feet.” Amongst the strata struck in Bates’ shaft, portion 170, Wellington 
Yale, was an indurated carbonaceous shale with, leaves forming a part of the 
upper lead. The leaves are referable to a sapindaceous plant : — 
CuPANITES SeLWYNI, Ett. 
A branch of the Rocky Creek Lead known as the Gem Lead, in the 
Parish of Lome, has to some extent yielded fossil leaves. The alluvial 
matter consists of ‘pipeclay, associated with magnesite, and overlying well- 
worn quartz sand, and small pebbles of quartz-porphyry. In the pipeclay 
a graminacious plant is found, called by Ettingsliausen — 
BaMBUSITES AIITHROSTYLINUS, Ett. 
Professor Ettingsliausen includes the whole of the plants under the 
general term Eocene ; but it must be borne in mind that great changes took 
place between the deposition of the two fossiliferous deposits represented by 
the pipeclay of the Old Hose Valley Lead and the bed cut in Witherden’s 
Tunnel on the one hand, and that found at the much higher level in Eox 
and Partridge’s workings, between Bose Valley and the Bed Hill, on the 
other. The lowest drifts represented by the former were covered with a 
considerable thickness of the older dark green dense basalt, and then the 
flow denuded into deep valleys. A second flow of basalt then took place in 
what is now the neighbourhood of Box’s shaft, covering up the denuded 
surface of the older. Both these lava Hows were in their turn excavated, and 
the newer drifts laid down in the valleys thus formed. It will be seen from 
this that between the times at which the two lloras grew, no less than five 
distinct geological changes took place. These phenomena are excellently 
shown on Section 2, Vegetable Creek Deep Lead, attached to Mr. David’s 
work previously referred to. 
Very little stratigrapliical information is to hand respecting the other 
localities mentioned in the Second Part of this Memoir. At Newstead, near 
Elsmore, and on the Macintyre River, near Invcrell, plant remains, and seeds 
accompanied by fresh -water shells, occur in a concretionary ironstone, 
apparently an earthy limonite, overlaid by basalt. The species arc the 
following : —
