256 THE HUMAN BODY. 



In a friendly adieu we wave our good wishes through space 

 to him who is the object of them; but when it expresses 

 enmity, by a brusque movement we sever every tie. The 

 open hand is carried backward to express fear or horror, as 

 well as to avoid contact; it goes forward to meet the hand of 

 friendship; it is raised suppliantly in prayer toward Him 

 from whom we hope for help; it caresses lovingly the downy 

 cheek of the infant, and rests on its head invoking the bless- 

 ing of Heaven; in a word, the touch, real or imaginary, is 

 constantly adding a feature to the physiognomy. 



THE END,
