It was unanimously resolved, by ballot,

 " ciety any Fellow being more than two years in arrear ; the name of 

 *' that Fellow having been suspended during one month, and it having 

 " been announced at two subsequent ordinary Meetings to be the in- 

 " tention of the Council to remove the said defaulter's name from the 

 " List of the Society unless his arrears be paid up."

A paper was read " On the Silurian and other Rocks of the Dud- 

 ley and Wolverhampton Coal-field, followed by a Sketch proving the 

 Lickey Quartz Rock to be of the same age as the Caradoc Sandstone," 

 by Roderick Impey Murchison, Esq., F.G.S., V.P.R.S. 



In previous memoirs the author has shown that the coal-field extend- 

 ing from Dudley into the adjacent parts of Staffordshire is surrounded 

 and overlaid by the lower member of the new red sandstone ; and on 

 this occasion, laying before the Society an Ordnance map, geologi- 

 cally coloured, he gave, 1st, A general sketch of the structure of the 

 coal-field in descending order : 2ndly, Detailed accounts of the Si- 

 lurian rocks which protrude through the coal measures or lie beneath 

 them : 3rdly, A sketch of the quartz rocks of the Lickey : 4thly, A 

 description of the trap rocks : 5thly, General remarks upon the dis- 

 locations of the stratified deposits ; and the dependence of these phe- 

 nomena upon the intrusion of trap rocks. 



1. Coal measures. — In most parts of the productive coal-field the

 greater part of which has been derived from the breaking up of the 

 new red sandstone which once overspread this tract, with which are 

 mixed, especially in the northern part of the field, a few boulders of 

 northern origin and some from the surrounding region. 



General and detailed sections are then given of the regular succes- 

 sion of the carboniferous strata ; for the greater part of which in the 

 neighbourhood of Dudley, and for much valuable information, Mr. 

 Murchison expresses great obligation to Mr. Downing; the best
