THE MODERN MALADY ; or, Suf- 

 ' ferersfrom 'Nerves.' 



An introductiou 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 oui' 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.

" The picture of our desolate North-western terri- 

 tory twenty-five years ago, in contrast with its 

 civilized aspect to-day, and the pleasant features of 

 the writer's style, constitute the claims of his little

FOSSIL RESINS. 



This book is the result of an attempt to 

 collect the scattered notices of fossil resins, 

 exclusive of those on amber. The work is of 

 interest also on account of descriptions given 

 of the insects found embedded in these long- 

 preserved exudations from early vegetation.
