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.

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 CYRUS THOMAS. lc°. $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 

 (Waiam 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 batik 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 fingle 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 contribu'lon 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-bulldlDg age.'-'— iV^. I''. Sun. 



"An Interesting pebper."'— Christian Union.

" * The Tornado' Is a popular treatise on an Impor- 

 tant province of meteorology. In which science, the 

 author, Professor Hazen ot the United States Signal 

 Service, may be regarded as an expert.'' -Philadel- 

 phia Ledger.

 ities as a thinker and as a writer are too well and 

 too widely known to require couxraent."— Public 

 Opinion.
