The latter beds, previously mapped as Llandovery, are here referred 

 to the , Longmyndian. They also dip steeply westwards, and have 

 suffered considerable disturbance, accompanied by overthrusting 

 from the west. They are quite unfossiliferous, and neither on 

 lithological nor on structural grounds can they be regarded as 

 Llandovery strata resting unconformably upon the Cambrian. Their 

 nearest equivalents are found among the Longmyndian grits at 

 Hopesay, and in the Bayston Group of the main Longmynd area. 

 These Longmyndian grits at Pedwardine have apparently been carried 

 south-eastwards over the Cambrian along an almost horizontal 

 thrust-plane. 



There is also present a small remnant of Bala grits which dip 

 gently eastwards, and rest with strong unconformity upon the 

 Cambrian shales. The undisturbed character of these Bala Beds 

 suggests that the neighbouring thrust may be of pre-Bala date. 



Later faulting along a north and south line has brought the 

 members of these older formations against Wenlock and Ludlow 

 Beds. From the greatly disturbed character of all the Silurian 

 strata to the west of the inlier, as contrasted with the undisturbed 

 condition of the beds on its eastern side, it would appear that this 

 inlier is part of a barrier which has preserved the district lying to 

 the east from the effect of the post-Silurian movements. 



Annual Gteneral Meeting. 



3. February 16, 1912.— Professor W. W. "Watts, Sc.D., LL.D., M.Sc, 

 F.R.S., President, in the Chair. 



The Reports of the Council and of the Library Committee were 

 read. It was stated that 47 new Fellows had been elected during, 

 the year, and that the losses by death, resignation, and removal 

 amounted to 52 (1 more than in 1910), the actual decrease in the 

 number of Fellows being, therefore, 5 (as compared with an increase 

 of 5 in 1910). The total number of Fellows on December 31, 1911, 

 was 1,294. 



The Balance-sheet for that year showed receipts to the amount of 

 £3,029 19*. \\d. (excluding the balance of £452 19s. Id. brought 

 forward from 1910) and an expenditure of £3,007 75. 3^. 



Beference was made to the transference of the collections in the 

 Society's Museum to the authorities of the Natural History Museum 

 and of the Museum of Practical Geology, and to the consequent 

 extension of the Library. 



The Reports having been received, the President presented the 

 Wollaston Medal to Dr. Lazarus Fletcher, F.R.S., addressing him 

 as follows : — 



Dr. Fletcher, — In the long list of distinguished men who have received 

 from the Geological Society the Wollaston Medal, whether struck in palladium 

 or in gold, there are not only many geologists of great eminence for their 

 studies in other branches of the science, but a preponderance of those whom 

 the donor doubtless had more particularly in mind in founding his Medal ' to 

 promote researches concerning the mineral structure of the earth '. The list 

 does not contain the names of many pure mineralogists, but in asking you to
