"The book is good, thoroughly good, and will long 

 remain the best accessible elementary ethnography 

 in our language." — The Christian Union. 



"We strongly recommend Dr. Brinton's 'Races 

 and Peoples' to both beginners and scholars. We 

 are not aware of any other recent work on the 

 science of which it treats in the English language." 

 —Asiatic Quarterly. 



"His book is an excellent one, and we can heartily 

 recommend it as an introductoi-y manual of ethnol- 

 ogy."— T/ie Monist. 



"A useful and really interesting work, which de- 

 serves to be widely read and studied both in Europe 

 and America." — Brighton (Eng.) Herald. 



"This volume is most stimulating. It is written 

 with great clearness, so that anybody can under- 

 stand, and whiie in some ways, perforce, superficial, 

 grasps very well the complete field of humanity."— 

 The New York Times. 



"Dr. Brinton invests his scientific illustrations and 

 measurements with an indescribable charm^ of nar- 

 ration, so that 'Races and Peoples,' avowedly a rec- 

 ord of discovered facts, is in reality a strong stim- 

 ulant to the inaagination." — Philadelphia Public 

 Ledger. 



"The work is indispensable to the student who re- 

 quires an intelligent guide to a course of ethno- 

 graphic VGOu^ing.^^— Philadelphia Times.

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 Ctrus THOMAS. 12°. $1. 



Dr. Thomas has already presented to the public 

 some reasons for believing the Cherokees were 

 mound-builders, but additional evidence bearing 

 on the subject has been obtained. A more careful 

 study of the Delaware tradition respecting the Tal- 

 legwi satisfies him that we have In the Bark Record 

 (Walam Olum) Itself proof that they were Chero- 

 kees. He thinks the mounds enable us to trace back 

 their line of migration even beyond their residence 

 In Ohio to the western bank of the Mississippi. The 

 object Is therefore threefold: 1. An Illustration of 

 the reverse method of dealing with prehistoric sub- 

 jects; 2. Incidental proof that some of the Indians 

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

 the light of the mound testimony. This work will be 

 an Important contribution to the literature of the 

 Columbian discovery which will doubtless appear 

 during the coming two years. 



"A valuable contribution to the question, 'Who 

 were the mound-builders? ' '--New York Times. 



"Professor Cyrus Thomas undertakes to trace 

 back the evidences of a single Indian tribe into the 

 prehistoric or mound-building age."— iV. Y. Sun.
