THE MODERN MALADY; or, Suf-ferers from I Nerves.'

An introduction to public consideration,from a non-medical point of view, of a con-dition of ill-health which is increasinglyprevalent in all raiiks of society. In thefirst part of this work the author dwells, onthe errors in our mode of treating Neuras-thenia, consequent on the wide ignorance ofthe subject which still prevails: in the sec-ond part, attention is drawn to tlje vrincipalcauses, of the malady. The allegory formingthe Introduction to Part I. gives a brief his-tory of nlervous e:xbaustion an(l the modes oftreatment which have at various tiimes beenthought suitable to this most paiulful and try-inlg disease.
