1. The interaction of vaso‐motor responses taking place during stimulation of various afferent nerves has been studied and compared with similar interactions taking place in reflex contractions of skeletal muscles. 2. The phenomenon of effacement taking place during intercurrent stimulation of two afferent nerves is described. This effacement is sometimes complete. 3. Effacement is also observed during the interaction of a sensory and an efferent vaso‐motor nerve. 4. The phenomenon of augmentation in vaso‐motor reflexes is described and critically examined. 5. The mechanism of effacement is a peripheral one. In this respect the phenomenon of vaso‐motor effacement differs from that of occlusion observed in muscular spinal reflexes. The peripheral overlap of vascular areas involved is so great that it is impossible to determine whether a central overlap also exists. I wish to express my gratitude to Sir Charles Sherrington for advice and criticism, and for the facilities afforded in his department for the performance of these experiments.
