The result of the boring, although very unsatisfactory to Messrs 
Rogerson, is extremely interesting and instructive Geologi- 
cally. It clearly shows, from the depth of 350 feet having 
been reached, that the Lower Lias is probably at this point 
400 feet thick. Mr Hutu in his memoir, at sheet 44, states 
that under Cheltenham the Lower Lias is supposed to be 600 
feet thick, but does not show how that thickness is arrived at, 
and states that southward, towards Bristol, the thickness is 
only 300 or 400 feet. The boring has givenus more definite 
information of the Lower Lias in this neighbourhood, and has 
added to our knowledge much that will be of advantage to 
future enquirers. 
This was the last Meeting of the season, and worthily 
__ brings to a conclusion these records of a season’s work of the 
Cotteswold Field Club.
