3. That the remaining specimens be disposed of in such a way as the Council may 



direct. 



4. That the Council be authorized to expend, either out of capital or income, so 



much as may be necessary to carry these resolutions into effect. 



The following amendment was moved by Sir Henry Howortb, 

 F.R.S., and seconded by Professor W, Boyd Dawkins, F.R.S. : — 



That in the opinion of this Meeting the time has now come when this Society 

 shall transfer its collections to some other museum. 



The amendment was put, and there voted for it 22, against 19. 



The amendment was therefore carried, and on being again put 

 as a substantive resolution there voted for it 26, against 19. 



The amendment was therefore declared carried as the resolution 

 of the meetius:.

"The Igaeous Rocks and Associated Sedimentary Beds of the 

 Tortworth Inlier." By Professor Conwy Lloyd Morgan, F.R.S., 

 F.G.S., and Sidney Hugh Reynolds, Esq., M.A., F.G.S. 



It has long been known that igneous rocks occur in the district 

 under consideration, but opinions are divided as to their intrusive 

 or contemporaneous character. Evidence is here brought forward 

 to show that the igneous rocks form two bands, the lower inter- 

 bedded with Upper Llandovery strata and the upper overlain by 

 Wenlock, and that both bands are probably contemporaneous lavas. 



The igneous rocks appear at two horizons, both in the Charfield 

 Green district and also in the district which includes Avening 

 Green, Damery, Micklewood, Daniel's Wood, etc. At Charfield 

 their general run is north-north-west and south-south-east, and the 

 upper band is associated with a bed of calcareous ash. The ash 

 contains lapilli, felspar-crystals, quartz-grains, small shaly patches, 

 and fossils, cemented by calcareous matter. The fossils, determined 

 by Mr. Cowper Reed, probably indicate the Wenlock age of the rock. 

 The associated trap would thus seem to be interbedded — a con- 

 clusion strengthened by its uneven surface and highly amygdaloidal 

 character. 



At Daniel's Wood the higher bed of trap is overlain by limestones 

 which contain Wenlock fossils, and underlain by rocks with Upper 

 Llandovery fossils. The dip of the rocks appears to indicate the 

 existence of an anticline. The rocks underlying the trap-band of 

 Damery Quarry are not seen, but above the trap are rocks bearing 

 Upper Llandovery fossils. This trap occupies a large area near 

 Woodford Farm. The same band of trap at Middle Hill underlies 

 an ash-bed in which fossils of Upper Llandovery age have been 

 found. The rocks, as a whole, follow the north-eastern and northern 

 boundaries of the Bristol Coalfield.
