Our skins let us know whether the air is wet or dry, whether surfaces are wet without being sticky or slippery(滑). From the light pressure, we can know how deeply a finger is pushed into water at body temperature, even if the finger is in a rubber glove which keeps the skin completely dry. Many other animals, with highly sensitive skins, appear to be able to learn skill more about their environment. Often they do so without employing any of the five senses.
By examining the abilities of other members of the animal kingdom, we come to realize that a human being has far more possibilities than those are made use of. We give not enough care to ever so many of our senses in paying particular attention to the five major ones. At the same time, a comparison between animals and man draws attention to the limitations of each sense. The part of the spectrum(光谱) seen by color-conscious men as red is non-existent for honey-bees. But a bee can see far more in flowers than we, because the ultra-violet(紫外线) to which our eyes are blind is a stimulating part of the insects spectrum, and for honey-bees at least, make up a separate color.
