assisted by art. This inmost bark appears 

 to be, in some respects, very similar to the 

 periosteum in the animal body, and might 

 not improperly be called the periligneum. 

 It resists putrefaction to a high degree, and 

 remains sound long after all the rest of the 

 bark is completely rotten. It possesses a 

 considerable degree of elasticity, which is 

 the cause of its remaining entire when the 

 inner bark rends, and by this quality yields 

 to the circulation of the sap. 



By transverse bark, I mean that external 

 thin membrane whose fibres run across the 

 tree, by some called Epidermis. 



When I use the word peeling, it is to be 

 understood I mean taking off the outer bark 

 as above defined.
