276 Rev. P. B. Brodie on the Lias at Fretherne Tiear Newnham, 



I may here add, that some years since I obtained from a spe- 

 cimen of Lias clay from Gloucestershire some minute fossils 

 which may be enumerated with the above, viz. a Cristellaria and 

 a Vaginulina, which were associated with the Spirillina infima 

 and a few Cytheres. 



I am, dear Sir, yours very truly, 



T. Rupert Jones.

I miist now draw your attention to certain gravel beds round 

 Gloucester, which have not been sufficiently or accurately ex- 

 amined, and which I hope some of our Members will shortly un- 

 dertake to do. They are evidently of different age ; one of the 

 most recent appears to be the alluvial deposits on the banks of 

 the Severn, of which the following section in descending order 

 affords an example, and was given me by Mr. Edwards, one of 

 the engineers of the Gloucester and Chepstow Railway.

The above section was taken close to the Severn at Westgate 

 (Over) Bridge. No shells are mentioned, but the thickness of the 

 deposit is worthy of notice. The gravel round Gloucester is 

 mainly composed of rolled fragments of Oolite and debris of 

 Lias, and was evidently derived from the Inferior Oolite and 

 Lias adjacent. Some pretty Oolitic Corals may be found in it, 

 and occasionally bones and teeth of Elephant, Horse and Deer, 

 but these are very scarce. During the excavations for the Great 

 Western Railway at Stroud, many fine remains of Elephant, Rhi- 

 noceroS; Horse, Deer, and Ox were procured from the gravel, and 

 several of these are now in the collection of our friend and col- 

 league Professor Buckman. The summit of Wainlode Hill is 

 capped by a bed of pebbles called the Northern Drift, and is 

 chiefly made up of rolled and rounded pebbles of ancient rocks
