regarding the limestones of the Bradford-Abbas district or the clay 

 of Eype cliff. 



Several Continental geologists, however, commence the Bathonian 

 with the Cadomensis-zone. To this idea the presence of Parhinsonits 

 and other facts gives considerable support. 



VI. — On the Continuitt of the Kellaways Beds over extended 



ABEAS NEAB BEDFORD, AND ON THE EXTENSION OF THE FuLLERS' 



Earth Works at Woburn. By A. C. Cameron. [Communicated 

 by permission of the Director-General of the Geological Survey.] 



IN this paper further evidence is submitted from different parts 

 of the country of the continuity over extended areas of the 

 Kellaways Eock above the Lower Oxford Clay. Several fine ex- 

 cavations, the result of railway enterprise, have afforded sections 

 of these beds in places where their presence was only inferred before. 

 More than the usual thickness is indicated by records recently obtained 

 from deep sinkings and borings in the Midland districts, especially 

 the Bletchley boring of 1886-7. 



The extraordinary concretionary stones noticed in Wiltshire by 

 Smith as characterizing this formation, and quarried away years ago 

 at Kellaways for road-stone, jut out in the Valley of the Churn, near 

 Cirencester, and stand about in clusters in the Valley of the Ouse at 

 Bedford like gigantic fungi. The plane of separation of the Upper 

 Oxford and the Kellaways in Bedfordshire is formed by a shelly cal- 

 careous band in contact with a shelly cap to the concretionary stones. 

 Where this plane is a broken one there is no development of con- 

 creted rock, and the lowest sediment of Upper Oxford clay is loamy, 

 passing down into Kellaways sand. Above the calcareous band 

 there is sometimes an indurated seam of sandy marl, breaking into 

 conical forms ; the product, apparently, of stalactitic infiltration. 

 Pits are opened at the outcrop of the Kellaways (a persistent stratum 

 in the Ouse Valley) and are carried down through the Lower Oxford 

 (selenite clay), Cornbrash and Cornbrash clay to Great Oolite lime- 

 stone, which is quarried for lime-burning ; the ' lam earth,' the 

 loamy portion of the Kellaways, being mixed in the mill with the 

 Lower Oxford, which is dug for brickmaking. Excellent sections, 

 showing the above series, are to be seen. 



Observations on the extensions of the Fullers' Earth Works at 

 Woburn Sands, with some description of the beds, are given, and 

 the mining industry now springing up is commented on. 



VII. — The Mastodon and Mammoth in Ontario, Canada. By 

 Prof. J. HoYEs Panton, M.A., F.G.S. 



THE writer in this paper gives a complete description of the 

 remains of a Mastodon discovered (1890) in a marl bed near 

 Highgate in the Province of Ontario, Canada, and also the remains 

 of a Mammoth found under similar conditions near Shelburne in the 

 same Province (1889).
