yet readied by the borehole. They consist of red and mottled 

 clays and sandstones, with occasional bands of grit ; mica is very 

 abundant, and the rocks show false bedding. Microscopic crystals 

 of dolomite, and particles of galena are also present. On close 

 investigation these rocks yielded fish-remains, which Dr. Smith 

 Woodward kindly determined. They consist of scales and teeth of 

 HoloiJtycJiius and plates of BotJiriolejpis^ both characteristic Upper 

 Devonian or Old lied Sandstone fishes. There is close lithological 

 similarity between the red rocks of Southall and llichmond ; and he 

 therefore suggested that the Richmond rocks were of the same age. 

 This applies also to the rocks from Kentish Town and Crossness, 

 which in the absence of fossils were attributed by Prof. Judd to 

 the Poikilitic Series, and by Prestwich to the Devonian. It is 

 interesting to note that these Southall rocks bear little resemblance 

 to the undoubted Devonian rocks from Meux's brewery, and from 

 Turnford. They represent a shallower-water facies, and indicate 

 that under the London Basin rocks of Old Red Sandstone type as 

 well as rocks of true Devonian type occur, an association similar 

 to that found in Eussia. 



Mr. F. W. Haemee hoped that the officers of the Geological Survey 

 would not lose sight of an important boring at some ice-works 

 at Lowestoft, which, after they had been carried on intermittently 

 for some years, were abandoned on account of the unsatisfactory 

 character of the water that was met with. He had just learned that 

 operations had been recommenced. As a depth had already been 

 reached much greater than that of any boring hitherto attempted 

 in the district, it was to be hoped that information of much value 

 and importance might be gained during the further prosecution of 

 the work. 



Dr. J. AV. Evans regarded the specimens on the table as 

 an excellent illustration of the importance of the proposals put 

 forward by Prof. Watts in his Presidential Address, in favour of the 

 systematic examination by borings of the rocks below the Mesozoic 

 strata of the South-East of England. The speaker regarded the 

 discovery of typical Upper Old lied Sandstone fishes at Southall as 

 an event of the greatest interest and importance. There was 

 nothing surprising in the occurrence of the Upper Old Eed and 

 Upper Devonian lithological types in borings in the same area. 

 The latter were shown by the fossils to be of the same littoral 

 character as that with which we are familiar in North Devon 

 in the Baggy and Marwood and Pilton Beds ; while the former 

 closely resemble the Pickwell Down Beds which immediately 

 underlie the Baggy and Marwood Group, and are of a pronounced 

 Old Red Sandstone type, with indeterminable plant- and fish- 

 remains. 



Mr. W. Whitakee stated that the Lowestoft boring had gone 

 through Tertiary beds. Chalk, and Gault to the Lower Greensand 

 at about 1600 feet from the surface, but the water was salt and 

 useless. He still considered that New Red rocks might exist 

 under the London district, for the Dolomitic Conglomerate had been
