life, from the remote past to the present, will not only help us to 
forecast the future, but may guide us in our duty of leaving the 
world better than we found it.” 
Here our exposition of this able work must end; anthropolo- 
gists may not agree with all of the author’s conclusions; the science 
is in its infancy, and its center of gravity is not yet settled, but it 
must prove an invaluable manual of the subject. Few errors 
appear in it; a rather saber’ one is the author’s statement on 
p. 30, that the musk o may still be hunted in the Rocky 
mountains with the siicaly bear.” This is an evident slip of the 
pen 
Know.epce!,—Under this title comes to us the first number 
of a popular scientific magazine. We welcome as many such 
Journals as there is room for; whether there is for this one, time 
will show, Judging from the first number, “ Knowledge,” will be 
more than usually popular. We can anticipate that the depart- 
ment of astronomy will be very well conducted. There are 
several valuable articles, ¢. ¢., “On science and Religion,” by the 
editor, of a mediatory character, and one on The Relation of 
Food to Muscular Work, by Dr. Carpenter ; also one on Illusions, 
by Thomas Foster, and a review of Darwin on Earth Worms. Of 
less value is a review of Delaunay’s paper on the relative charac- 
teristics of men and women, which from the style of its logic, 
appears to have been written by one of the sex it seeks to defend 
from Dr. Delaunay’s definitions, We hope for Knowledge a large 
. Share of usefulness and patronage.
