      • 1.
        Experiments have been carried out to compare the electrical responses of dried, recently excised, and living bones when subjected to stress.
      • 2.
        The effect of drying was to decrease the size of the peak voltage developed and, instead of decaying rapidly towards zero, the response became more sustained.
      • 3.
        Responses could be recorded from living bone with only minimal disturbances of the adjacent muscles.
      • 4.
        The results suggest that bone responds mainly to changes in load and that the state of the bone determines the form in which this response is recorded.
