accomplished at once, very much can be done now, and more ultimately, by 

 getting right in all these particulars. And public hygiene, carrying out these 

 principles in ample drainage, supplying pure water, cleaning streets, and sup- 

 pressing all nuisances, may aid greatly in this work. And when a generation 

 shall have been raised up with such habits and without the hereditary predispo- 

 sition to this and other kindred diseases, children not inheriting it, properly 

 cared for by their parents and obeying all the laws of life and health, may be- 

 come in a great degree secure from the ravages of diphtheria, and hence of 

 other putrid diseases. And as the body is the instrument of the mind, physical 

 disease may not only be eradicated in the main, but the intellectual and moral 

 powers of mankind will become proportionally elevated \ and thus humanity may 

 in a measure approximate Divinity, and become more nearly " allied to angels 

 on the better side." Let us labor for this, then, as not only involving the 

 physical, but also in an equal degree, the intellectual and moral well-being of man-

The Young Folks' CvcLOP-ffiDiA of Persons and Places, by John D. Chaplin, 

 Jr., pp 936, 8vo; New York; Henry Holt & Co. ; $3.50; for sale by M. 

 H. Dickinson. 



The success of "The Folks' Clyclopedia of Common Things," by the same 

 author, encouraged him to undertake the book under consideration, which is de- 

 voted to accounts, written in a style readily comprehensible by children, of noted 

 persons and places, both real and fabulous, thus supplementing the first, which 

 was devoted to things in nature, science and art. Everything has been done in 

 the way of illustration, description, pronunciation of words, etc., to make this 

 work a most valuable one for school children and families, and in our judgment 

 the effort has been far more than ordinarily successful. In looking through its pages 

 we are surprised to note the amount of labor that has been bestowed upon it 

 in collecting from all reliable sources, interesting and valuable information upon 

 all possible subjects, historical, geographical and biographical. Teachers who 

 can induce their scholars to purchase this book, will save themselves great labor 

 and will contribute largely to the information as well as pleasure of their pupils.

The fact, that by far the most numerous and perfect bird fossils have been
