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
