<.364 Mr W. Nicors Observations on Fossil Trees. 



bbcWith regard to the two specimens of petrified wodd from the 

 ^tertiary formation of the Isle of Sheppy, I have only to remark, 

 that they both belong to the coniferous family. One of them 

 displays the concentric rings surrounding the pith very, dis- 

 tinctly, but throughout the greater part of the mass there are 

 only fragments of the reticular texture to be seen intermixed 

 with calcareous spar, in the form of stellular radiated concre- 

 tions. In the centre of many of these concretions there are a 

 ^ew meshes of the net-work of the wood, and which have pro- 

 bably disposed the calcareous matter to assume its present form*. 

 These specimens, when in the woody state, have been pene- 

 ti^ted by wprina iaa ipanner similar to what takes place at the 

 .present day, and the cavities so formed have been filled with 

 calcareous spar and sulphuret of iron. Yours faithfully, . ,

Account (^ tM , Discovery of Bone Caves in WeIlingto?i Valle^ 

 about 210 miles west from Sydney in New Hollands ^id* 



De liANG of Sydney *, at present in this country, having conv- 

 municated to us the following particulars, in regard to the x%^ 

 markable bone-caves of New Holland, we hasten to lay them 

 before our readers, as they are highly interesting in a geological 

 view. A description of the collection of bones from these caves, 

 mentioned in the following communication, w^ill be given in our 

 next Numbw. Among these remains of a former mammiferoii^ 

 creation;^ are bones of an animal very much exceeding in si?e 

 any of the existing races in New Holland. . 



Sir, Sydney, 9.\st May 1830., ^. 



I beg you will allow me to inform your readers that a dis- 

 covery, which will doubtless excite very considerable interest 



• • We are delighted to learn that a College Academj'^ is about to be eu 

 tablished at Sydney. • With such a man as Dr Lang as chief, it cannot iail 

 to flourish, and prove beneficial to the Australian world.
