 Principles of Geology.] Arch. Sci. Phys. Nat. t. Ivi. pp. 96-106, 

 plate 1. 

 Discusses in succession: — 1. The pentagonal system, which he styles 

 a geological heresy now rapidly dying out. 2. The notion of hard and 

 fast lines between successive formations ; " Let us seek," he says " the 

 passages between formations, not lines of separation." 3. The method 

 of representing the outlines of ancient seas by means of present outcrops, 

 which he shows to be absurd. 4. The theory of the indefinite diver- 

 gence of species, taking as a starting-point characters of an inferior 

 order. Believes rather in successive specific creations. Varieties are 

 as useful to geologists as species ; but the two must not be confounded.
