. II. RELICS. Phenomena. 5 



A. 3. The general phenomena are such, as are 

 common to both kinds of organic remains. These 

 are the following. 



a. Reliquia, or extraneous fossils, have been 

 found in every quarter of the known world. 



b. They are met with embodied in the hardest 

 rocks and stones, as well as in the softer materials, 

 of which the surface of the earth is composed 



c. They are not, however, equally common to 

 all rocks and mineral substances 



d. Granite, sienite, gneiss, micaceous shistus, 

 some species of limestones, &c., never contain or- 

 ganic remains, (v. . HI. Soil, &c. ) 



e. In rubblestone, breccias, gypsum, trap, &c.j 

 they rery rarely occur 



f. Most limestones, sandstones, and clay-strata, 

 abound with them. 



g. The rocks, &c., in which reliquia are never 

 found, constitute the highest mountains known. 



h. Those which rarely hold, as well as those 

 w 7 hich abound with extraneous fossils, form also 

 mountains, but of an height f generally inferior to 

 the preceding. 



on these bodies in their mineral beds ; this leads to an inquiry into 

 their Origin, and the Time and Mode of their introduction into 

 the fossil kingdom. 



f According to an observation of Mr. Kirwan's, no extraneous 

 fossils are embodied in the stone of mountains higher than eight or 

 nine thousand English feet above the present level of the sea. This 

 is, however, disputed by many geologists.
