With this general section my own observations agree. Con- 
sequently over much of the ground between Kemble, Tetbury 
and Minchinhampton, a larger area of Forest Marble is shown on 
the Geological Survey Map than would be mapped according to 
the grouping adopted. 
The following are the principal divisions that may be found in 
the Great Oolite near Minchinhampton and Cirencester, further 
particulars of which will be subsequently given :
