A Stupy OF THE SAVAGE WEAPONS AT THE CENTENNIAL EXHIBITION. By Ed- 
ward H. Knight, A. M., LL. D., 8vo.; pp. 85. 
We are indebted to Professor Otis T. Mason, of Columbian College, Wash- 
ington, D. C., for this volume, which comprises simply an account of one class 
of objects s\ own at the Centennial Exhibition at Philadelphia in 1876, 
Inasmuch as there was no concurrence of design on the part of the various 
exhibitors from all parts of the world in presenting these specimens of savage 
weapons, and they were mainly thrown in, as it were, with other objects, as curi 
osities, it is highly creditable to Doctor Knight that he has been able to classify 
them and illustrate so well by them the ethnology of the tribes formerly using» 
them. ‘There are nearly one hundred and fifty engravings, representing the 
weapons of all nations in all stages, while the text is graphically descriptive of all. 
People who have any taste for ethnological studies, will be much pleased and 
instructed by a perusal of this work.
