d. They also occur in the beds of rivers, f and 



e. In most situations, where mineral or other mat- 

 ter is daily accumulating^ f 



f. The conservata are found in all states, between 

 that, in which actual decay, or the separation of 

 the constituent principles of the original, takes 

 place, and that, in which further decay is prevented, 

 either by a new combination in the remaining prin- 

 ciples, by an impregnation with mineral particles, 

 or by some other natural process, incident to these 

 bodies. 



g. The animal conservata most common are such 

 remains, as are most rare in the petrified state 

 i. e. the bones of mammalia and fish and shells of 

 the same genera ( often of the same species ) as those 

 found in the neighbouring seas. 



h. The most common vegetable conservata are 

 wood and other parts of trees. ^^ 



i. The conservata are more frequently referable 

 to plants and animals now existing than the petri- 

 ficata yet 



t The bones of quadrupeds, wood, moss, &c. 



ft Among the conservata found in situations of this kind, are 

 to be reckoned the bones of animals deposited in the banks of 

 rivers, &c., wood and other parts of trees preserved in our bogs 

 and morasses, and lastly, perhaps, turf or peat itself, (of which 

 such bogs &c., generally consist) as long as it retain its vegetable 

 nature and structure. 



fft Frequently such as are known in the recent state.
