THE MODERN MALADY ; or, Suf- 

 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 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.

IV. THE CHEROKEES IN PRE-CO- 



LUMBIAN TIMES. By Cyrds THOMAS. 12°. $1. 



Dr. Thomas has already presented to the public 

 some reasous for believing the Cherokees were 

 mouud-buliders, but additional evidence bearing 

 ou the subject has been obtamed. A more careful 

 study of the Delaware traditiou respecting the Tal- . 

 legwi satisfies him that we have lu the Bark Rocord 

 (Walam Oium) itself pi oof that they were Chero- 

 kees. Ue thiijks the mounds enable us to trace back 

 their line of migration even beyond their resldei^ce 

 in Ohio to the western bank of the Mississippi. The 

 object is tberefore threefold: 1. An lllust atlon of 

 the reverse method ol dealing with prehistoric sub- 

 jects; 2. Incidental proof that some of t!ie Indians 

 were mound builders; 3. A study of a single tribe in 

 the light ot the mound testimony. This woik will be 

 an Important contribution lo the literature of the 

 Columbian discovery which will doubtless appear 

 during the coming two years. 



"A valuable contrlbu ion to the question, ' Who 

 were the mound-builders? ' "— ZVem York Times. 



"Professor Cyrus Thomas undertakes to trace 

 back the evidences of a single ludiau tribe Into the 

 prehistoric or mound-building &ge.''—N. Y. Sun. 



" Au interesting paper,"'— Christ ia7i Union.
