On prolonging the excitation there is a slow return to the position of rest, which is sometimes reached during the closure of the circuit, in other cases only after it has been opened again ; but the return is seldom perfect.

On prolonging the excitation there is a slow return to the position of rest, which is sometimes reached during the closure of the circuit, in other cases only after it has been opened again ; but the return is seldom perfect. There is usually a permanent. diminution of the muscle current (negative after-effect), the degree of which depends on the strength of the previous excitation. The immediate inference as to the meaning of the backward swing of the magnet during tetanus would be, that there was a persistent diminution of the longitudinal current, continu- ous throughout the period of excitation. In view, therefore, of the known properties of the physiological rheoscope, which reacts mainly at the rise or disappearance, or sudden variations in density of a current, it might be expected that the leg serving.
