MEANS OF THE EXPRESSION OF THE EMOTIONS. 291 



The actions and attitude of a helpless man are, in every 

 one of these respects, exactly the reverse. 



BLUSHING. 



Blushing is the most peculiar and the most

Emotions, from passion, but it would require an over-

 Dr. Burgess remarks, by any physical means — that is, by 

 any action on the body. It is the mind which must be 

 affected. Blushing is not only involuntary, but the wish
