geologists, to many of whom the position was a new one ; and as the 

 point in question is a good example of those " shakes" and " dislocations" 

 of such frequent occurrence throughout the Ootteswold district, the ex- 

 amination of the beds on both sides of the line of fracture occupied 

 the eyes and hammers of the party for some time. At this point the 

 " Great Oolite" is seen on a level with the overlying " Forest Marble" 

 and " Cornbrash," indicating a " down-throw" of considerable magnitude. 

 A good suite of fossils were here collected, principally from the " Corn- 

 brash," which yielded — 



Terebratula obovata, Myacites securiformis, 



maxillata, Lima duplicata, 



Avicula echinata, Echinohrissus clunicularis, 



Gresslya peregrina, Clypeus Plotii. 



From hence a walk down the line of railway to the Tetbury-road 

 station, afforded the party an opportunity of examining the small but 

 well-chai'acterised patch of " Bradford Clay," which is exhibited at that 

 point in the road-cutting between the station and the small roadside inn 

 close by. This uppermost member of the Great Oolite series is 

 but sparingly developed in any part of the Cotteswolds ; indeed I know 

 of no other locality in the district where so good a suite of its distinctive 

 fossils may be obtained. The following were collected by the club, and 

 noted upon the present occasion : — 



Terebratula digona, 



Rhynchonella coarctata, 



cardium, 



Claw of a crustacean, 



Fragments of Urchins. 

 From the Tetbury-road station the party proceeded to visit the ancient 

 entrenchment in the parish of Cotes, known as Trewsbury Castle — a 

 position as it would seem of some importance, judging from its extent — 

 which comprises within its area a space of some eighteen acres. It 

 appears difficult at this time of day to assign an object for a detached 

 camp of such extent within so short a distance of the great military 

 station of Corinium. That it was occupied by the Romans does not seem 

 to admit of a doubt, as coins of that people have been found on the site; 

 and during the visit of the Club a well-sinking had revealed portions of 

 pottery of a coarse description, to which the antiquaries of the party 

 unhesitatingly assigned a Roman origin. 



The Club was met at this point by the proprietor of the demesne, upon 

 which Trewsbury stands, Mr, Dewe, who most courteously invited the 

 party to partake of refreshment at his residence ; a proposal which met
