Note 91 — REMARKS ON THE SYSTEMS OF HARTLEY AND HELVETIUS

Those of the touch admit of the greatest variety in this respect from the general diffusion of that sense over the whole body, and those which depend on hearing from the small part of the ear which is in general distinctly affected by sound at the same time. As to the taste and smell, the stimulants applied to these senses are such as for the most part to act on a large proportion of the organ at once, though only at intervals. The direction of smells is hardly distinguishable like that of sounds.
