THE MODERN MALADY; or, Saf- 

 ferers from ' Nerves.' 



An introduction to public consideration, 

 from a non-medical point of view, of a con- 

 dition of ill-health which is increasingly 

 prevalent in all- ranks of society. In the 

 first part of this work the author dwells on 

 the errors in our mode of treating Neuras- 

 thenia, consequent on the wide ignorance of 

 the subject which still prevails: in the sec- 

 ond part, attention is drawn to tlie orincipal 

 causes of the malady. The allegory forming 

 the Introduction to Part I. gives a brief his- 

 tory of nervous exhaustion and the modes of 

 treatment which have at various times been 

 thought suitable to this most painful and try- 

 ing disease.
