Eyeless Sight: A Study of Extra-retinal Vision and the Paraoptic Sense, by Jules Romains (Louis Farigoule), translated by KC Ogden, 251 pp, New York, NY, GP Putnam's Sons, 1924. Dr Romains has conceived the idea that the skin has retained its supposedly primitive function of reacting to light, and that this function may be cultivated to such a degree that the skin may become a useful organ of sight. He bases his theory on the biologic fact that in our earliest progenitors the outer covering of the body, or "skin," performed all the sensory functions of the body—reacting alike to light, heat, sound and touch, and therefore by a stretch of imagination these forms could be said to see with their skins.
