. Contributions to practical physiology and pharmacology. Physiology; Pharmacology. Fig. 44. Tracings taken with automatic cut-out keys. In each instance the current was gradually increased and decreased. A. Hand form. B. Pendulum spring form. C. Pendulum mercury Fig. 45. Diagram of circuits in automatic duplex keys. K and K', primary and secondary keys. A pendulum closes K' before K, thus short-circuiting the closing induced current. K' is opened before K, thus permitting the opening induced current to flow through the stimulating circuit, in which the tissues are interposed in series.
