PLATE LXIII. 



Root (?) 



If this be indeed a root, as Hutton supposed, it is 

 certainly of a very different character from either of 

 the three last figured specimens. There is a certain 

 symmetry about the embranchments, and a certain 

 leaf -like form about the filaments, that might make one 

 doubt the reference. On the other hand, it is difficult to 

 say to what other department of vegetable organization 

 it may belong, especially as no signs of structure are* 

 visible. 



The figure is about one-third smaller than the original 

 drawing by Prior, which was of the natural size. 

 u The Newcastle coal-field" is all the locality given.
