 Belgian Loess, and the beds h as the equivalent of the Belgian 

 Sables de Campine.

The following communications were read: — 1. "On the Lias 

 Outliers at Knowle and Wootton Wawen in South AYarwick shire," 

 &c. By the Eev. P. B. Brodie, M.A., F.a.S, 



The author gave a description of the Liassic outliers at Knowle 

 and Wootton in South Warwickshire. At Knowle, eleven miles S.E. 

 of Birmingham, the Lower Lias is represented by limestone and 

 shales containing Ammonites planorhis, Saurian remains, Ostrea, 

 llodiola, &c. ; below these beds with Ammonites planorhis, dark 

 shales were seen resting on the New Bed Marl ; amongst the shales 

 occurs a micaceous sandstone with Fullastra arenicola, which else- 

 where prevails lovv^ down in the series, in close connexion with the 

 bone-bed. The greater outlier at Wootton Park, near Henley, ex- 

 hibited more clearly the succession of the deposits, from the beds 

 with Pecten Valonien&is up to the limestone with Lima giga7itea, &c. 



2. " On the History of the last Geological Changes in Scotland." 

 By T. P. Jamieson, Esq., P.a.S. 



The history of the last geological changes in Scotland, as given 

 in this paper, was divided into three periods, namely, the Pre-glacial, 

 the Grlacial, and the Post-glacial, 



The absence of the later Tertiary strata from Scotland leaves the 

 history of the Pre-glacial period very obscure ; but the author con- 

 sidered it in some degree represented by some thick masses of sand 

 and gravel (apparently equivalent to the Eed Crag of England) on 

 the coast of Aberdeenshire ; and he stated that there were indica- 

 tions of the Mammoth having inhabited Scotland during this 

 period. 



The Glacial period was divided into three successive portions, 

 namely, (1) the Period of Land-ice, during wliich the rocky surface 

 was worn, scratched, and striated, and the boulder earth or glacier- 

 mud Avas formed; (2) the Period of Depression, in which the 

 glacier-marine beds were formed ; and (3) the Period of the Emer- 

 gence of the land to which belong the valley-gi'avels and moraines, 

 and during which the final retreat of the glaciers took place.
