6. " Note on ' Cone-in-Cone ' Structure." By John Young, Esq., 

 E.G.S. 



[Abstract.] 



This note was written with the object of calling the attention of 

 the Geological Society to some very fine and remarkably interesting 

 examples of " Cone-in-Cone " structure. 



The author, after referring to the views of previous writers on 

 the origin of this structure, proceeded to describe the interesting 

 examples of it which occur in the coalfields of Ayrshire and Ren- 

 frewshire. He pointed out that the structure is generally exhibited 

 in bands overlying beds of fossils. 



7. "A Geological Sketch of Quidong, Manaro, Australia." By 

 Alfred Morris, Esq., C.E., E.G.S. 



[Abstract.] 



This district is situated about 250 miles S.S.E. from Sydney. The 

 cliffs about the Bombala river are about 100 to 120 feet high, and 

 formed of very dark limestone, crowded with fossils, chiefly Penta- 

 merus. In the author's opinion there has been great disturbance in 

 this region, resulting in a complete change in the course of the 

 river Bombala and a displacement of the shale. A mass of ferru- 

 ginous sandstone has also been upheaved. This, as well as the 

 other rocks in the neighbourhood, contain Upper Silurian fossils. 

 It appears to have been altered by heat. Pockets of galena and 

 copper are occasionally found in the district, and there is a vein of 

 haematite. Clay-slates occur as well as the above rocks, the cleavage 

 being generally vertical or nearly so. 



The following specimens were exhibited :-

 Dawkins, in illustration of his paper.

 illustration of his paper. 



Specimens of " Cone-in-Cone " Structure, exhibited by John 

 Young, Esq., in illustration of his paper.
