ford examples of calcareous organic substances. 

 v. p. 40. 47. &c 



b. 100. THE INFLAMMABLE ORGANIC SUBST. 

 (substantia organ, inflammabilis) which occurs in 

 extraneous fossils is, for the most part, either carbo- 

 naceous or bituminous. 



Obs. Conservata of vegetable bodies, as of leaves, 

 wood, &c. afford the principal examples of inflam- 

 mable organic substances, v. p. 44. 47. Note, p. 

 50, &c. 



B. 101. THE MINERAL SUBSTANCE (sub- 

 stantia mineralis) of an extraneous fossil, is the 

 matter which has taken place of that which existed 

 in the original body ; or, if it once existed as a con- 

 stituent part in the original, is the matter which has 

 lost the organic arrangement of its particles, v. 

 p. 51-66. 



The mineral substance of a reliquium is either 

 earthy, inflammable, or metallic ; rarely saline. 



a. 102. THE EARTHY MINERAL SUBST. (sub- 

 stantia miner, terrea) is, for the most part, calca- 

 reous, argillaceous, or siliceous ; sometimes barytic 

 or magnesian-\. 



Obs. The simple earths, variously mixed and 

 combined with saline, inflammable, or metallic mat- 

 ter, constitute earths and stones in their natural 



f The substances in which the strontian, jargonic, and some 

 other earths, newly discovered, occur, have not, as yet, been found 

 as constituents of extraneous fossils.
