III. Correlation with the 



Rustic of Neighbouring 



Areas. 



The earliest local Ehsetic 

 section to be described with! 

 sufficient detail was that at 

 Pylle Hill (Bristol), by the late 

 Edward Wilson, 1 and within 

 the last few years a number 

 of Rhaetic exposures in North- 

 West Gloucestershire ~ (includ- 

 ing the important sections at 

 Wainlode Cliff and Garden 

 Cliff) have been examined or 

 re-examined, with equal care 

 and wealth of detail, by Mr. 

 Linsdall Richardson. A sec- 

 tion at Redland (Bristol) has 

 been carefully described by 

 Mr. W. H. Wickes : ' ; while, 

 quite recently, Mr. A. Rendle 

 Short has undertaken the 

 minute re-examination of this 

 section, as well as of the Stoke- 

 Gifford cutting and of Aust 

 Cliff. Since, however, at the 

 time of writing Mr. Short's 

 paper is not yet published, and 

 Mr. Wickes has himself cor- 

 related the Redland section 

 with that at Pylle Hill it is 

 only necessary for us to point 

 out the correspondence of 

 the Rhaetic sections on the 

 South-Wales Direct Line with 

 those described by the late 

 Edward Wilson and Mr. L. 

 Richardson. 



Taking account merely of 

 the main features, all the local 

 Rhaetic sections exhibit the fol- 

 lowing general sequence : —
