XI. On the Limestone Beds on the River Avon , near Bristol; with a 
Society having been pleased to publish in the 4th* volume 
beds of the Limestone series on the Avon, beginning from the Hot- 
wells, and lying above the coal No. 5, I have now completed the 
mighty fissure in which that river flows. 
This new series consists of above 300 more beds. It will be seen 
that in a few instances I have been obliged to resort to computation 
as to thickness, because there are certain spots inaccessible, owing 
to partial coverings of the soil, but I have been careful not to omit 
notices of any intervening depositions between the beds, marking as 
far as I was able the organic substances they contain. 
We now proceed from my No. 32 of the first seiies already pub- 
lished, page 197 of the 4th volume of the Geological Transactions, 
description of the Magnesian Beds that repose on their basset edges .

of their Transactions, the early part of my catalogue of the thirty-two 
measurement of the whole connected range, from its junction with 
the sandstone to its termination at a place called Cook’s folly, always 
accompanying the towing-path of the river Avon, and marking the 
Geological Transactions, Vol. IV. p. 197.
