The finer degrees of the stimulating current are obtained with the rheocord. The secondary leads are connected with the secondary key leads and with the secondary division of the current controller. The circuit may be broken to the controller by means of a contact screw. Also, the circuit to the keys may be broken by another contact screw^ By opening both these screws the secondary keys are isolated, so they may be used for a battery current. A pair of binding posts on the key leads serves for such connection. Commutator connectors (see Fig. 38) are pro- vided. When not in use, they are attached to the back side of the Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Guthrie, Charles Claude, b. 1880.
