axis. The specimen measures 9 cm. in length, and 

 the axis is about 3 cm. in diameter, giving off a branch 

 equally big. The petrifying medium is locally firm, 

 and probably part of the tissue would show well in 

 microscopic sections. "Woburn Sands.

V. 5438, V. 5433 ad. A small twig 1-5 cm. in diameter, /ro cm. 

 long. The decorticated axis shows the woody texture. 

 Sections a-d in transverse, radial, and tangential 

 directions are all so badly preserved that specific 

 identification is impossible. A few cells in the trans- 

 verse section prove its coniferous nature. Among the 

 innumerable granules scattered through all the sections, 

 some are strongly suggestive of fungal spores. Lower 

 Greensand ; Woburn.

V. 5448. Irregular wedge (10x5x3 cm.) of secondary wood, 

 entirely decorticated and showing the woody texture. 

 The piece is knotty and irregular in structure, probably 

 part of a good-sized trunk. It is somewhat iron- 

 stained, and would probably show its tissue fairly well 

 it' sections were cut from it. 



Transferred from the Botanical Dept. 



V. 5458. A curved splint of teredo-bored secondary wood, 

 14x5x-cm. Tho wood is completely decorticated, 

 and shows the woody tissue externally. The material 

 is somewhat iron-stained, and would probably show its 

 tissue fairly well it' sections were cut from it. Lower 

 Greensand; Woburn. 



Transferred from the Botanical Dept. 



V. 5480, V. 5489. Two parts of the same specimen. Secondary 

 wood riddled by a mass of teredo-borings, so that no 

 woody tissue is preserved, the wood remaining only 

 as a brown film in the sandy matrix. Kentish Kajr;
