Show Touch includes several senses. Thus there are spots on the skin ' which feel heat only, spots which I feel only cold, spots which feel only pain, spots which feel only, pressure and spots which feel, tickling. These spots are supplied I with nerves capable of doing only one particular duty. The sensations sensa-tions of the skin are grouped by physiologists into three kinds touch, pain and temperature. The skin which covers a scar has only one kind of sensation. It can feci neither pressure (touch ! proper) nor temperature, but; perceives pain very acutely. The ' tongue is the most sensitive of j all parts to touch, the forehead j nd elbow to heat or cold. We ' only dream sights and sounds, i We never dream tastes or smells. 1 If we dream of a flower garden, j we see the flowers, but do not ! smell them. If we dream of a dinner, din-ner, we see the dishes, but do not' taste them. j |
