of organic forms, can understand or sympathise with thd 

 pleasures of the solitary discoverer. 



The following then is a description of several new forms 

 discovered in this way at Stevenson's Bend : — 



No. 1 is a very handsome concostate leaf of the Cinnamon 

 type. See Cinnamomum polymorphum figured by Lyell from 

 Heer's work on the (Eningen beds. The figure there given, 

 though not identical, closely resembles No. 1 in the form of the 

 venation, and in the elliptic shape of the leaf. It is 3^- 

 inches long, and 1J inches broad. I have only seen the one 

 impression, and may therefore consider it comparatively rare. 



No. 14#. is the impression of a small, costate, possibly, 

 lanceolate leaf. Primary veins straight, numerous, parallel, 

 running out and upwards, at an acute angle to the extremity. 

 Size when perfect, say lh long and § broad — not common. 



No. 6o. seems to have been a lanceolate shaped leaf, with 

 venation somewhat similar to that of the leaf of the Solarium 

 nigrum — common. 



No. 3, pinna of a fern very similar to the pinnae of the 

 existing Lomaria lanceolata so common in this neighbourhood. 

 Not common. 



No. 5 and 6a represent beautifully distinct impressions of 

 the portions of fronds of one of the filmy class of ferns. It 

 resembles Trichomanes or Adiantum in the delicate, spread- 

 ing, repeatedly furca.te veins, but differs from most of the 

 species in either, in having a somewhat prominent wavy 

 midrib. It must have been a very graceful fern, and would 

 if now existing prove a formidable rival to the favourite 

 " Maiden hair." 



No. 4. I was particularly struck with the scale-like appear- 

 ance of this impression. 



The markings bearing so close a resemblance to the stripped 

 surface of the Banksia, I resolved to make a closer comparison. 

 I found by taking a wax impression of the inside face of the 

 dried bark of the existing Banksia, that it was indentical in 

 every respect with the fossil cast No. 4. This, with the 

 knowledge that the Banksia in a silicified forms occurs else- 

 where with the pine, prepared me for the discovery of these 

 woods associated together in the original matrix at Corra 

 Lynn. 



Breadalbane Lignite. 



I have so frequently referred to this deposit that it may be 

 desirable to point out its position and relation with greater 

 exactness. The stratum of lignite has now been ascertained 

 to be between 3 and 4 feet thick. It is generally very impure
