Vlll PREFACE. 
SO much success in his examination of the 
evidences of Design in the mechanical 
structure of the corporeal frame of Man, and 
of the inferior Animals which are placed with 
him on the present surface of the Earth. 
The myriads of petrified Remains which 
are disclosed by the researches of Geology 
all tend to prove, that our Planet has been 
occupied in times preceding the Creation of 
the Human Race, by extinct species of 
Animals and Vegetables, made up, like 
living Organic Bodies, of " Clusters of Con- 
trivances," which demonstrate the exercise 
of stupendous Intelligence and Power. They 
further show that these extinct forms of Or- 
ganic Life were so closely allied, by Unity 
in the principles of their construction, to 
Classes, Orders, and Families, which make 
up the existing Animal and Vegetable King- 
doms, that they not only afford an argument 
of surpassing force, against the doctrines of 
the Atheist and the Polytheist ; but supply 
a chain of connected evidence, amounting to 
demonstration, of the continuous Being, and 
of many of the highest Attributes of the One 
Living and True God.
