(all still smooth and polished), until we arrive at the full form of the 

 Lepidodendron. Nay more, I have found the parallel lines (channels) 

 which are on the slickens ides, also on the perfectly-formed Lepido- 

 dendra. The correctness of my views here I could prove to the 

 most sceptical. 



The discoveries still to be made on this subject are numerous and 

 important ; and I doubt not that the investigation of the coal itself 

 will soon solve the doubts hitherto existing in the comparison of the 

 coal fossils with recent plants. 



1 will merely add, that I have found quite distinctly the impression 

 of the cellular cuticle of some of these plants, which of course can- 

 not be seen in an impression on shale, the grains of the sedimentary 

 matter being as large as the surface of the cells ; but on the pasty 

 mass of coal the impression is perfect. — ^iWim^ois Journal, Nov. 1847.
