1. ' On the Stratigraphical, Lithological, and Palaeontological 

 Features of the Gosau Beds of the Gosau District, in the Austrian 

 Salzkammergut.' By Herbert Kynaston, Esq., B. A. 



This paper, after referring to the previous literature of the 

 subject, treats of the situation and physical aspects of the Gosau 

 Y alley, the distribution of the Gosau Beds, their stratigraphy, palge- 

 ontology, and geological horizon, and the physical conditions under 

 which they were deposited, and a comparison is instituted between 

 the Gosau Beds and the equivalent beds of other areas. The author 

 shows that Hippurites occur at two horizons in the Gosau Beds, — a 

 hippurite-limestone immediately above the basement-conglomerate 

 being characterized essentially by Hippurites cornu-vaccinum, which 

 is overlain by Actceonella- and JS J erincea-Hmestones and an estuarine 

 series, and above these is a second hippurite-limestone characterized 

 essentially by Hippurites organisans. It is pointed out that Toucas 

 similarly distinguishes two hippurite-zones in Southern Erance ; the 

 lower, characterized essentially by H. cornu-vaccinum, being placed 

 by him at the top of the Turonian System, whilst the second, with 

 H. organisans, is referred to the summit of the Senonian ; and the 

 author gives reasons for regarding the Gosau zones as the equiva- 

 lents of those of the South of Erance, in which case the Gosau Beds 

 will represent the uppermost Turonian and the whole of the Seno- 

 nian, i. e., the zones of Holaster planus, Micraster, Marsupites, and 

 Belemnitella mucronata in England, whilst the upper unfossiliferous 

 beds may be the equivalents of the Danian Beds. 



The strata are, on the whole, of shallow-water origin, and were 

 deposited in shallow bays in the Upper Cretaceous sea of Southern 

 and Central Europe, on the northern flanks of the Eastern Alps. 

 Probably towards the close of Upper Cretaceous times the southern 

 area of the Gosau District was cut off from the sea to form a lake- 

 basin in which the upper unfossiliferous series was deposited. 



2. ' Artesian Boring at New Lodge, near Windsor Forest, Berks.' 

 By Prof. Edward Hull, M.A., LL.D., F.P.S., E.G.S. 



The boring described in this paper was carried down from a level of 

 about 220 feet above Ordnance-datum, through the following beds : — 



feet 



London Clay 1 91 4 



Lower London Tertiaries J 



Chalk 725 



Upper Greensand 31 



Gault 264 



Lower Greensand 7 



The Chalk was hard, and contained very little water ; but on 

 reaching the Lower Greensand the water rose in the borehole to a 

 height of 7 feet from the surface. 



The author discusses the probability of the Lower Greensand 

 yielding a plentiful water-supply in the Windsor district.
