horny, and thus preventing impressions being 

 received by the nerves. 



The sense of touch is of the greatest use to us, 

 and enables us to know whether bodies are hard 

 or soft, solid or fluid, rough or smooth, hot or cold. 

 As the knowledge it conveys is the most accurate, 

 it is generally called in to assist the other senses ; 

 and when we are deprived of some of these, by a 

 wonderful dispensation of Providence, it supplies 

 their place. Thus, touch alone enables the blind 

 man to learn many useful arts, which we cannot 

 attempt without using our eyes. 



Though many parts of our bodies are very sen- 

 sible, the knowledge they convey is vague and 

 uncertain. It is the peculiar province of the hand, 

 furnished as it is with long and slender fingers, to 

 make us sensible of the exact nature of whatever 

 comes near us.
