The hallerians' fundamental tenet held that muscular movements were produced by a mechanical force force, different from life and from the nervous system, and which operated beyond consciousness. The activity of this function could be controlled in dead and dissected animals by touching a metal knife to the muscle fiber or by a spark being discharged on them. The electricity operated only as a stimulus of irritability, and it was irritability which was the one, true cause of the contractions.
