12 PETRIFACTIONS AND THEIR TEACHINGS. CHAP. I. 



The lowermost shelf is devoted to silicified stems of trees 

 allied to the Palms (called Psaronia by M. Cotta), many 

 of which are polished in transverse sections, to show the 

 structure. 



On the top of this case there are portions of large stems 

 of fossil Palms, from Chemnitz, and from the State of Ohio. 



D. [4.] This case is chiefly allotted to the fossil Club- 

 mosses, or Lycopodites, some slabs of which are very fine : 

 the fruits of these trees, termed Lepidostrobus, are arranged 

 on the lower shelves. There are many fine, specimens in 

 ironstone nodules, from Colebrook Dale. 



E. [5. A, B, c. D.] The Sigillarice and Lycopodiacece occupy 

 the upper division ; the lower contains fossil plants allied to 

 the Cycadeacece (labelled Asphodelece) : among these are Stern- 

 bergia ; and Claihraria, Endogenites, and Draccena, from the 

 Wealden formations of Sussex and Kent. 



On one of the shelves there are a few fruits from the 

 London Clay of the Isle of Sheppey, belonging to plants 

 allied to the Palms (Nipa) ; with leaves and stems of Palms 

 from other localities. 



Above cases D and E, are placed a silicified stem of a tree 

 from the Isle of Portland ; and several large specimens of 

 Endogenites erosa, from, the Wealden strata at Hastings. 



In the narrow compartment of this case, on the left of the 

 doorway, there is a fine palm-leaf (Palmacites Lamanonis), 

 from the Tertiary strata of Aix, in Provence : (formerly in 

 the author's collection). 



On the left of the doorway, on the ground, there is part 

 of a petrified stem of a Palm, from the Valley of the Nerbudda, 

 in India. 



On the right, a slab of Lias limestone, from Dorsetshire, on 

 which is lying, in relief, a leafless branch, four feet long, of a 

 coniferous tree. 



F. [6. A, B, c, D.] The shelves of the upper division con- 

 tain fossil Coniferce (A and D), and many fine specimens of 

 the vegetables termed Stigmarice, under the general name of 

 EuphorUacew (B and c). There are several interesting fossil 

 Coniferce,^ Pinus, Araucaria, Thuytes, Voltzia, &c. and fir- 

 cones from the Crag of Norfolk. 



The lower division comprises examples of leaves, fruit, and 

 stems, of extinct plants allied to the Cycadece (Pterophyllum)
