The history of this plant might afford a practical answer to 

 such as sneer at the pursuits of the botanist, and are con- 

 tinually asking Cui bono $ For it grew neglected, until 

 Dr WITHERING, a botanist, made known its virtues, 

 and gave to medicine one of its most valuable auxiliaries. 

 It is most beneficial in dropsical and inflammatory com- 

 plaints, and in diseases of the heart and of the lungs ; but 

 great caution is required in its ii'se.
