220 DESCRIPTIVE CATALOGUE 



V. 5431 d. Tangential section of the above. In this the height 

 of the rays and the presence of rosin-containing 

 elements in the rays can he well seen. 



I have searched through the manuscript catalogue of 

 the Sloane Collection and have not found any refer- 

 ence to the specimen ; there are, however, several 

 different series of numbers and several specimens 

 labelled 229. The evidence for the view that this is 

 part of the original Sloane Collection is an old Libel 

 with the number and another old label with the 

 locality, both firmly attached to the specimen. 

 Lower Grccnsand ; Woburn Sandy, Bedfordshire. 



(?) Sloane Coll., no. 2i'!>. 



V. 4876, V. 4876 a-c. Figured, PI. XX, fig. 2. This large 

 specimen is part of a branch, now 30 cm. long and 

 about 7x5 cm. in diameter. It was fully decorti- 

 cated before petrifaction, and must, have boon not loss 

 than 20cm. in diameter when alive. It bears t\v<> 

 old labels, which seem to prove that it was one of the 

 original Sloane Collection (see V. 



V. 4876 a. Transverse section of the above, which is illustrated 

 in PI. XX, fig. 2. The preservation is rather imper- 

 fect, but the annual rings of the wood can be well 

 seen. 



V. 4876 b, C. Longitudinal radial and tangential sections of 

 the above. Preservation is poor and does not show 

 the finer details. The character of the rays and resin- 

 parenchyma can just be made out, and agree with the 

 type-species so far as can be seen. 



Lower Greenland; Woburn Sands. (?) Sloane Coll., no. 643. 



V. 5446. Two wedge-shaped pieces of secondary wood, 

 3-5x2x7 cm. and 2-5 x 1'5 x 5-5 cm. Externally 

 the texture of the wood shows well in the hard 

 silicified medium. The specimens are somewhat iron- 

 stained, as is usual from the AVoburn beds.
