue the muscle would become rested,
and would again respond actively, so would the metal when given a chance
to recuperate.
Tetanus due to shocks constantly repeated, was caused and recovered.
Metals recorded evidences of fatigue. Drugs caused identical effects on
