other under tlie rougli rock, and in the two places above mentioned, 

 and in the Low Moor coal fields. 



Here we found also, Anthracosia, or brackish water shells, Goniatites 

 Zisteri, Aviculo-pectens, and other shells and fish remains. It must not 

 be supposed that the Anthracosia, though found in the same heap, 

 came from the same bed as the Goniatites and Aviculo-pectens, for 

 while the former lies below the Hard-bed coal, the latter lies on the 

 top of that coal. 



Passing over the hill and examining the debris at the mouth of each 

 shaft, we found nothing of importance till we came to No. 6 

 shaft, where we found the " cone-in-cone " again, which had been 

 derived from a considerably higher horizon than that referred to above. 

 This fact was new to us, and it was clear that there are at least two 

 beds of " cone-in-cone " in our Halifax coal strata. It appears to 

 occur (judging from the depth of this shaft — 50 yards) about 40 to 

 50 yards, below the flag-rock. It occurs also at some distance above this 

 rock, in the Low Moor coal strata. We also found Anthracosia, which 

 appears to have come from nearly the same level as the "cone-in-cone.'' 



The section exposed at the entrance to the tunnel at Hole Bottom, 

 on the Clayton side of the hill, is a very instructive one. There, a 

 fault crosses the line in a south-east and north-west direction, with a 

 down-throw to the east, and accompanied by several minor ones. 

 The dyke which divides the rocks is about a yard wide, and is filled 

 with fragments derived from the sides. It forms part of the great 

 fault which runs from near Bradford, by Clayton, to Denholme Gate, 

 and north-westwards into the Millstone-grit country. It has a down- 

 throw to the north-east at Clayton of about 73 yards, and at Den- 

 holme Gate of 150 yards or more. 



The day was all that could be desired, and having spent a very 

 enjoyable afternoon, we returned by Queensbury to the meeting-place, 

 at the Queen's Head Inn, with our bags full of fossils. 



At this meeting Messrs. Cockroft, Binns, and Spencer exhibited 

 specimens, obtained since last meeting, chiefly during the afternoon 

 ramble over Queensbury Tunnel, viz. : — fine specimens of cone-in-cone, 

 from two different horizons in the shafts, Anthracosia rohusta or 

 brackish-water mussels, Goniatites Listeri (two varieties), Nautilus 

 Rawsoni, Orthoc&ras cinctum (very large specimen), Aviculo-pecten 

 papyraceus, Possidonia Trigonia, Modiolopsis, fish remains — bones, 

 teeth, and scales. Plants : Sigillaria, Stigmaria ficoides, Lepidodendron 

 Harcourtiif Halonia regulare, Ulodendron minor, &c.
