 GEOGRAPHIC SITUATIONS. 



The geographic situations (Loca geograpliica) 

 of extraneous fossils are the countries or places 

 where these bodies have been observed to occur- 

 and are either particular or general f. 



1 . The particular ( Loca specialia ) are the indi- 

 vidual quarries, mines, &c. from which the reli- 

 quium described has been collected. 



2. The general (Loca generalia) are the re 

 gions, kingdoms, or provinces, in which the de- 

 scribed reliquium is found. 



Obs. The particular geographic situation of an 

 extraneous fossil, when known, should always be 

 carefully noted. 



f The geographic situation of a reliquium answers nearly to the 

 ioca natalia plantarum, the native places of plants, or their 

 habitat, as it is commonly, but improperly, called This, how- 

 ever, in Botany, includes the soil (solum) as well as the region 

 (regio. v. Phil. Bot. p. 263. 264.) in which the plants grow In 

 the description of a reliquium, it will always be necessary to par- 

 ticularize the soil or geological situation in a separate clause, as 

 this frequently forms a note of distinction to the species or its 

 order, and is at all times of moment in a mineralogical point of 

 view while the geographic situation is scarcely ever characteristic
