2 PROCEEDINGS OF THE GEOLOGICAL SOCIETY. 



The Secretary announced thafc an oil-painting of some Members 

 of the Geological Section of the British Association Meeting, held at 

 Newcastle-on-Tyne in 1838, painted by the late T. H. Gregg, Esq., 

 had been presented to the Society by his daughter. 



The PRESiDFmT referred to the sad loss which the Society had 

 sustained since the last Meeting, through the death of the late

The President reported that Mr. L. Belinfante had been tempo- 

 rarily appointed ,by the Council to the Office of ilssistant-Secretary.

[Abstract.] 



The Author, having given reasons why the presence or absence 

 of pipe-clay, false-bedding, or mica is not a criterion for the Lower- 

 Bagshot Sands, independently of stratigraphical considerations, 

 proceeded to bring forward new evidence from well-sections, clay- 

 pits recently opened, and excavations, bearing upon the reading of 

 the country between Wellington-College and Wokingham Stations, 

 as put forward by him in 1887 (Q. J. G. S. vol. xliii. and figure 1 

 of the paper). 



In particular, the Author stated that in Messrs. Monckton and 

 Herries's section of the Middle-Bagshot Beds, along the railwa)' 

 (Q. J. G. S. vol. xlii. p. 407), the dip to the south is excessive and 

 misleading ; and he brings forward new evidence to show that 

 the assumption that the sands at Wokingham represent the base of 

 the series cannot hold good. 



He has now actual data for the gradients of the clay-beds, and 

 the thinning-out of both the Lower (fluviatile) Sands and of the 

 Middle green-earth series ; the latter, when taken into account, 

 bringing the clays in the Wokingham outlier into the same horizon 

 with the basal clays and brick-earths of the Middle Group to the 

 south. The clays at California brick-yards are also shown to be in
