RACES AND PEOPLES. 
By DANIEL G, BRINTON, M.D. 
“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 introductory manual of ethnol- 
ogy.”—The 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 writen 
with great clearness, so that anybody can under- 
stand, and while 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 1 ree: 
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 reading.” —Philadelphia Times. 
Price, postpaid, $1.75. 
THE AMERICAN RACK. 
By DANIEL G. BRINTON, M.D. 
««The book is one of unusual interest and value."= 
Inter Ocean. 
“Dr. Daniel G, Rrinton writes asthe acknowledgea 
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. 
‘“©A masterly discussion, and an example of the 
successful education of the powers of observation.” 
—Philadelphia Ledger.

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 stil] prevails: in the sec- 
ond part, attention is drawn to the principal 
causes of the malady. The allegory forming 
the Introduction to Part J. gives a-brief his- 
tory of nervous exhaustion and the modes of 
treatment which have at various times been 
thought suitable to this mest painful and try- 
ing disease.
