WITH SOME GENERAL CONSIDERATIONS AS TO 



THE (UPPER AND LOWER) LIMITS OF THE 



RH^TIC FORMATION IN ENGLAND. 



By E. WILSON, F.G.S. 



{Curator of the Bristol Museum.) 



IN a paper read before tlie Geological Society of London 

 in the year 1891,* I described an excellent and typical 

 section of the Rhsetic rocks, which had recently been opened 

 np by the construction of the Bristol Relief Railway, at 

 Pylle Hill, Totterdown, on the south side of the city of 

 Bristol. Following the reading of this paper a discussion 

 arose, in which several geologists who have considerable 

 acquaintance with the Rhgetic rocks of this country took 

 part, namely, — Mr. R. Etheridge, senr., Mr. Horace B. 

 Woodward, Professor T. Rupert Jones, and the Rev. H. H. 

 Winwood. Although I had no reason to complain of the way 

 in which my paper was received on this occasion, one or two 

 exceptions were taken to certain of my views, to which, as 

 I was not present, I had no opportunity of replying ; whilst 

 upon one point my conclusions were, unintentionally no 

 doubt, distinctly mis-stated.
