Peeks AGE. 
SINCE 1858, the year in which appeared Mr. Darwin's 
famous book, the literary as well as the scientific world has 
been deluged with works—great and small—on the subject 
of the Origin of Species. Notwithstanding, however, the 
great number of works that have been published in Eng- 
land, Germany, France, and Italy treating of the Develop- 
ment Theory, the Origin of Man, etc., there appears to be 
still a great deal of misunderstanding in reference to these 
subjects. It did not seem, therefore, superfluous to bring 
together a condensed view of the evidences for the theory 
that the animal and vegetal worlds have been very grad- 
ually developed or evolved, as distinguished from the 
hypothesis of their sudden special creation. We have 
endeavored to place before the reader, in as popular a 
manner as possible, the most important generalizations in 
reference to the structure of plants and animals, their 
petrified remains, and mode of development, and to point 
out how the theory of the Evolution of Life follows from 
the/ acts of Anatomy, Geology, and Embryology. While 
we have little new to offer to those who are familiar with 
the works of Lamarck, Darwin, Wallace, Spencer, Owen, 
Huxley, Hooker, Lyell, Haeckel, Gegenbaur, Buchner,
