is believed to represent the foundation of what was once an abode of the 

 earliest inhabitants of the country, unburnt pottery of the rudest 

 description having been found in excavating a ditch which traverses 

 the site, and a tumulus in the immediate vicinity having been found 

 to contain bodies buried in a very remarkable manner, with the heads 

 resting upon the knees, a very early and unusual mode of interment 



Near this spot, a botanist of the party found a plant of the rare 

 Frog Orchis, Sahena/ria viridis. 



From the Seven Springs the party directed their steps towaids the 

 Black Horse, at BirdHp, where about eighteen sat down to dinner. 



After dinner Dr. Bird read some notes on the iron-workings of 

 the Eomans in the Forest of Dean, foUowed by observations upon 

 the strange waUs at Coedlthel, near Tintem, which proved so perplexing 

 to the Antiquaries on the occasim of the visit of the Institute to that 

 locaUty. These- he- pronounced to be of comparatively recent date, and 

 was supported in this view by Mr. Pttechas, who gave instances of other 

 waUs in the Forest of Dean of Hke construction, the date of which 



is known. , r\ ^'^. 



The exhibition of an example of Clypms Plotii, from the Great Oolite 

 near Cirencester, gave occasion for some interesting remarks by Dr. Wbight 

 upon the Echinoderms, with reference to their distribution and Umits, and 

 their value in determining the boundaries of strata, in which respect he 

 considered them inferior in value to the Cephalopoda. He stated that 

 he had traced Clypeus Plotii from the Lower Trigonia Grits to the 

 Cornbrash ; and pointed out the difference between this form and its near 



ally C. Mulleri. 



The last meeting of the club for the season took place on Thursday, 6th 

 September, at Cheltenham, where breakfast and dinner were provided at 



the Queen's Hotel. 



After breakfast the members proceeded to Leckhampton Hill, at the 

 base of which Mr. Nokwood pointed out the position of the Tpper 

 Lias beds, a section whereof had lately been obtained by weU-sinking on 

 the site of a newly-erected house. An opportunity so favourable is rarely 

 afforded for the examination of these beds, which are generally in the 

 immediate neighbourhood of Cheltenham covered up by ooHtic detritus. 

 Portions of Ammonites lifrons and fihulatus, characteristic of the zone 

 in question, were found at this spot by Mr. Noewood. 



The Oolitic Section at Leckhampton was next traversed by the party 



throughout its whole extent, and was thoroughly explained by Dr. Wkight. 



The Pisolite beds were first minutely examined, and the concentric 



structure of the grains well ascertained. The learned Doctor gave it 



as his opinion that these bods were accumulated in tranquil seas of
