360 PROCEEDINGS OP THE GEOLOGICAL SOCIETT. [March 12, 



plough and the harrow, as well as hy ice, the marks of which had 

 been almost entirely obliterated by human agency. 



Mr. Koch mentioned that in the late floods in Bohemia blocks as 

 large as 6 feet by 4 feet had been transported by the rivers, and 

 their surface had been striated during the process in a manner 

 much like that produced by ice. 



Prof. Ramsay pointed out that in some instances the transported 

 blocks had travelled over country higher than the parent beds from 

 which they had been derived, and considered that they afforded 

 some support to the theory of a great and general ice-coating, which 

 was immediately succeeded by a period of great depression below 

 the sea-level, and a subsequent emergence, the whole comprised 

 within one great glacial period. During these oscillations there 

 must of necessity have been a series of dispersions of boulders.

The following communications were read : — 



1. Note on some Brachiopoda collected by Mr. Jddd from the Jurassic 

 Deposits of the East Coast of Scotland. By Thomas Davidson, 

 Esq., E.R.S., F.G.S. 



[Printed as an Appendix to Mr. Judd's paper on "The Secondary Kocks of 

 Scotland," at page 196 of the present volume.] 



2. On SoLFATAEAs and Deposits of Sulphur at Kalahari, near the 

 Isthmus of Corinth. By Prof. D. T. Ansted, M.A., F.R.S., E.G.S. 



On the eastern side of the important spur of the Alps that stretches 

 down through Albania into Greece and terminates in the southern 

 headland of the Morea, there is a belt of low ground, some of it 

 below the level of the sea, and no part of it at any considerable ele- 

 vation, that has evidently been subject to volcanic outbursts up to a 

 very recent date. The island of Santorin, lying at some distance to 

 the south east, has very recently been the scene of one of the most 

 important volcanic eruptions of this century ; and some islands off 

 the eastern shores of the Morea have been subject to earthquake 

 disturbance, if not to actual volcanic eruption, within the historic 

 period. But there is, I believe, no record of the extension of this 

 belt northwards to the mainland of Greece ; nor am I aware of the 

 existence of actual solfataras, either here or in the islands in the 

 Ionian sea, or, indeed, on the eastern side of the Apennines, although
