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.

THE AWIERTcAN RACE: 



By DANIEL G. BRINTON, M.D. 



"The book is one of unusual interest and value." — 

 Inter Ocean. , ^ ^ 



" Dr. Daniol G. Brinton writes as the acknowledged 

 authority of the subject '^—Philadelphia Press. 



" The work will be of genuine value to all who 

 wish to know the substance of what has been found 

 out about the indigenous Americans "—Nature.

 successful education of the powers of observation."

RACES AND PEOPLES. 



"T'ue book is good, thoroughly good, and will long 

 remain the best accessible elementary ethnography 

 in our language "—The ■hristian Uni n 



"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 introductory 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."— .BrtgAton fEng.) Herald. 



"This volume is most stimulating. It is written 

 with great clearness, so that anybody can under- 

 stand, and while in some ways, pertorce, superficial, 

 grasps very well the complete field of humanity." — 

 The New York Times. 



'Dr. Brmton 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 imagination."- Philadelphia Public 

 Ledger. 



"The work is indispensable to the student who re- 

 quires an intelligent guide to a course of ethno- 

 graphic maivng."— Philadelphia Times.

"The story Is a piquant, good-humored, entertain- 

 ing narrative of a canoe voyage A neater, prettier 

 book is seldom seen."— Literari/ World 



" This is a sprightly narrative of personal inci- 

 dent. The book will be a pleasant reminder to 

 many of rough experiences on a frontier which is 

 rapidly receding."— Boston Transcript. 



" 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 stj le, constitute the claims of h'- "'^^'- 

 book to present attention."— rftc Dial.

V'".

THE WINNIPEG COUNTRY; 



OR. , 



ROUGHING IT WITH AN ECLIPSE PARTY.! 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 wM-k 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.
