224 CONIFEROUS WOOD. 



V. 706. A fairly large piece of wood with patches of resinous 

 material or amber traversing the mass longitudinally ; some of 

 these suggest the presence in the wood of large groups of 

 parenchymatous tissue, such as Conwentz has described as 

 " abnormes Holz-parenchyrn " in the case of Pinus succinifera 

 (Gopp.) l from the North German amber beds. The microscopic 

 structure is very imperfectly preserved. Ecclesbourne. 



Rufford Coll. 



V. 707. Wood partially converted into lignite. Ecclesbourne. 



Dawson Coll. 

 V. 713 (Dawson Coll.], V. 2233, V. 2237. 



Specimens of wood showing little or no internal structure. 

 Ecclesbourne. Rufford Coll. 



V. 2247 and V. 2247. In the latter specimen the structure 

 is fairly well preserved ; annual rings are distinct, but less so than 

 in V. 2304 (Pinites Ruffordi}. 



V. 2326. A specimen of wood which has undergone com- 

 paratively little alteration. Ecclesbourne. Rufford Coll. 



38374. Small piece of lignite. Fail-light. Mantell Coll. 



[Spirang-ium Jug-leri (Ett.). In the Eufford Collection 

 there are several exceedingly well-preserved specimens of this 

 fossil which merit careful examination ; but if we accept the view 

 that they are the eggs of fishes and not plant structures, this is 

 not the place for any descriptive account of them. For informa- 

 tion as to the nature of Spirangium reference may be made to
