Cleeve Cloud the Inferior Oolite attains an elevation of 1130 

 feetj the Cornhrash south of Burford is not much more than 

 one-half that height. This, however, is in some degree due to 

 the greatly diminished thickness of the underlying strata in the 

 latter locality. 



At Shipton Downs, near Burford, the 



Inferior Oolite is only 20 feet 



Upper Lias .... 20 „ 



Middle Lias . . .24 „ 



64 feet 

 And at Ascot there is even a greater diminution : — 

 Inferior OoHte . . .10 feet 

 Upper Lias .... 6 „ 

 Middle Lias . . . . 10 „ 



26 feet 



This law of " thinning out " does not, however, apply to the 

 Great Oolite, which has a greater thickness than at Minchin- 

 hampton. 



Mr. Lucy exhibited some good specimens of Fossils from the 

 Forest Marble of Shipton Downs, and others from the Stonesfield 

 Slate of Stonesfield. He gave a description of a section of these 

 last-named beds, pointing out that the fissile band from which 

 the Slates are derived is about four feet thick, and occurs at a 

 depth of 60 feet below the surface. He briefly explained the 

 variable character of this formation, and suggested that the 

 Club should meet for the examination of the Upper Cotteswold 

 district, with a view to correlate the same with the weU-known 

 sections in the southern portion of the county. 



The First Field Meeting of the season took place on Wednesday, 

 27th May, at Nailsworth. The programme for the day embraced 

 a visit to Minchinhampton and Avening. At the station at 

 Nailsworth, the attention of the party was directed by Mr. 

 WiTCHELii to an extensive land slip, caused by the Fullers 

 Earth beds shpping over the tmctuous clays of the Upper Lias, 

 to which action, perpetually going on, Mr. Witchell attributes 

 the gradual widening out of many of the valleys and combes
