 above the weald clay. 



We have every evidence that the great valley of the 

 Medway, which runs parallel with, or indeed, forms a part

 shores of large rivers that these remain, recent as well as 

 fossil, are generally found. 



As soon as I saw the above bones, I sent to Mardon to

 waiting, in hopes of being able to give you a fuller descrip- 

 tion ; should, however, any thing more come to light, you

Sketch of the Oolite formation of the Cotteswold Range of 

 Hills, near Cheltenham, by James Buckman, Esq. 



The situation of the oolite formation of this district, as 

 before intimated, is immediately upon a bed of yellow clay, 

 forming the upper member of the lias formation. 



The high range of hills, called the Cotteswolds, are partly 

 composed of different beds of the freestones and grits pecu- 

 liar to the oolite formation. Some of these beds are of great 

 thickness, and to those who look minutely into their struc- 

 ture will afford sufficient data for sub-division into the 

 following groups.

 ordinate rocks. 



I. Pisolite, or Pea-grit,
