At a little distance to the east, the uppermost bed of the jurassie 

 group, in contact there with laterite, is an altered-lookiug sandstone so 

 silieious as to bear a close resemblance to quartzite, and southwards the 

 sandstones of the same Jurassic group roll up to the surface, overlaid 

 by the laterite, — the shaly and other beds beneath it being there absent 

 or less prominent. 



The occm-rence here of a small and fragmentary palaozamia in the 

 Jurassic beds is the only instance of the presence 

 of these plants which has rewarded a close search 

 all through the most easterly part of the province. It may be taken to 

 indicate either the close of the marine period, or, with probably greater 

 accuracy, an analogy to the case of the intercalation of terrestrial and 

 marine organisms in the far western part of the district which has 

 been already alluded to (p. 51). 



Another unusual circumstance is, that the section above given is 



crossed by two dykes of soft purple lava, one
