THE MODERN MALADY; or, Suf- 

 ferers from ' Nerves.' 



An introduction to public consideration, 

 from a non-medioal 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 the principal 

 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.
