My experiments were to study the reflex effects resulting from stimulation by constant galvanic currents applied to an afferent nerve of the hind limb. The main points of enquiry have been: (1) the relation between reflex excitation and inhibition of the decerebrate tonus of the vasto-crureus; (2) whether the “excitation formula” (Pflüger’s law) holds good in mammalian afferent nerves; and (3) whether there is continuous excitation during the passage of the current through an afferent nerve. The reflex effects thus produced in the extensor muscle are complex and various, and are difficult to analyse without accurate knowledge of the results obtainable in the peripheral nerve-muscle and in the flexor reflex preparation. A few experiments were therefore made with these preparations, since the exact data required could not be obtained from the literature.
