Vol. 60.] PROCEEDINGS OF THE GEOLOGICAL SOCIETY. V 



The following Fellows, nominated by the Council, were elected 

 Auditors of the Society's Accounts for the preceding year: 

 G. T. Frior, Esq., M.A., and F. W. Rudler, Esq., I.S.O. 



The List of Donations to the Library was read. 



Mr. J. Lomas, in exhibiting a piece of faulted slate from the 

 volcanic slates of Ulpha in Cumberland, said that the thin 

 band showing faults was very limited. The movements being con- 

 fined to this one strip, must be due to changes in the bed itself and 

 have no relation to larger movements. On tracing the faults on 

 one slab, cutting along the fractures, and reconstructing so that a 

 well-defined band was continuous, it was found that a horizontal 

 shrinkage of 1 in 6 had taken place. The faulting may be 

 due to the cooling and shrinking of an ash deposited at a high 

 temperature, or the closer packing of the particles as the mass 

 settled down. Similar small faults may often be observed in 

 Glacial sands ; and in this case they are obviously due to movements 

 consequent on a closer packing of grains. 



Mr. N. F. Robarts referred to the flint-implements which 

 he exhibited, on which he invited criticism, as Plateau or Eolithic 

 implements from the valley of the "NVandle, some of which were 

 obtained from the highest parts of the North Downs, in Surrey, at 

 an altitude of 800 feet. The implement exhibited, which was of 

 distinct Palaeolithic type, was from Croydon. He also exhibited 

 implements from the gravel at Mitcham, on behalf of Mr. A. 

 J. Hogg. 



Mr. Clinch remarked that, after a careful examination of the 

 so-called ' implements ' found in the gravel at Mitcham, he was 

 unable to see upon them any traces of human handiwork or of wear 

 arising from use by man. In his opinion they had been shaped 

 entirely by natural forces. He was glad, however, to see on 

 the table a typical Palaeolithic implement, much rolled and drift- 

 worn, which had been found at Thornton Heath. 



Mr. A. M. Bell acknowledged the working on some eoliths 

 exhibited, especially on one of the hollow scraper-forms, but saw 

 no reason to think them of earlier age than the ochreous and worn 

 Palaeolithic implement which was also shown. Probably, in fact, 

 that implement was older than any eolith exhibited — certainly it 

 was much more rolled and altered than the majority of them.
