PATHOLOGY. 



Firm and long pulse of health. 



Hard pulse. 



Hard and long pulse of hypertrophy of left ventricle. 



The soft pulse. — Of this kind of pulse several varieties are 

 described. In the small soft pulse, towards the close of pro- 

 gressive exhaustive diseases, the impulse of the heart is slight, 

 the tension of the arteries diminished, and the volume of blood 

 small. In some cases of anosmia, however, or of slow action of 

 the heart, or of great relaxation of the arterial coats, or of these 

 conditions combined, there may be a soft full yet feeble pulse. 

 It is readily known by the feebleness of the impulse, and by the 

 artery yielding readily to pressure.
